Perrin CAI VS Greddy Intake
 

These are what I've narrowed my two choices down to!!! I would really appreciate feedback from owners of either intake in this thread!! I've read up on previous postings but would like to have input directly in this thread to make my final decision!! You guys are always helpful, appreciate the feedback ft86club. I am running the Greddy Evo3 exhaust and am curious to see which intake i should go with

For those of you that own the Greddy Evo3 exhaust input would be even more helpful, maybe even videos ?! :)

The Perrin includes a cleanable air filter. Now think about how often you wish to service the filter, and realize that each time you'll need to remove the front bumper. Sure, you don't need to service it that often, but I've heard reports of people saying that after a removals and installs, the bumper starts having alignment issues. though I've also heard people say that is not the case.

That is the biggest turnoff for me about the Perrin, and similar intakes that route the filter behind the bumper.

I own the Greddy intake and see no issues with it. Easy to install and easy to clean as well.

I think the Greddy looks better than Perrin too. Its easy to service, looks great, and adds to your Greddy collection. If I was in the market for an intake, i would consider the Greddy or Takeda

Is there a way to plug the hole for the sound tube on the Greddy? I was looking at those as well and would like the option to close off the sound tube.

yes there is!! I also had another quick question, will the pro dry s filter from the takeda fit on the greddy intake??

The aFe and Greddy are the same intake with different labels, so if it fits one it will fit the other.

If you're buying an intake based on looks instead of gains, what's the point?

Sound. if you dont have an obnoxious exhaust, it adds to the driving experience. Hence the stock sound tube setup...

sweet thanks for the input guys, decided on the greddy :) gonna get it installed tomorrow it's just sitting in a box right now :(

Go with the Perrin. Taking off your bumper once a year isnt that big of a deal which is the only downside of the Perrin CAI. It also is useable with some FI kits like the AVO and Innovate kits.

Perrin IMO is one of the best CAI you can get for our cars as it keeps the AFR's near stock readings. Greddy intake is nice but with the Perrin you will always be getting cool air since it is placed outside the engine bay. Dyno's have shown it to get 5-6~ whp from some independent dyno's done by customers. Spend 150 more on the Perrin silcione tube and from what some customers have said it adds about 2-3 whp when combined.

Cant go wrong with the Perrin CAI, but the one thing I like about the AFE/Greddy is that they have a dry filter option which can save you some troubles of oil getting on the MAF sensor. If you dont mind oiled filters then go with the Perrin. It sounds great and gets good gains. IMO you shouldnt upgrade an intake unless its a true CAI. If you get a box intake like Greddy/AFE, Injen or anything that sits in the engine bay it isnt worth it as the stock air box is already well designed. Drop in filters already get almost as much as most of those intakes so its better to just get a true CAI like FA20, Perrin or anything that sits outside of the engine bay. You get cooler air and it sounds excellent. A drop in filter and a intake duct is the best option if you dont want to get a CAI like Perrins that needs to remove the bumper to clean. IMO you either get an intake duct/drop in filter and or a silicone intake tube or a true CAI like Perrin or FA20. The Intake duct/Drop in filter and the Perrin both are useable with some super charger/turbo kits so if you do decide to go that route in the future you wont need to sell your intake since its reusable.

If you get the Perrin CAI you should get a tool that removes the clips for the bumper. I think the alignment issues are from people who mess the clips up so it doesnt sit well. The tool is very cheap, like 10-15 bucks and it will make removing the bumper much easier. You might as well get it if you get a true CAI as it will be useful and make sure your bumper stays aligned by not messing the clips up.

The spot the Perrin CAI is at is where the OEM air scoop is at so it will get clean and cool air. Air will enter just fine and the bumper wont effect anything when you are driving. If you upgrade your intake either get a true CAI or get a drop in filter and call it a day. Get an intake duct/silicone tube to improve the OEM design even more by getting rid of those restrictions. A drop in filter/HKS air duct/Silicone tube will perform just as well as any intake box that sits in the engine bay. Any intake that sits in the engine bay will be more prone to heat soak than a CAI or Oem air box since they use materials that are more prone to soaking up heat. From what customers who own the silicone tubes say they all have said that when you touch the silicone tube after driving around a little it is warm not hot. Which is great as it doesnt soak up heat like other intakes.

That is exactly why I would go with the Perrin CAI as it looks great when you have the silicone tube with it. You get cool air and it has good gains for an intake while keeping the AFR's near stock numbers. Almsot every intake gets gains by leaning out the AFR's which isnt good for your engine long term. All intakes that sit in the engine bay IMO arent any better than the stock air box with improvements to the restrictions like I said above. 5-6 WHP with it possible to get 2-3 more whp with the silicone tube/duct is well worth it IMO. Perrin claims that with their header back that the silicone tube adds about 4 whp when it is used with the CAI/Headerback.

I second the Perrin cai if you can swing it. Removing the front bumper is not that big of a deal. I removed my front bumper from a s4 that was way more of a pain than the front on the brz. It seems you have already made up your mind though.

@eddieEndo
Perrin hands down is the better intake. No intake that is placed in the engine is worth getting unless its a GruppeM if money wasnt a factor but that is way too expensive just for an intake.

IMO Greddys/AFE and every other intake that sits in the engine bay are just overpriced drop in filters. If you look at the D-Sport intake article almost every single intake doesnt perform any better than a drop in filter with the exception of 1-2 intakes and that is just by 1 maybe 2 whp. I dont think 1-2 whp is worth it to pay 300 dollars more when you can get similar results with a drop in. A drop in gets 5-6 whp. In an intake shoot out thread where they compared the AFE/Greddy(6-7 whp), Zeta Silicone tube and drop in filter(6-7 WHP), Injen(10-12 WHP, but leans out the AFR to get those numbers), and AirRaid(lost a lot of power) intakes, The Zeta Drop in/Silicone tube got 6-7 whp. The AFE/Greddy got just as much and cost twice as much. And that is with the Zeta silicone tube which isnt as smooth as Perrins silicone tube as it has a smoother bend than the Zetas/AVO which is just a 90 degree turn. If you get all 3 you are probably looking at the same performance as the AFE/Greddy and possibly maybe 1-2 more whp as intake ducts cant be measured just on a dyno.

Intake ducts have shown to get small gains on a dyno but its true potential is seen when you are driving at 60-80 MPH as you cant imitate that on a dyno. An intake duct/drop in filter/silicone tube will cost just as much as the AFE/Greddy and will IMO either perform just as well on a dyno if not better. I would not be surprised to see a combination of those 3 parts to improve the restrictions of the OEM air box/Air scoop/Orchodion tube to perform slightly better than the AFE/Greddy intake. With a tune it would be even better as almost every intake for this car have gotten little to no gain. But with the improvements to the OEM air box I could see a tune make much better gains since it is using a set up that is very close to the OEM air box. The Syms intake duct got 8 WHP/10 WTQ. So a set up of a duct/drop in filter/silicone tube should net nearly as much as what the Syms got. That Syms intake duct was with just the OEM air box and most likely a Syms drop in filter so it still has room for improvement with a silicone tube to replace the orchodion tube. The Syms intake duct is much larger but the HKS duct should still see decent gains as it is improving the restriction of the air scoop by a lot.

A Perrin silicone tube is 130~ dollars, HKS air duct is 200~ and a drop in is 30-40 bucks. I am sure you can get a discount too since you are a member on this forum from some vendors here as they have shown to always hook it up. That comes out to nearly as much as what the AFE/Greddy cost maybe a little more but you also pay for a slightly better performance.

A Perrin CAI/Silicone tube cost 400-450 ~ dollars depending from who you get it from and a TRD intake is 400-450. Greddy/AFE cost about 350. And an intake duct/Drop in only costs about 200-250 for only those 2 parts that should get the same whp results as what an AFE/Greddy intake get. Add the silicone tube and it should perform slightly better on a dyno and A LOT better in real world driving conditions than the AFE/Greddy that cost just about as much as the intakes I just listed. Ducts IMO have always been one of the best mods you can do for cars with a well designed air box from the factory. The s2000 comes alive when you just add a spoon in take duct to the factory air box and you can feel the difference when you are going 60-80 mph. So just say an intake duct/silicone tube/drop in it did get the same results as a AFE/Greddy on a dyno, just imagine when you are driving at speeds of 60-80 mph and how much more air will be sucked in to the air box. A dyno fan probably isnt even close to how much air you can get when you are actually driving at freeway speeds.

Like I said in my previous post I would go with the Perrin CAI or a drop in filter with the option to add an intake duct and/or a silicone tube. Doing just 2 of the 3 for the OEM air box will already net you numbers that the AFE/Greddy already achieve for 100 - 150 dollars less depending on which 2 you get. All 3 you are probably looking at maybe 20-30 bucks more than you would pay for the AFE/Greddy and a little less than what you would pay for the Perrin CAI/Silicone Tube but you also get better results. All you get from getting intakes that sit in the engine bay is sound/looks along with a greater chance for heat soak which will greatly effect the performance of your intake, For example like what 2forme said in another thread when you sit at a red light for 5 minutes the heat from the engine will drastically effect the performance of the intake because of all the heat it is soaking up. You dont need to worry about that with the Perrin CAI or any other TRUE CAI and they all look great and IMO sound the best compared to the intakes that sit in the engine and they also will constantly be getting cool air instead of soaking up heat from the engine. If you get an intake you should really be getting it just for the sound/throttle response. Most of the power you get is from other bolt on mods like a full exhaust which will net much bigger numbers. I went with getting a full exhaust first before upgrading my intake because I just dont believe that the extra air an Intake would bring in would do much if your exhaust is still restricted and the exhaust also sounds great which is a reason why people get intakes for the sound they make so you still get a better sounding car while increasing your whp/wtq. In my previous post I also brought up that you can use it with some FI kits where as the Greddy/AFE you cant. I personally have a Cobb Dry Drop in filter, Perrin Silicone Intake tube, and in the process of ordering the HKS air duct. If money wasnt a factor I would get the Syms intake duct or GruppeM intake. Both are carbon fiber beauties and are probably 2 of the better intakes you can get.

Sound != looks, my comment was purely about buying an intake based on how it looks. All intakes will sound pretty similar, so if you're after function get the one that makes the most power. If you just want noise, get a louder sound tube generator thing from TRD, or get a drop in panel filter.

The Perrin CAI does keep the stock sound tube though, so you'll get more intake sound AND have the sound generator available if you want more noise. You only lose the sound tube if you get the Perrin inlet pipe as well, but you could always get a different inlet pipe that keeps the sound tube.
