HP Gains per Dollar Intake Chart
 

DISCLAIMER: These results are taken from various dyno tests from this site and where there was no data available, manufacturer's claims were used. Other factors such as environmental, tuning and safety were NOT taken into consideration. When in doubt, always consult with an experienced tuner when making changes to intake systems! This is only meant to provide one place where aftermarket intakes can be compared side-by-side in as similar conditions possible with APROXIMATE RESULTS!

OK, before I get into the meat and potatoes of this I want to say that I apologize if it seems that I am picking on any particular manufacturer or trying to push any product. This is not scientific, I am not a tuner, I didn't do any of my own testing, and I am all too aware of the cost variances depending on where you find these intakes.

I'm just some guy on the internet that had a little time on my hands this afternoon so take it as that.

Now then! I have compiled a simple chart that shows the main manufacturers of intakes, retail costs, and subsequent gains (most of them are the result of averaging out various claims.) and the approximate HP-per-dollar figure is last sorted from Best Value to Worst Value.

Obviously, if you can find any of these intakes below retail (which isn't hard) then that will skew the numbers a bit but since the retail prices were set by the manufacturers, I thought it was a good place to start.

I tried to grab independent dyno results where I could and where I couldn't find any, I used the manufacturers' claims. I also only tried to use dyno results with NO tune.






Here's the list.

* Read this as you are paying $28.81 to have each hp removed from your car.
** More data needed.

Sorry for the hell-storm, flame-war that is about to ensue, but I thought this might be a good way to show these products in a simple way to compare them side-by-side in one place. Well, at least until an un-biased, professional shop with the dyno, budget and time decides to make a more accurate assessment.

Please let me know where I made mistakes and I will correct them ASAP!

NOTE: If anyone has links to better dyno results, please let me know and I will incorporate them!

I really need to stop drinking Jack Daniel's at my desk. I posted this in the wrong section.

Mods, can you please move to the Technical Section with my most sincere apologies?

Scott

if it had been in the right place, i wouldn't have seen it.

thanks for the mistake :D

good mistake. interesting data.

You should denote marks from MFG dynos, and Independant testing.

Injen looks like the best buy...I'm just scared on the problems some have reported :sigh:

Injen and Air Raid looks like best bang for your buck. Though I never heard of Air Raid before o_O.

Read again, Air Raid is the worst! You lose 16hp! I was confused for a second too

You should do a drop in filter chart.

No love for drop ins?

oh snap! didn't see it was a negative next to it lol. that's horrible!

Interesting that there's a delta betweeen Greddy and aFe, aren't they the same unit?

Same unit but they use a different filter cone

I cant stop laughing at that air raid. I want to read one of their promos for their intake on their website. Has to be full of complete horseshit.

Yeah Air Raid is bad for your car, especially up top where it chokes up

For what it's worth, my Injen intake = $21.54 hp per dollar (For what I paid)

Have you had yours dyno'd? If so, did it produce similar results to what is listed here?

Lol, you forgot the ebay tornado intake mod for 21 hp.

These numbers are pretty bogus. Perrin 11 hp? Injen 13 hp? riiiggghhttt....

But Sportsguy, manufacturers NEVER inflate numbers to make sales... :iono:

Yeah, the Injen tests were with an open hood... lol. Try it with the hood closed in a more realistic environment.

Want to see Injen intake tested on Third party review with the hood closed. I cannot find it but I think you can help out.

same i like injen but maybe i should just wait a while for more intakes

Here are 3rd and 4th gear dyno results for air raid, AFE, AVO, and Injen

Guys, seriously, relax.

Please re-read my post and I don't think I could have stated any clearer that I am just some guy on the internet, not a tuner, and just gathered what I could find.

Besides, I didn't see any of you offering other information while you were bashing what I found (which most of which is from THIS SITE!).

I knew this would result in some hurt feelings but honestly, some of you really disappoint me with your quick desire to shoot someone down without offering any useful insight.

So I tell you what. Why don't you re-read everything I said, go find something useful and we'll post it. I have no vested interest in this and couldn't care less about the order of these products. Just trying to be helpful which is more than I can say for some of you.

Scott

Blows my mind that a company would make an intake that loses 16 hp on a 200hp engine. U probably can't do worse if u tried to make 1 outta plastic elbows from home depot and a pep boys filter. I think it would be in air raids best interest to work on that or this will be a bit of negative pr.

Try a new post with third party dynos on all the intakes rather than including any manufacturer dyno. Everyone knows a short ram intake doesn't push 16 whp and when people read this, they're going to jump to an instant conclusion without reading the post like 90% of people do and say, OMG I'M BUYING AN INJEN BECAUSE THIS POST SAYS 13 WHP.

I'd be really surprised to see the Injen outdo the Perrin, Vigilant, and FA20 cold air intakes with that heat under the hood.

I get what you are saying Matt but again, please re-read my post. I never posted 16whp gain anywhere. Drift Office found 12-14whp gain with the Injen so I called it at 13. If you have a problem with Drift Office's dyno testing, take it up with them. Funny how nobody is arguing the 16whp LOSS that Drift Office found with the Air Raid intake.

Personally I am skeptical of any claims that an intake makes more than 8whp but that is what an independent company found and I am not qualified to call BS on them.

I don't have any data for the Vigilant or FA20 CAI's but if you do, I'll be happy to add it.

Scott

NOTE: When I get back to the office tomorrow, I will place links to where I found the HP claims for each product to eliminate confusion.

I didn't try to shoot down what you did and I'm completely relaxed. In fact, I won't even be buying an intake system. My recommendation for a disclaimer is based solely on the fact that as Matt correctly said, 90% of the people read thread title, read gains, doesn't care about a single word on the rest of OP. So, to help those people that don't like to read much and are noobs when it comes to modding the car, I suggested a little help via a big disclaimer that is visible and won't require them to dig into the post.

You would be AMAZED at the number of people that do exactly as I described. They read a number, take it at face value and throw money away like flushing it down the toilet :thumbsup:

I don't disagree with anything you said. In fact, I couldn't agree more.

Tomorrow I will make some of the disclaimers a bit bigger but ultimately, nobody can help people that aren't willing to read. It only took me about 45min to compile that info and anyone that really cares about getting the right part for their car wouldn't need someone to "hand it to them". Still, sometimes I get these fleeting feelings of charity. I promise they don't last.

Scott

Very very very true!!

People who bitch about dyno with hood open or closed need to get over them selves.

Someone dyno'd their INJEN intake with their hood closed and it performed a bit less than it with the hood open. People who keep saying shit about real world driving conditions n bs like that need to realize dyno's are just their to gauge if theirs any improvement with the mod or not.

Everytime I always see people bitching about an intake dyno'd with the hood open or closed saying its not realistic need to shut it. Vendors do it to show us the gains and people do it for peace of mind. Hell why even do it in the first place if its not "real world driving conditions" like you want. Either way having the hood open so the heat doesnt soak up is fine to me. When your driving on the freeway it wont be soaking up hot air like it would be if your on a dyno with the hood closed.

I can find 2-3 threads of the intakes in the OP's post that have had dyno's done with the hood closed and open and they both performed similar maybe a little less but honestly who cares. People dyno so they know the product they are buying is performing as advertised. 3rd partys and shops have dyno'd most of these intakes and all have gotten good gains. Maybe not as high as what the companies claim but they are an improvement which is all that matters.

Drift office gave us dyno's and did it again on there test cars which they did not have to do. Those are as close as you will get in terms of information for the intakes unless you do it your self.

LMAOOOOO -16!! thts some nice trolling by airraid

This...seen the other post of the injen intake and gave magnificent gains with the hood closed on a dyno.

Give me an Injen intake and I'll show you how it performs in 102 degree heat in the summer.

I think it also might be worth noting the safety of the AFR curves for each intake. Sure one can make 10 hp, but if it leans you out to 13.5 and above... it's not really that safe for engine long term.

I think something was wrong with that dudes car. I mean, he was making 90 ft lbs of torque at redline for the stock pull.... thats 20 less than most cars.

Wouldnt a tune solve that issue?

It would, but it would also very likely negate anything the filter did on its own, in that case. A lot of these intakes for the BRZ/FRS get their power by messing with the AFR. If your tune adjusts it anyway, you may very well find that you were better off with just a tune in the first place. Assuming maxing performance/efficiency was your only concern, of course.
