Which intake fits my requirements?
 

Yes, I know they don't make any power once tuned compared to stock. However, I want to clean up the engine bay.


Requirements:


1. Doesn't interfere with oil cooler lines (I'll be using the Jackson Racing setup).
2. Don't have to remove the bumper once per year to clean the filter.


Thoughts?

I have installed a mishimoto intake which iirc has a 4" filter without removing the bumper. I also have installed a number of FI intakes without removing the bumper. You can remove the T bar behind the radiator which is 2 bottom bolts, 2 top, and 2 that are tight to get tin in front of the bumper (accessible via a wrench) and then you can tug the bumper slightly and get just about anything in there.

So basically any of the intakes work. Personally I don't like the injen intake as it has a lot of turbulence. Grimmspeed, mishimoto, and perrin have the least turbulence in the order i typed listed.

My Grimmspeed was that good, eh?

It's my understanding the GRimmspeed needs to have the box dented to not rub on the lines. Otherwise that's what I would have liked to purchase.

The Grimmspeed is the only one of the three listed that actually has an airbox, and yes, one member did have to dent the box in slightly to not interfere with his oil cooler.

You don't by chance have a link to the thread? Or what oil cooler he was using (or does it even matter?)

What about just running an aftermarket inlet tube (without sound generator tubes) on the stock airbox? That cleans up the engine bay as much as the Grimspeed intake does.

for what it's worth, I have the G/S intake and OEM oil cooler.. I know, doesn't help at all in your case. ha. Clearance of the airbox is akin to stock; if you can get the JROC's fittings to rotate away from the box a little, it would probably be okay

Your link was a follow-up to that later on. There's good technical detail in both threads but photos in my link :)

Also @wparsons I disagree that just a pipe cleans up the engine bay as much as a full intake. You don't even need a pipe to delete the sound generator - I did that almost the first weekend I had the car. Then, later on I got the Mishimoto pipe. The difference between that and the GS in substantial because the stock airbox is enormous in the engine bay. I mean, look at this difference:

plus that sexy wrinkle-coated METAL intake tube... :wub:

*throws cash- no gains? no care*

^Precisely.


There is also the big resonant chamber connected to the stock airbox as well. Thanks for the links gents!

GS has proven gains - read their development thread. It's one of the most well documented product developments in the history of the internet (I'm not exaggerating).

Further, there is no heatsoak. The logs from my OFT prove as much. The velocity of the incoming air is such that heat doesn't transfer all that effectively. I've been hearing the concern about intake heatsoak for over 10 years and I've never seen it actually demonstrated with data.

brother... I made a custom tune for the OFT v2.06 map for the G/S Intake and OFH. 4 revisions of the MAF scale, countless logs and tune tweaks.. I know a little about the intake :). I don't know what you mean by doesn't heatsoak, it's very efficient but heatsoak does happen. It is mitigated by the aluminum box and flow design... but it does happen.

In traffic all intakes IAT will rise, nothing helps against that except for heat shielding, and even then it's not uncommon for intakes (this one included) to surpass 100-120F in traffic, depending on ambient temps.

I can also help you re-scale your MAF (yes, the factory MAF location is designed into the G/S Intake, but trust me.. the stock box is far from this one) if you want. Just let me know... love my setup, but I'm going to underline that the stock airbox is NOT restrictive, so in my mind, no gains. A tuned stock airbox with a high-flow filter will be within 1-2WHP of this G/S box... sooooo.... unless your butt dyno is calibrated better than a MaHa, it's a wasted $300-400 bucks if someone's trying to budget build for power.

Ok, I misinterpreted your post. That's on me.

To clarify what I was talking about with regard to heatsoaking...In my experience, and this goes back to the GTO community I was a part of from 04-08, when car kids argue about heatsoaking on intakes it tends to refer to increasing IATs as a result of the box itself getting hot - i.e. a metal box transfers more heat into the air and thus will be hotter. Which is nonsense, as experience with tuning and monitoring bear out. Yes, IATs will definitely be high in traffic. With any intake, including stock, no matter what it's made out of or how well it's insulated. But as soon as you're moving, it'll drop back down to very close to ambient. Again, that's with any intake.

And yeah, WRT your tune, I have noticed that from the OTS Grimmspeed Stage 1 tune I could stand to do a little work on the tune as my LTFTs never get down below about 3-5% but it's been so bloody cold lately I haven't messed with it. I'm not going to tune for the 60 days a year of solid below zero temps, know what I mean? That said, IAM is always at 1.00 and I never have any knock, but it could definitely be a little better as the LTFTs show.

Definitely- if there's no knock (a little FLKC doesn't hurt things) and IAM stays pegged, you're probably alright. It seems strange Shiv spoke so nicely about the intake but the OTS tune is so far off it's weird.. has me thinking something else is going on over there

I am in the same boat as you- I am worried that it's a shit time of year to do tuning; Washington has a ton of variance in weather so I'm thinking of creating two tunes, one for summer, one for rest of the year.

When things clear up, hit me up and I'll lend any support I can. I use @vgi's Java plugin and Steve as my advisor for when I don't understand something, haha.

I am also playing around with zeroing out the IAT comp table and tuning from there, but I don't understand that approach yet so I'll let you know if I make any breakthrus on that front

Well, I advocate a lot for OFT but it's true that an OTS tune can only go so far. They tuned at some shop in Southern California at say 1,000' altitude on a 70+F degree day and I'm sitting here at sea level at below 30F. It does make a difference. More air so there's more fuel needed to get to the commanded AFR (which it's always easily in reach of).

Bumping this, has anyone used the AFe Takada intake with an oil cooler?

What about the Skunk2 airbox?
 

What about the Skunk2 airbox? It clears the Skunk2 oil cooler lines. Though I don't have an oil cooler yet, here's a picture of it installed. I'm using it without the restrictor, so it's a little over 3" wide through the MAF adapter, and it has air straighteners inside to restrict turbulence. It's made of heat resistant plastic material to resist heat-soak better than metal intakes. It makes enough power with my long-tube header to squeal the tires from a standing stop in an automatic, and that's more than my stock intake could do. It also has a rubber ring where the tube passes through, which ingeniously absorbs the engines' torque thrust against the body-mounted airbox. Other setups can work their way loose while this won't.

FYI, Grimmspeed is working on a solution for the airbox to work with oil cooler lines, and plan on letting the initial crowd of buyers looking to use an oil cooler swap out with the revised box when it's ready.

There's no ETA on this yet though. Grimmspeed takes good care of their customers.

GS, don't look back. Wait for the update re: oil coolers if its that much to you, shouldn't be to long.

Grimmspeed Intake all the way.

Exactly, any canned maf scaling from any vendor will never be as good as doing it yourself
altitude
temperature
fuel formulation
fuel ethanol content ie 0 to 10 or so % in petrol

and variations in the actual maf sensor itself due manufacturing tollerance or revisions, their apears to be at least 2 variations. mine always ran rich and i see it in other guys logs as well, some run rearly good and some like mine run about 7 to 10% rich on stock intake. even on stock tune and intake.

Yes, not being able to have an oil cooler is a deal breaker.


I want to get back out on track since I parted my Miata last year.

The Perrin is pretty solid if you don't mind fiddling with the front bumper. Can be done without removing it but it's a little trickier.

They're updating to allow oil coolers, so soon.

While you likely want to fine tune, MAF scaling doesn't seem the mess it is with so many, and that's a safety issue too. Is the basis of my recommendation, at any rate.

^Yeah, I'm just curious how long that will take. I suspect it will be months down the road.




I wouldn't mind pulling the bumper to install it, since I'll have to pull the bumper to install the oil cooler.


But having to regularly pull it to clean the filter, that's not so appealing.

just the JRSC oil cooler or SC/oil cooler combo? The SC will replace the intake if this is the case

Just NA. No desire to drop $7k on FI......even if I had that laying around!

Had the exact same question. Installed a Perrin oil cooler (seems to have the same sandwich plate as the JRSC cooler), but the fittings touch the stock intake box.

Here are the intakes I've seen that clear out space in front of the oil filter, but might be prone to heat soak.

HKS Racing Suction Reloaded

Tuning those intakes looks like a nightmare due to MAF placement. AMR one might not be too bad if it has an air straightener.

Not to mention sucking all that hot beautiful air off the back of the radiator.


*facepalm.png*

The HKS comes with a heat shield, that would be my only pick of the bunch. A company like HKS wouldn't release something like that if it really didn't work.

Companies release what they think will sell. Sorry.

Find me some data on the HKS intake like some of the vendors like Grimspeed have produced, and then we can chat about it.

Otherwise, you're just being an uniformed fan boi.

Would I buy the HKS above? No. Ani an HKS fanboi? No. However HKS do have a good history of R&D and the rest of their offerings for this platform and many others are pretty much all proven, so why is this any different? This is much better thought out than just a filter on a tube, despite the looks. It is however designed to be a racing intake, so CATs will not be different when the car is moving to the stock intake, however it will clearly heatsoak when in traffic.
