Default Intake on my 06 2.5i w/pics

I recently had an intake installed on my stock 06. It was put on Saturday at All Aspects by Vern. He pieced it together himself and did a great job. I've been driving for work and have traveled around 100 miles with it on. The car is noticeably quicker and sounds pretty neat .

He did a base line and a dyno run after putting it on.


Please excuse the night shots. I decided to take these at the last minute.



He t'd off the two valve cover and the crank case breather lines and ran then into the intake.

to keep the filter from moving he attached it to a bolt right below it.




he did a great job and I'm definitely going back there for anything else. I can't wait for Kienan to get the OpenECU to get it tuned and see what happens.

Very nice, thanks for the pics & driving impressions, keep us updated. I'll be installing one of these on mine this weekend, as well as installing my Tactrix cable to start data logging.

P.S.:quick tip since I don't see one, get a grounding kit installed, and make sure 1 of the wires attaches to the bolt holding the throttle body on. Doesn't fix the DBW issues, but I noticed an improvement in throttle response.

But .... but ... but ... the stock intake is better! If you remove the torque box you'll lose low end torque!! My butt dyno says so!!

Nice to see further proof that all the naysayers that claim aftermarket intakes are bad have no idea what they're talking about. Note that the AFR curves for the two runs are essentially right on top of each other, which shows that the gains you're seeing are strictly from making it easier for the engine to suck air in. That's just basic Engine Mods 101, but so many people here (for some reason) don't believe it.

very nice! Think you could possibly get some close ups and/or clearer pics? I might wanna do something like that with a buddy of mine. But I can't see where all the connections are going to in the above pics

Those are some really good gains for an intake. Almost 15whp, and about 12 lbs/ft torque to the wheels is nothing to sneeze at. The new 2.5i seems to be responding really well to mods. Would be interesting to see the gains with an intake, full exhaust, and some sort of em. Keep up the good work.

I did an eBay custom intake to my wife's 06 Legacy and noticed a nice power increase. Nice to see that it's proven on paper. There is a thread about it on legacygt.com. Bunch of people have done it. I'll be doing one to my new Tribeca soon, too.

My question is, what did he use for the MAF housing?

I believe it's the stock section with an adapter for the filter and the silicone coupler attaching the tube on the other side. Probably a good idea, perhaps better than a true aftermarket intake that would mount it directly in the intake tube, since I believe changing the diameter of the tube the MAF is mounted in could throw off the readings.

"You wouldnt happen to know what thats giving you at the crank would you?"

based on factory specs of 173hp/166tq at the crank stock it would extrapolate out to approx. 190hp/181tq based on his stock VS intake figures.

Not at all, water doesn't typically reach the top of the engine bay unless you wanna drive into a lake.

thanks for all of the positive input and i'm glad to see so much interest so quickly. it gives me hope for the NA people.

lYNEl: the intake was put together by a guy Vern at a local shop, All Aspects.

SubaDuba420: Good luck with the install this weekend. if you have any questions feel free to ask in this thread and I'm sure Vern (Vmiz on the board) would be willing to help, and i will if i can. I'll definitely look into the grounding thing. thanks for the advice. You are correct that the stock MAF housing was used and how it was used.

J-Chow: I'll try to get some clearer daytime pics when i have the time, i just figured something was better than nothing for now.

Just on for a break at work for a sec, i'll check back later today when i get the chance.

I thought people said that were talking about intakes on the WRX and STI. He has a 2.5I. Big difference.

Nope, once speculation spread; ppl assumed he was right, started to spread the word and none backed it up

If there is interest in having these made specifically for our 2.5i's let me know. If needed I can have a prototype out in 2 weeks . Will look very simular to one posted above. I will also just have a adapter and filter kit so you can just use stock intake tube.

Props on the dyno results. I must say im very suprised. Never seen a NA car so restricted through the airbox before. Looks nice.
