Thanks man! I kinda figured it wouldn't be much of a gain in terms of power. I was looking into the mishimoto race intake which had larger diameter piping but does need to be professionally tuned. The only downsides is that it's not CARB legal in california so no shops are willing to sell them to me. But I want my car to sound like a race car! lolThe largest gain would be in the noise level. Performance gains from CAI on a stock tune are questionable at best, especially on modern vehicles. It is my opinion that 'lite' modifications like this gained popularity before the 90's when cars started being much more efficiently designed, and today they are just a cash grab marketed to cool kids. Your 2.0L puts out nearly 300hp. The Grand National was a fast car in the 80's. It made about 240hp 3.8L turbo, however with further modifications and the help of McLaren they made it up to 300hp.
Your XT has decades of Subaru's engineering poured into it. It has roots in rally. I would put money on the idea that the intake system is exactly how it should be, and no aftermarket system will make a significant impact.
Yeah, true. I'm just referring to aftermarket utilization though, like the Cobb SF intake for example. Same intake ducting, just flashier, more expensive filtering and plumbing for a louder WHOOSH on throttle, heh.The OEM intake is already a CAI.
Hi there, what would be the normal operating STFT and LTFT on a stock tune XT? ThanksAgreed with @RyanT comments. I'd also be very careful of companies saying the intake is safe with a stock tune. At a minimum, checking STFT and LTFT will be important to ensure your engine is operating safely. In the WRX FA20DIT land, they are running stock intakes on Stage 2/Stage2+ vehicles with no issues. There is a little additional power the tuner can extract, mainly due to increased airflow.
Yeah I already have TGV/EGR deletes, grimmspeed TMIC, and the invidia q300 exhaust. Also already been e-tuned. Just wondering if adding the CAI would actually net me some real gains other than just added noise. But the consensus seems to be to keep it stock.Install a CAI, gotta tune it, aftermarket exhaust, Invidia q300, gotta get a tune, EGR delete, gotta get a tune. TGV delete, gotta get a tune etc etc. You install it you tune it, you drive it, you have fun. Stock? dont touch it. Install a new aftermarket head unit, gotta get a tune??
This is also I am looking into. Keep the box stock and fabricate a stainless steel pipe to replace the stock intake "rubber hose", Just wondering if anyone has done this and what was the outcome?Yeah I already have TGV/EGR deletes, grimmspeed TMIC, and the invidia q300 exhaust.

Save yourself the time and effort. A metal pipe will become a heat sink and perform worse than an insulating (read: plastic) piece.This is also I am looking into.

Really curious why stage 1 always includes a CAI ....Save yourself the time and effort. A metal pipe will become a heat sink and perform worse than an insulating (read: plastic) piece.
The new MAF scaling on the FA's is incredible touchy, and the last thing you want to do is mess with it for underhood "bling". The factory intake is plenty capable of supporting north of 350whp before it should even come up to be "improved" upon.
"Stage 1" cars are typically nothing more than a tune and a catback, and can readily be turned back if needed with minimal/no hardware changes. "Stage 2" modifications typically include downpipes/j-pipes, intakes, and other supporting mods- most of which require individual, vehicle-specific tunes to get the most out of the modifications (read: run safely without being a time bomb). Companies will sell you whatever flavor of intake noise maker you want claiming some performance gain; "stage" or not, they make money.Really curious why stage 1 always includes a CAI ....
