Intake Questions
Okay, so I have done some research regarding intakes for our cars and I see that overall our cars require a tune after installing an intake regardless of brand (i.e., AMS, UR, etc). However, some people say that as long as you have an intake in which the diameter of the MAF sensor housing tube is the same you do not require a tune. I also heard that Injen's CAI for our car does not require a tune either.
Any thoughts on this?

basically all an after market intake does is lean out the AF by letting more air flow. Anytime you start to lean out the mixture to far a tune is required. However if the mass air is the same size I would think youll be ok. Not really sure, When I had my Mustang I had an C&L 85mm mass air and 75mm TB and Plenum and leaned the **** out of my mixture. MY AF was all over the place before my tune. I drove it that way for a long time and I was luckly not to do any real damage to my motor. The best was to be sure is to install and hook up to a wideband and see what your af is. I say its a crap shoot.

As long as the MAF housing stays the same size then the car should be able to adjust itself.
When I was doing research on CAI's the only reason people were having to get retunes was because the MAF housing was larger and unmetered air was getting through, leaning out the mixture. As long as all the air is metered the stock tune can look after itself.

wrong, the maf housing on the UR intake is the same size. They require the tune because of the drastic change in the amount of air being sucked in at a given throttle.
the maf /ecu cannot compensate enough.

Is the stock system so bad? Looks pretty efficient too me. As well most of the aftermarket kits are just going to draw hot air from the engine. Its not like the stock intake is a bottle neck and robbing the car of power.

Have a good read through this thread. Almost all the tuners give their opinion regarding almost all intakes currently on the market.

The stock intake system is actually quite wonderful. It's one of the better designed stock systems in modern cars. The main bottleneck that the RA has, imo, is its tiny blowdryer of a turbo. There's nothing wrong with a small turbo for city driving though, I don't personally plan on upgrading the turbo any time soon.
