I am looking at a wrx thaat is stage 2 cobb ots map 91 oct but it has an injen cai on it. i have read about the lean condition that this creates, and am a little woried about engine damage as the car was driven with this intake. are my worries warranted or am i just paraniod?
its not great, but i think being reflashed to stage 2 makes it a little better. How many miles on the car, for how long did it have the cai?
not too long i dont think. within 5k miles would a hacked stock airbox make the same spool sound and still retain laminar flow over the maf?
5k miles should do noting to the car at all. And yes you can get plenty of sound with stock airbox and no silencer. You can always get K&N short ram or anyother short ram intake, but you will get a lot of heatsoak. I would stick with stock airbox and stock filter aswell.
I run a k&n typhoon short ram intake and it is just fine as far as idling and power wise. There is a lot of people that will try to scare you out of buying an intake for your wrx but I say the hell with em'!
Yeah, to hell with all the research and lessons learned from the community over the past 6 years. Nevermind the FACT that intakes can cause lean conditions due to improper airflow over the MAF sensor causing skewed readings sent to the ECU...you know, the computer that controls all the vitals to your engine such as fuel control and ignition timing, and short ram intakes on otherwise stock cars (stage 2 included) cause heatsoak, take in hot air from the engine-bay and otherwise retard performance. You just piss the wealth of information and facts and just do your thing, bro. To hell with 'em :roll:
^^^ The K&N typhoon short ram intake is the one The K&N typhoon cai, I believe, goes with the Injen & AEM
For the MAF to function properly, airflow across it must be smooth, steady, and following a straight path. High turbulence can cause erratic voltage readings from the MAF. If and when turbulence occurs, then the ECU cannot accurately determine how much air is entering the engine and how much fuel to mix with the air.. Taking the chance for a somewhat minimal power increase to possibly ruin your engine from running lean. Why take the chance..this is my opinion but research damn well backs it up.
stock airbox with aftermarket filter is the ONLY way to go IMHO, unless you are pushing for higher horsepower(like upper 300's which no stage two will get you even remotely close too)keep the stock airbox(or i have an spt shortram that came with my car for sale
