Air Intake kills wrx turbos?

Aight guys this time i need some big defense...My dad doesnt want me to get an air intake system because he feels that my turbo will blow and that theyre not good for forced induction engines...now i already know about how they can suck more air through your stock up-pipe and break down the catalytic converter and send it through your turbo, permanently destroying it...Ive taken this into consideration already and have upgraded to a TurboXS up-pipe without a cat...
Help me out and let me know what will happen (if anything negative) to my scooby if i put an AEM or a K&N intake in.
Thanks.

I've never heard of an intake "killing" a turbo so to speak.

Yeh well that can happen becuz of where the cat is in the up-pipe, this guy i know had a wrx and before he knew about that problem he put an intake in and he ended up ruining his turbo because the broken up cat went through it...so you just got to be careful with them

wa wa what

:eek: hey big joe, that cat going through your buddies turbo sounds like it was a cat problem rather than him putting on an intake. The question is though if your looking for more power or just sound? cause the intake will do nothing but make it sound nice slightly! Why not take that money and by an downpipe instead? far more more beneficial, don't you think?

DONT BOTHER WITH AN INTAKE!!!

The stock air box is good for 350hp. When you add an aftermarket intake it throws off the MAF and cause the car poorly. Stay with the stock box! Also don't bother with the BOV.

Umm..... where to start?

Intakes don't suck air through your uppipe. The uppipe has nothing to do with your intake system. And, they have no effect on your cat.

They do, however, have a negative effect on performance. But, it is a design flaw that makes them bad, not the extra airflow.

you can run a short ram system with out any adverse affects. there will be zero performance gains, but it can be done. whatever you do make sure that you stay away from an intake that has any sort of bend between the filter and the MAF.

wow, 5 same posts. it seems unanamous. CAI are not for these cars.. !Laugh! .
If youre friends turbo "sucked up" some cat contents he probably raised the boost while stockish. That will do it b4 anything else!
Get a down pipe and e.m.. Tell you pop it will help you get better mpg !Laugh! . Then tell him you want a bigger turbo, injectors, cat back, radio ( a must).......

... if he installs a CAI, he will not notice any power gains. I don't care if you're God, it's physics; the most you'll ever see is 3hp, if you're lucky. Further, you can get that same sound by removing the intake resonator, and it will cost him nothing.

I believe he's refering to the CAI. ... fine, don't listen to us. Go buy it.
