Car Modifications Is This Ok?

[grumpee]

Hi there, just some queries i have some of my car mods. SO far, i have changed my air filter to a KNN unit, but i have a GREDDY TRUST AIRINX2 ready to go in. But my friend tells me that during wet weather, there will be forced cold air induction and my engine might blow as a result. What are the risks of this happening in a 94 TEG VTIR? What are the risks of a foam filter? Now, i drive my car everyday and melbourne is QUITE wet n cold. So i have a couple of options:

1) Go with the KNN(just the pod)
2) Change the air filter in the ORIGINAL BOX to a KNN
3) Use the GREDDY TRUST AIRINX2 filter (foam)

Also, can anyone recommend me a good exhaust system. I was thinking about APEXI n1 SYstem. ANd shockers, i was looking at KYB. Camshafts (type r or toda). I want to optimise power in my NA car. Please let me know. THANKS ALL!

What about COLD AIR INTAKE? Is this BETTER THAN the aforementioned mods? Not many people here in australia know much bout cold air intake n neither is it readily available here. Just want to know if the power gains are worth me importing one from the states. Or will a KNN or GREDDY item do the same thing? Thanks all

The blowing your engine is what the CAi will do. That picks upa cold air feed from somewhere lower on the car (usually front bumper or front guard) and feeds it to the filter. Either of the performance filters you have are fine. For laziness sake, I'd just leave the K&N.
