my friend told me that if he uses just regular pipe(like exhaust piping) for his cold air intake tube its the same as buying a KN tube made for cold air intake? is he right?
No not really, cold air intakes use thin aluminum, saves weight and does not rust. Exhaust piping if not stainless steel. Will rust. And looks like crap. If you want to be cheap and dont care it will work though. And so will any other type of piping.
very confusing situation. check out at yahoo or google. that will might help!
I'm going to assume you put the intake filter in the engine bay. They don't really work all that well. The only real way you see a performance increase is when you get the intake that you feed through the side wall under the fender. If you want even better performance, you get rid of the wheel well and install a 90 degree angle cover around the cone filter and you'll increase your power band in the higher rpm region. The only problem with having the intake feed underneath the fender without the wheel well is you expose some wires, vaccum line sensors, and you cant drive in the rain for too long or you'll suck up too much water. You'll have a water injected car if you drive in light rain and make some serious power but too much water will have you bend a valve and/or flood the car. Its the way I have my 99 cobra setup and I ride along side 02 ws6 trans ams and beat them in the rain!!! I've done it so I know!!!
