ive talked to chevy service department, he said they do not recommend k&n products because of the oil in it, i had one in 5 diff. vehicles and never had a problem. K&N says it will not hurt a chevy and stand behind there warranty policy. So my question is why does chevy seem so against K&N or any oil based filters, or air intake product. I also asked if they recommended air intake systems and they said they did but it was the ones made by GM , but they dont make anything for the cruze! So whats your thoughts?

The "correct" answer really depends on your driving environment. I personally saw the intake tract of Duramax engine pickups (stock and K&N) that ran the GM air filter test in Arizona. Huge difference in how much superfine matl gets in there.

OTOH I knew a guy who ran a 283 Chevy in Cleveland Oh for 100,000 miles with NO air cleaner at all, and it ran fine. That's an environment with a lot of rain/snow, little dust, and he ran 100% on paved roads.
