Purchased this K&N air filter for my daughters car that we purchased for her. Did so to avoid her from ever having to buy an air filter for it. Have K&N air filters on 86 Porsche 944, 99 Chrysler 300 & 2007 Saturn Outlook XR. That says it all.

Noticed the difference in my 2007 Pontiac G5. Very happy with my purchase.

The K&N filter provides better air intake thus leading to better air to gas mixure. At low rpm I am able now to shift my first gear in position witch before was a delicate thing to do and often had an awfull metal grinding noise. With a solid service of the injectors/air docks/intake manifold combined with the K&N filter I get more then satisfying engine performance. Very good product and very good engenering work. I recommend this product every time I can at the Canadian Tire Services Center where I work as technical advisor.
