 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.
