5.0 out of 5 stars Better air flow and acceleration!, May 23, 2007

After replacing my stock air filter with the K & N I did notice better acceleration through the gears, along with slightly increased gas mileage. Also, I think the price compares to about 2-3 regular air filters, so it pays for itself anyway after only a few years. Add this to the mileage you gain and it's a rockin' good deal!

It is my third K&N filter that I am purchasing for my cars. It works all the time, it does increase torque and milage of my cars, even it barely 5-10% increase but for the this price and fact that you can skip 2-3 regular air filter's replacement intervals it is great result. I do not restore or clean them, after 40-50k miles I just install new one. Time spent on cleaning and oiling it worth for me more than new filter.

Do not forget to put K&N sticker on air filter box to stop service man in his best efforts to up-sale you for a piece of junk that he had on shelf of his garage.

First, this filter will NOT give you huge horsepower gains, it might give you minimal MPG gains just by replacing the filter from a dirty, clogged one, but that will come with any filter. I bought this filter because it does save money, money you would be spending buying paper filters over and over again, with this and a 10-15 dollar service kit, this filter will last your vehicles lifetime. There is a trade off though, this filter does not screen out dirt as well as say a "paper" or foam type filter, that is why "off roading" voids the damage warranty. however i never off road, and for highway and street use, this filter is King in terms of economy and durability (it is made of 4-5 layers of cotton encased with a aluminum wire mesh surrounded by hand poured urethane), they mean it when they say it will last a Million miles. This filter earns my recommendation.
