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.

I've had this for two weeks and have noticed an uptick of .2 mpg. I bought this for its because it's reusable mainly. I would recommend buying one if you plan on keeping your car for the next 3 years or more. It should pay for itself by then vs the cost of disposable ones. Also only needs to be cleaned every 50k according to manufacturer specs.

I am very pleased with this filter. I can not notice any performance issues, but I never have to buy another airfilter again!

I have always used K&N filters in my Mustangs and always saw an improvement in power. It's been a month now since I put one in my 2008 Ford Escape and I'm glad I did. I'm getting a noticeable improvement in power and an extra 1 1/2 to 2 miles per gallon on average. These filters are worth the money paid and I would recommend them to anyone.

Make no mistake, K & N filters are top notch, but beware of people who claim huge improvements in mileage and power (i.e. 10-15%). With the billions of dollars the auto industry has spent trying to improve gas mileage and power, every car made in the world would have these as original equipment if such gains were possible. If life were only so simple. People who replace a CLOGGED filter with a new one will notice an improvement (if it's clogged badly enough, the improvement might be that your car runs now). Definitely better than many in fit and quality, plus being reusable, but a magic bullet it is not. A clogged K & N filter will also cause performance problems, it's just that all you have to do is clean it properly, and you are off and running; whereas a paper filter, you have to throw it out.

I have to admit that I was a skeptic. However, the price for the K&N was close to the inflated dealer OEM price. I have noticed increased HP and better fuel efficiency on my Toyota Sequoia. It is hard to quantify but I liked the results enough to buy another filter for our other vehicle. Shipping was very fast and product was well packaged. I would definitely purchase again... and I did.

Replaced standard air filter in a 2004 Nissan Frontier Crew Cab V6 5-Speed - Consistently get 20 MPG (High end for rated Mfg MPG) for combo city/hwy driving, and I do not drive conservatively. I do not have previous data, as I just bought truck (Used). Great throttle response. K&N have a superior reputation. Amazon saved me approx. $15.00 over local auto stores.

Just purchased it about 2 weeks ago, will need more time, but there are noticable differences: Alittle more noticable horsepower when I needed it and my gas mileage went up, meaning less time at the gas station! Worth the purchase!
