4.0 out of 5 stars Smoother power curve, at the cost of being harder to clean, April 19, 2011

This review is from: K&N E-0945 High Performance Replacement Air Filter (Misc.)

I waited until my F-150 had 125,000 miles on it to get the K&N filter for it and now wish I had bought it sooner. The engine response on acceleration improved noticeably, while gas mileage only improved very fractionally. I like it a lot, but understand that cleaning and re-oiling it will not only be a chore when the time comes, but it might also be a bit pricey (almost as much as the original filter.) Considering this costs about 2x what an air filter at Jiffy-Lube costs, maybe that's ok, and I'll reserve judgment until I've actually done the cleaning and re-oiling once. In the meantime, I have smoother, quicker acceleration, and I'm pleased. I used 4-stars instead of 5 because of the cost/work of cleaning....

This review is from: K&N E-0945 High Performance Replacement Air Filter (Misc.)

I've had my K&N air filter for my F-150 4.6L engine for 3 years now, and it continues to perform above expectations. Even the cleaning process is a snap, and gives me reassurance that I will continue to get a lot more life out of it. What I like the most about this product is its almost immediate results when it comes to acceleration (though I'm not really into stepping on it these days), as well as the 11% fuel savings I generate on the highway; I have proven this time and time again for the same 232 mile jaunt. This air filter has put money in my pocket over the years. I highly recommend this product, especially in the new era of high gas prices and price-gouging.
