This is our 2nd K&N air filter. The first one is for our 2010 Toyota Tundra 4X4 with the 5.7 liter V-8. After installing 3 dual exhaust & the K&N air filter, my truck now pumps out over 400 h.p. The gas mileage didn't increase, but it will pass anything in record time. I recently purchased another K&N air filter for our 2011 Toyota RAV4 with the 3.5 liter V-6, 4X4. It was pretty quick before the K&N, but now it is quicker and gets 2 mpg. than before. I will be ordering another K&N filter for my wife's Camry as well. For anyone that is considering buying a K&N air filter for their cars / pickups or motor homes, I would highly recommend K&N. They make great Christmas or birthday gifts for family and friends.

Power transfer is quicker & tighter, less hesitation on gear shifts, engine is running at a cooler operating temp and gas mileage is consistently running at its advertised maximum. Have had the filter in for about 6,500 miles now and of course have noticed no indication of dirty air filter performance loss where a normal air filter at this point would have. I may have noticed some minor hesitations, especially living in high altitude Colorado mountains where dust & dry air chew through filters! When I do get to clean the filter for the first time I am excited to see its lifetime qualities put into action!

I've used K&N products for 20 years and no problems. They perform as described, that is why I'll keep using them. Great product.
