Description

For more than 30 years, K&N Filters have been the choice in engine filtration. The K&N filter delivers virtually unrestricted flow letting your engine run stronger, cleaner and with greater fuel efficiency.

The secret of the K&N filter is its filter medium. Four to six sheets of pleated and oiled cotton-gauze are layered between two sheets of aluminum wire mesh. This proven design stops dirt, dust and other harmful particles like no other filter, all while clean, power-enhancing air flows freely to your engine.

Just give it a simple cleaning every 50,000 miles and your K&N filter will last for the life of your vehicle. With no costly changes and services, your K&N filter will save you money. And, you'll be helping the environment by reducing the number of disposable air filters that end up in landfills.

Get increased power and acceleration, better fuel economy from a filter that lasts for 1,000,000 miles-get a K&N.

"I've been using K & N Filters for many years now and have used them on cars and pickups alike with great results. I've seen an increase in horsepower and economy with their use. With the K & N Maintenance kit, you have the cleaner and oil to maintain your filter and never buy another filter for your car, truck or SUV."

"Since installing this filter I have noticed about 10% improved mileage, and noticable throttle response immediately. For the price, it's a simple change that's more than worth the money. Going to put one in my wife's vehicle right away"

Gas mileage up 10%

"I read online that a performacne air filter could improve gas mileage. A few car-mechanic forums seemed to confirm it and I saw K&N mentioned a lot. K&N had a stock filter that would fit my Honda Accord without any modifaction, so I bought one for $38 with free shipping. I had already measured my car's gas mileage with the old filter. After 300+ miles, or highway, small road, AC running,a nd AC off, it got 23.# mpg. As soon as I installed the K&N air filter, I reset the trip odometer, and after 250 miles, it measured out to getting 25.7 mpg. 10% more. At 10%, this $40 filter will pay itself off after $400 gallons of gas. or about 2,400 miles for my car's mpg. I figure I probably drive that distance in 2 months (thanks to having no work commute). So after that time the filter will have paid itself off, and my car will get an extra 30 miles of driving from each tank of gas. A few other factors.. the future cost of air filter oil when I clean and re-oil the filter. the benefit of the engine getting more air for it's 'health' The filter was easy to instal and took a few minutes. Pop the hood, unscrew 4 screws, remove old filter, put in new filter, screw the screws back, close the hood. I'm recommending perfomrance air filters to all my friends and family. For anyone who'll have their vehicle for longer than a 1-3 months, a $40 performance filter will result in a savings in gas cost."

"K&N Filters are excellent quality. The element arrives pre-oiled, so you just drop it in and go - does not get much easier. A K&N should be the first step for almost any performance modification project."

Fuel mileage improvement on my 07 Ridgeline

"First tank after replacing my factory air filter, some 17,000 miles aged, I increased my mileage from 18.8 mpg to over 22!!!!!!!!!!! Actually, I then increased tire pressure from 32 psig to 38-40 and boosted mileage to an unbelievable 25 mpg. So, I owe all this future savings (and with the price of gas currently at $4.27 per gal and rising), I need every advantage I can get. I subsequently purchased a K&N air filter for my wife's Vibe, as well. BUY A $50 K&N and save $20+ per month!!!"

"I didn't believe the air filter can make such different before I actually install it to my 3.0 Liter V6 2000 Honda Accord. It's great, I can feel the power boost right after the installation. You can feel the power when you hit the gas, and it picks up faster than it used to be. Go get it if you don't mind your car going faster!!"

K&N Air Filter for My Ford Escape

"Firstly, I was very happy to see that K&N made a replacement element for the OEM air filter for my Ford Escape, V6. The cost was a lot more reasonable than if I had to also purchase an entire air filtering system. I was familiar with K&N given that I have purchased in the past for motorcycles, but never got one for a car. I was happy that they made one for my car, since K&N made a "lifetime" cleanable filter and I would not have to keep buying them. The instructions were SUPER and made the installation a snap, much easier than if I had to figure out how to do this myself. Mel "
