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.

"Installed the new K&N filter Sept 23 2008. There is not any noticable difference in horse power but I don't generally run up the RPM's to those levels. The MPG has actually increased about 1.5 MPG's from the last tank to this tank. No change in the type of driving 25% city 75% hwy/interstate. The MPG increase might be because the factory filter was ready to be changed and not all because of the easy flow of the K&N but I will take any increase I can get. Autoanything is a great place to buy the filter. They promptly processed the order and I had it in about 4 days from the time I ordered it. I had no issues with installing the filter into the factory box it fit just like a new paper one would. I would recommend this filter to anyone looking for a permanent filter for their vehicle(s)."

"Installed air filter for my Dodge 3500 Diesel. After 1800 miles I have surmized that the air intake is better. It may be giving me a bit more power,but it's hard to tell without putting it on a Dino. Fuel consumption is the same as before. Not much change from the OEM except quality and of course and not having to purchase new filters all the time. Works great in my bike gave me extra mileage and pep. Thanks for a great product"

"I installed this filter about 2 weeks ago. I have yet to determine if my MPG has improved, I will find out on my road trip to the mountains next month. I have noticed the engine seems to breathe a little easier and accelerates a little quicker. At first I thought it was in my head but time has passed and I no longer think that. I would reccomend buying one. I paid $42 for mine and it will have paid for itself after 2 regular air filter replacements."

"An excellent product. But difficult to install. I had it installed on my 2007 Toyota Avalon. I have changed many Air Filters on Cars and have done minor tuneups on a twin engine boats that I have owned, but this installation was extremely difficult. I had a Mechanic do it for me. Trouble is Housing on this car does not make it easy to install these filters or any filter for that matter."

"Bought this to replace the standard on my nissan armada due to the fact I never need to buy another again, just clean it when needed. The throttle response has greatly improved, it feels more powerful and the fuel mileage has increased by 10% consistantly meaning a saving of $8 a tankful so taking off the cost of the standard filter replacement cost of $16 the filter has paid for itself in 4 tanks of gas!! This last tankfull returned 19.1mpg and I do not drive slowly."
