Tech Notes
To clean the filter, first brush off any large embedded dirt. Then spray on the K&N cleaner and let it soak for 10 minutes. Next, Rinse off the element with LOW pressure water. (Always flush from the clean side to the dirty side.) Then allow filter to dry NATURALLY. After filter has dried re-oil with K&N air filter oil only. Apply evenly to entire filter making sure to oil down into each pleat. Then re-install making sure the element seats properly in the filter case.
Description
K&N developed and manufactures a high-flow, washable filter that has been proven, again and again, to increase an engines performance. Oiled premium cotton gauze keeps dirt and debris on the outside of the filter to improve filtering efficiency. Hence, dust and dirt will not clog the filter element as quickly as it will paper and foam. The accordion fold design provides up to five times the filtering surface of non-pleated filters. You won't have to worry about moisture either, since it will not clog the oil-saturated element. Even after being completely wet, the filter won't need to be replaced. The cotton filter media is protected by an epoxy coated aluminum screen mesh that also straightens the air flow for increased air flow. K&N filters are easily cleaned and are backed by a Million Mile Limited Warranty.

1 out of 5 stars No difference with K&N

Have noticed no difference in either the performance or mileage. Might have even seen a decrease in mileage, and if that is confirmed, I will be going back to the stock GM filter. Maybe the K&N cold air intake system is a better choice. Sorry, but I can not recommend just the filter.
5 out of 5 stars Great Value, Cheap Horse Power, Great Gas Mileage!

These K-N Filters are a great value and Performance Center sells them for almost half the price of my local auto parts store. With these filters you get a life time filter, HP gains over a stock filter and increase fuel mileage plus your car just runs better. This all adds up to a GREAT VALUE!

Replaced air filter w/ K&N lifetime filter element.Installation was so simple, less than 5 mins. Already noticed an increase in speed vs. rpm. Also noted an increase in fuel milage of approx. 1+ mpg.and have only had the product for 2 weeks in my 2002 chevy truck. Better air flow DOES make a difference!!! Would recomend this product to anyone. AAA+++
5 out of 5 stars Just what I expected

Using this on a 2007 Yukon XL and gained 1.5 miles per gallon. I have always put the K&N air filters in all my vehicles. Just makes sense over the long haul. Pay for it once get better gas milage and then just clean it 3 times a year. It pays for itself within one year.
2 out of 5 stars bad milage

I am very disappointed in the Two (2) k&N air filters i recently purchased. The fuel milage on both viehcles dropped by (2) two miles per gallon. i have not changed my driving habits nor has my wife. I will give them a few more miles of driving to see if it improves,oterwise i wiil be returning them for a refund. thank you. ALAN ----------

I bought the K&N air filter to replace the stock filter in my 2001 Chevy Silverado. I have not noticed any increase in gas mileage as K&N so proudly boasts about. Although it hasnt increased my mileage I will enjoy not having to replace it and it was an easy install.

This filter has definitely given my ride more horsepower. It seems to run much smoother and shifts even better than before. I will definetely recommend this product to every one I know.

Did not notice any difference from the stock filter. Thought I would get 5-10 more HP, and a couple of mile a gallon better, but have not seen any change.
