My Car is a 1999 Honda Accord with 221,000 miles. (Seriously No Joke) First: I noticed an immediate improvement to the responsiveness of my accelerator. The car felt like it just got 7th piston installed. The responsiveness is an awesome feeling in this old ride. Second: And to me the most important is the unbelievable increase in gas milage. I'm totally serious and being truthful here. I've driven the same route to and from work for over 1 year now. And have always used a full tank of gas by Friday evening. My milage for a full tank was always 290 miles to 300 miles. With the K&N Air Filter installed for the last month I've been getting 325-335 mpg. This is unreal for a air filter to improve my car this much. But its NO Joke. Gas milage is way up This K&N Air Filter will pay for its self in just a few more fill ups. I'm not getting payed for this review. Its mandatory for me to pass on the good news to whoever reads this. I could not be happier. Thank you K&N so very much for a phenomenal product. Brian Darnell

First off I have a 1999 Honda Accord V6 with 220,000 miles. Now this car has only received standard air filters until I bought a K&N 33-2133. I've now run 3 full tanks of gas in it. I noticed the first day that the responsiveness of the accelerator was AWESOME. It just feels like its quicker and smoother and maybe it truly is. I've also notice a 30mpg increase in my fuel economy! Give me a few more fill ups and the filter will have paid for itself. I can't believe something so simple has made such a tremendous difference in my old Accord. I can't state enough how impressed I am and am loving the new feel of my car. Thank you very much. -Brian Darnell

Always the perfect product for the application, K&N has always been my choice for reusable airfilters. Easy to maintain, and saves money at the same time. You will not be disappointed if you purchase a K&N filter. I would recommend these filters to anyone considering a change. Fast shipping and a vast selection of filters for whatever vehicle you're needing a filter for.
