Recently purchased a 2006 V6 4 Runner Sport Edition. Love the
truck but gas mileage and engine performance were just ok. I was getting
18.5 to 19.5 in town if I was careful. Just installed the K & N Air
Charger System. I'm not a great mechanic but still found it relatively
simple with your directions. It's hard for me to believe but gas mileage
has increased to 23.5 to 24 if I can keep my foot out of it. Love the
engine sound. Everything about the vehicle is smoother and with the price
of gas this will pay for itself in no time. The truck is quicker off the
start and pulls much harder all the way through the power band.
You guys claim an increase of 9.5 HP but the seat of my pants say your selling
yourself short. Love the product.

My friend who races go carts advised me on the K&N oil filters. This will be my second oil change using them on my 2006 Toyota 4 Runner. I can't tell how they are working but I trust my friend and will be using the K&N oil filters from now on.

When I heard about K & N filters I was a bit skeptical. I first got my mechanic's opinion before making a purchase. Bottom line was that it cost $22 more initially than a standard Toyota air filter, but I was banking on the longevity of the filter to be a good investment. I usually drive my vehicles about 200,000 miles before a new purchase.
We just returned from a five state, 3,273 mile road trip. I drive a 2005 Toyota 4 Runner and never got over 20.9 MPG before my K & N install. On this trip I got up to 24.3 MPG, but never less than 22.5 MPG. Overall average was about 23.5 MPG. In effect the filter has already paid for itself, and I am confident that this will be the last filter I need to buy for this vehicle. Good for me and good for the environment.
My only regret? I didn't do this sooner. Any plans for the future? Yep! I'll be buying K & Ns for my other vehicles....
