K&N 33-2473 Air Filter Product Reviews

Everything has gone smoothly. The purchase process was seamless, and the product is exactly as expected.

I purchased the filter as an upgrade, as not to void my factory warranty. It was easy to install and amazingly half the thickness. I've noticed an increase in responsiveness and power. Wouldn't have believed a filter could do this. My wheels now break loose at 5000 rpm in first gear. Will recommend it to anyone looking for a inexpensive upgrade. Thanks K&N

I've been using K&N products since 2000 on all of my vehicles. I'm very happy with my filter purchase. Saves me in gas money and air filter buying money. Purchase the cleaning kit if you have not already to recharge the filter at 50k miles.
