Easy to place order. Filters arrived when scheduled. Installation was easy as filters were exact replacements for stock. This is third car I have ordered K&N filters for. Good product.

Great service, quick shipping, took about 30 minutes to install, remember it is on a Mercedes SL550. I am a long distance driver, over 100 miles per day, and a mileage nut. Will let you know what happens with mileage, but throttle response is noticeably quicker, I can hear the engine more when I accelerate. Wish you guys had a cold air intake for this monster...I guess its a very limited market.
