I got this for my Tacoma 4 cylinder pick-up truck. While I would not describe the acceleration on the truck as zippy the K&N filter does add a noticeable gain in power, particularly when going up long inclines.

Performance seems to be better. Don't know about gas mileage yet. Would buy again and recommend to everyone.

Works just as promised.
