    Open her up and let her breathe !!!!

    This filter combined with caty delete and down pipe is perhaps the most cost efective and easist way to pick quicker turbo spooling , lower EGT's better fuel milage ( assuming you can keep you foot out of it ) noticeable HP and torque gains too but not measured

    Buy 2

    Great filter, use with a cover to compliment your engine area.
    Buy 2 at a time, as your shipping charge will be about the same.

    I have been relying on this filter for years and it continues to deliver. Good pricing and fast customer service to get it out the door for shipment.

    Best filter option, hands down.

    Huge filter, plus fine particulate protection, equals great flow and great protection. Don't dust your motor from a K&N like my buddy did. This flows just as well, if not better and there is no worry about having to rebuild a motor or turbo!
