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

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.

Ordered a filter about a year ago and couldnt be happier. Great product, awesome customer service at an affordable price! Highly recommended!

All I run on my 2002 7.3 PSD. Heck, I buy'em two at a time........ Well made product!!!!!

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.

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!

When I ordered my first filter about three or four years ago for my 7.3 PSD, it did not have an inner metal mesh which I understand is important for catching pieces of the paper element in the event of a failure. The new filter has that mesh and I was very happy to see that. I installed this filter with the Riffraff cover on my father's 5.9 so I could chuckle whenever I opened the hood and saw one of Clay's logos on a Cummins.

Good product at the best price and super fast shipping from the Riff Raff Crew

Excellent air flow, long life, and cost efficient
