Best easy modification I can do to my 7.3 power stroke. Riffraff makes it easy with their kit. Best investment ever.
I've been purchasing from Riffraff for a while now for my 7.3 powerstroke and I can truly say that their prices are reasonable. Every time I order from them I receive my product within a reasonable time. I will be their loyal customer.

Badass Filter
I know you're thinking will paper filter really be worth it? Guess what it is, throttle response difference is immense. I bought one for both a 2002 and 95 Powerstrokes and both showed amazing results. Riffraff coming in clutch as always!

Want your 7.3 to breathe?
I was very Hesitant to install this since I have had nothing but good things with the stock air box. My friend has the same year 94.5 and said he could feel and hear the difference so I had to try it out. Went out and got a 45 degree bent black PVC adapter from The hardware store to match up with the stock intake tube and fit perfect. I can feel the difference in throttle response and my whicked wheel sounds amazing. It’s a must to let your 7.3 breathe. Shipping is always fast and Reliable. Thank you riffraff!

6637 Donaldson air filter
This is about the best price I have found for this filter. Napa is twice the price. It is also a good upgrade from stock with better flow and better protection than the oiled K&N garbage.

Best Price
I have run these Donaldsons for almost 10 years now, and this is by far the best price I can find on them. Had tracking in 2 hours of ordering. Keep up the good work.
