Fits great, good upgrade over stock, wakes truck up,

Fit right in and works good.

Great product for price

Great air filter surface volume. Their filter kit is great as well. I usually cut the pipe a little short if using the stock outlet hose from the filter to the ccv ring.

I replaced my spectra cold air intake with this filter,tired of maintaining and oiling,,this filter is an improvement,will continue to use this filter think engine breathes better,easy install with a 4in.exaust pipe which local shop gave me..will continue to buy parts from riffraff.

Purchased this filter for my Ford F250 for years. Unfortunately I sent this order back because my truck was totaled.

Good product, much better than stock on my 97 f250 PS.

Removed the K&N after reading flow and filter performance tests. This filter will not fit in the stock air box!! 2001 F 250 BUT it will let your engine breath with the Best filtering performance. The washables are all junk, pure hype.

Every 7.3 should be running these. You should also buy these from RiffRaff because Napa charges 65 bucks for the same filter. Plus why not but from a great company that supports all us diesel bros.
