Very hard to install (extremely tight fit over the aFe Big Boost filter). Otherwise satisfied.

Awesome , well built , easy to stall over filter

I replaced my old Riff Raff 6637 cover due to a couple of small holes from a few years of service. This cover is made from a completely different material than my old one, similar to the water resistant one tucked behind the inner fender well in my KB Supercharged Mustang. This should work well due to the modified air intake chute on my F250 that may allow rainwater to blow towards the air filter driving during a heavy downpour. Time will tell how it helps protect the paper-based 6637 elements over my one year maintenance annual change out.

Definitely helps out, and prolonged the life of my filter. I also noticed that water beads of quickly instead of being directly absorbed into the filter, noticed while cleaning my truck after opening the hood a little water had dripped off the hood onto the filter, not saying its water proof by any means but its better than having a completely exposed filter on your intake set up

Quick, easy install. USA Made, and really helps extend the service intervals on my filter.

This was the 2nd time I purchase this item, the first one was very durable and fit well over the filter the second one I received was cheap and seemed of lower-quality.

Ripped when installing over the filter. Cheap thin material doesn’t stand a chance going over the metals filter grates.

Good and snug on the filter

This is just what I needed for my 7.3. Keeps bugs and bigger debris from getting sucked into the filter. Thank you.
