FILTERWEARSPre-Filter F104K For Napa 6637 Donaldson B085011 Baldwin PA2818 Fleetguard AH1141 Fram CA6818 Wix 46637; BLACK

I recently purchased the FILTERWEARS Pre-Filter F104K for my air filter and have been extremely satisfied with my purchase. The pre-filter is easy to install and fits securely over my air filter, providing an extra layer of protection.One of the things that I love most about the FILTERWEARS Pre-Filter is that it extends the life of my air filter. It captures larger debris and dirt particles before they can reach the main filter, which means that I don't have to replace my air filter as frequently.The pre-filter is also very durable and easy to clean. It is made of high-quality materials that can withstand harsh conditions and is resistant to water and UV light.Overall, I highly recommend the FILTERWEARS Pre-Filter F104K to anyone looking to extend the life of their air filter and protect their engine. It is a simple and effective way to improve the performance and longevity of your vehicle.

I have the AFE washable filter in my 99 F350 7.3 diesel. The cover I got from Riff raff diesel does not cover the front of the cover, but does help keep the main body of the filter cleaner. It was time to clean the filter and look for something that more fully covers the front of the filer.Works great, Snug fit, and helps keep the top of the filer clean as well as the main body. Will likely add another to the pack.I like high flow filters, but have always added some type of cover for added filtration as well as protection of the engine.Very nice.

It fits over the large generator filter and helps with larger debris from clogging the main filter.Does a great job! I recommend for all air filters to have one if possible.

The media could not be loaded. Love it, love it looks good! 🤣🤷‍♂️

Fits filter snug and keeps smaller particles out as described. Would buy again.

Perfect fit!!!

Fit my 6637 knockoff filter very well. The red looks real good with black engine bay. Would buy again.

Was gonna order a riffraff cover for around the same price but the website charged my card thru PayPal while I was still tryin to set it all up and I hadn't had a chance to make an account or enter my address or email yet so I bought this one on here instead, had more colors to choose from and same if not better quality plus it came with 2 free stickers.
