Product Reviews

  I purchased this wrap to protect my filter from sand getting into the filter and does a great job of it too. Also extends the amount of time before needing a cleaning. Most of the time you can just pull off the wrap and shake it off or rinse it off and get back to business. I do wish that the elastic was tighter and would snug itself around the filter a little better. Overall a great addition to my trucks performance.

  Part was as presented on the internet, specifications etc. Everything went fine on the Installation and my truck definitely runs better.

  Bought my first one in 1997 when my Expedition was new. 17 years and 150,000 miles later, just now having to replace it. Need I say more? :)

  I installed the RF-1020 on my new (at the time) 2005 F-350 Harley Davidson Edition with the 6.0 diesel. The fuel mileage went up by 1.5 miles per gallon after installing the kit. Now with 352,500 miles on the truck it averages 19 MPG on the highway and still has the original RF-1020 on it. I clean and oil the filter regularly and I expect it to last forever. The chrome cover fell off the filter almost immediately but that didn't seem to make difference in performance. Thank you for a great product!

  Happy with my filter. I had to buy this one to replace my original one because it had a hole in it. You guys make a great product.
