K&N RF-1020 Universal Clamp-On Air Filter Product Reviews

I have two of these for my 2005 F150 Lariat. Reason is that when I clean and re oil one I let it sit in a plastic bag to let the oil seep through so as to not contaminate the MAF module. This way the excess oil can drain from the filter. This method allows me to drive the vehicle without having to wait for a filter to dry before using it. I use K&N oil filters with Schaeffer Oil in my truck as well as my HD Road King.

This product is extremely high quality and added a noticeable increase in power combined with my cat back exhaust system. This filter replaced a cheaper similar designed product from a different manufacturer. My 2000 SIlverado has 250,200 miles and runs fantastic, the motor loves to breathe and this RF-1020 does a great job.

I am very satisfied with the service and support received, when I thought it was going to be a difficult task since I didn't have any information regarding the existing filter. Just some general data and a picture was enough for your staff to determine the right product. Not to mention the convenience of receiving it at my door step. Thank you so much for your support.

This order was actually 5 stars but my total experience wasn't. I originally ordered based on year, make and model of my truck but that filter didn't fit, so I had to return it at my expense. I then realized I had to measure to get the right one. From that point all was good. I just felt there should have been some caution that the original order might not work and that I should confirm by measuring.

Did not have any spec's on old filter that was already installed on truck. After getting some measurements off the old one I found one here at K&N that was a perfect fit and actually cheaper than other brands. I'm very pleased with product and will continue to buy stuff here. And the shipping was easy and very fast.
