K&N RF-1045 Universal Clamp-On Air Filter Product Reviews

Wednesday, January 23, 2019 - Part RF-1045
I have an '06 Jeep TJ with just over 100,000 miles on it. I installed a K & N RF-1045 filter shortly after buying the Jeep 12 years ago. I have washed and cleaned the air filter many times since but lately the filter just got old. My Jeep was getting 13 - 14 miles per gallon and a lot less when plowing snow lately so I purchased a new RF-1045 filter and installed it. My Jeep's gas milage has jumped up to 17 MPG. At the price of gas, I will recoup the money I spent on the new filter very quickly. The engine is running cooler and smoother now and has a noticeable better get up and go. Best filter system ever. Thank you.
