 Good product and keeps the filter clean. The elastic on both ends stretches after a year or so making for a loose fit. I purchased this product as a replacement for a wrap that had lost all elasticity.

 Upon first buying the aftermarket intake along with a turbo back exhaust, I gained almost 5 miles per gallon. I used the first filter for 10 years and only replaced it because of the dents I put in the screen. I wouldn't consider any other filter on my Dodge Diesel Truck. Thank You.

 Love this filter on my truck. I bought an extra one so I can switch without having to wait after cleaning. Now I always have a clean one ready to go.
