The air cleaner on my s2000 used to get filthy in no time at all due to the ram air set up, this keeps it cleaner for longer and is super easy to use

Buen producto como todo lo original K&N, el env?o lleg? antes dem tiempo estimado. Feliz con la compra.

Highly reccomend for cold air intakes!

I love how well this sock worked for me. I have a supercharged 2007 Pontiac Vibe and I installed heat extractor vents that would expose my SRI to rain and other elements so I wanted it to be protected and this worked perfect. Washed the car today and the filter was perfectly dry with the exception of a few drops sitting on top of it!

Fits my 2015 HD Streetbob's Screaming Eagle big air intake perfectly.

Lo instale como precauci?n a mi filtro kyn

This fit really good on my K&N RU-4740 filter. Great product.

As advertised. Works very well
