Eemeli, Finland
The product works well and has improved intake sound. Was more snug into the air filter box than the original filter, so it seals well. The included stickers are a nice thing to have too.
Ethan, Sydney, Australia
Very happy! Postage was quick. It was a nice tight fit in the air box. The price is a bit steep, but being washable means I won’t be needing another one for a while.
Allen Berna, Cleveland, Ohio
Outstanding. Have one in all 3 of my vehicles.
