Great price!
I love that I can order these on Amazon for less than half of what I would pay at the mechanic. They fit perfect, and they're a pretty easy install.

Easy to install and works perfectly
Great price. It does what it's supposed to do. Keeps my air flow clean. Super easy to install, I can't believe mechanics charge to do this. Once you see how easy it is, you'll save yourself that expense. The material is top-quality charcoal, so it cleans all the nasty mold particles from getting into the vehicle. There is no smell, and that is a plus.
