Works
Decent quality, somewhat flimsy, not bad for the price. Fit perfectly, correct thickness.

As Good And Possibly Better Than OE
Here's an air filter that looks as if it came from the same supplier as the OE version. It fits without any problem and it should hold up easily. I change mine every 15,000 miles.
