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.

An easy swap
This fits just like the OEM filter and seems well made. This is my third one in this same brand/model. It does a good job filtering air to the intake evidenced by the crud in the pleats.
