Failed in less than 1 year
Starter began making noise, and finally on the last start, it would not disengage from starting (as in it sounded like you were still turning the key after the vehicle was already started), so it burned out the starter, had to replace with one from o'reilly's. I don't reccomend this one

Wow! If they make this for your car BUY IT!
Style: HCC2122-X
I was surprised to see a reusable cabin air filter listing for my car. I didn't know such a thing existed. And they're the same price as a name brand disposable. I hate sending things off to the landfill, so being able to wash and re-use this, even if it breaks down after a few washings, is still saving the landfill and my pocket book. Quality feels excellent. Fit is tight, but with a bit of persistence it squeezes in. Sure, I realize this won't have the same micron level as a disposable, but, I routinely open doors and windows, and these filters area about catching the big stuff for me - not the molecules I can't see and get blown in as I enter/exit anyway. Super quality piece, I wish there was a fitment available for all my cars. I'm definitely keeping my eye out!
