I recently replaced my old cabin air filter with this one, and the difference was noticeable right away. Installation was quick and straightforward took less than 10 minutes with no special tools needed. What I appreciate most is the air quality improvement. The airflow feels stronger, and there’s a clear reduction in dust, odors, and outside pollution entering the cabin. If you’re looking for an easy, affordable upgrade that actually makes a difference in everyday driving comfort, this cabin filter is definitely worth it.

Does not fit

Fitment is horrible, don’t waste your money. Tabs are already broken upon receiving. Does not hold on to hood.

Fit is ok

They are a definite improvement from my original 22 year old grills but they have some clear differences in quality of the chroming, if you compare oem to these side by side the oem grills look smoother. also they don't fit great at least not on my car, albeit with a bit of nudging they fit pretty close to the originals. Overall not bad for something that is a quarter of the price of the oem part
