Works and fits my vehicle.
Size: 5424WS, Style: Workshop
The price is reasonable and was delivered on time. It’s a filter so there’s not much you can grade this on unless you do scientific analysis. Be certain to buy the filter that fits your car.

Good filter

It seems to be working. It’s not something that will make a tangible difference, but it fit my car and was easy to install.

Top quality at great price
Size: 5424WS, Style: Workshop
These are great filters for the money. The car dealer wanted 80 dollars to replace it. This can be done by anyone and buying it on here is even more savings. Do not fall for it at the dealer. Save your hard earned money!

Excellent Engine Air Filter — Keeps Your Engine Breathing Clean!
Size: 5424WS, Style: Workshop
It’s a high‑quality replacement that does exactly what you want from an engine air filter — it helps protect your engine and keeps performance strong.
Right away you can tell this is a well‑made part. The filter media has lots of pleats and high‑velocity cellulose material that’s designed to trap dirt and contaminants before they get into your engine, which helps reduce wear and tear on vital components. It offers up to ~98% filtration efficiency, so you know the incoming air is much cleaner and better for performance and fuel efficiency.
