Works and fits my vehicle.
Size: 5424WS, Style: Workshop

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!
