I've heard good things about Wix. I dont have the part number off hand, but I am sure if you go to a parts store they should be able to get you the correct one.
theres two types of Purolator filter. the normal one, and one with a P in front of the part #. a P1 Purolator iirc both work fine. i use whatever one is in stock.
I'm running a Bosche filter in the Hoe
Bosch, Purolator 1, Wix, are all good for the money. With Mobile and K&N you start paying less for quality and more for the name IMHO.
I bought the Wix. They didn't have Purolator and there were Fram (sh*t), Mobil, and Bosch. Six seemed the best.
I always use NAPA filters which I think are made by wix?
