Glad I was able to clear that up for you
Yes we are a Prova Retailer, however any high quality filter will work. Just make sure its something at least as good as OEM if not better. K&N, PowerEnterprise, and Prova we have found to work very well and are what we used on personal cars and offer to customers. If we dont find it good enough to run on our own cars, we dont offer it to our customers
Typically for oil filters you want to stay away from the budget units as they dont have the same features such as a high quality units such as: bypass valve, internal construction to keep the filters shape, and the density of the filter to be correct for proper flow but yet allow for proper cleaning.
