K&N HP-7013 Oil Filter Review

Average Reviews:

(More customer reviews)K&N are known for making fortified oil filters, but I didn't think there was much they could do to improve the pleated paper insert that goes into the permanent metal oil filter housing on my 4 cyl. Mazda 6.
Yet, the first improvement I noticed were the end caps that hold the pleats in place. The Mazda factory filter, and all aftermarket filters I have tried so far, have rubber discs that are glued to the edges of the pleats.
K&N have taken a plastic and dipped both ends of the pleats, embedding the paper into both end caps. The plastic is pliable and contains a bead for a good seal. All other filters use a disc of mesh around the center hole on both ends.
I don't have the means to perform micron analysis to determine how much or how little dirt gets through the filter. But I will be able to tell come next oil change whether this filter has fractured and collapsed along the paper folds, as I have noticed with other brands.
K&N include both O-rings, as do all other suppliers of this filter. I do not see any particular quality difference in these components.
Will update in about 2,000 miles.
