I wrote to K&N Tech Dept to get the factory thoughts about moving up from the standard recommended HP-1008 to the taller HP-1010. Here's the response:
Thank you for your interest in K&N products. We only recommend using the oil filter that is listed for your application, the HP-1008, PS-1008 and/or SS-1008. Matching an oil filter by outside dimensions does not take into account the internal structures of the media, bypass valve (if it has one), inlet/exit holes and related.
Plus, if you use an oil filter that we do not list for the application, it can void the warranty on the oil filter. We design our oil filters to meet and surpass the factory filtration and flow requirements that way by using the correct oil filter will still give you the advantages you are looking for.
If you have any further questions, please reply to this email or call our Customer Support Team at 800-858-3333
