If you are going to try a Mobil 1 filter, why not just get a K&N HP-2010 Performance Gold?
I don't know what the Mobil 1 costs, but you could call a local distributor for K&N and get them to order their filter. Or, pay Summit $8 extra per order and get some (I order a few at a time from Summit to spread that across a few filters, but I put way more miles on than you do).
