Fram cartridge filter CH9911 looks very high quality at reasonable price. Amazon has it for $8.97/ea with free shipping for order of $25 or more. Amazon also has K&N HP-7010 for $9.62/ea. Rockauto has Fram for $7.83/ea but you pay shipping. If you like to buy from Rockauto, then MANN HU7196X at $8.42 is a good buy. Buy a bunch to reduce shipping cost per filter. Also, get the 5% discount code for Rockauto.
If you can get either Napa Silver or Pro Select for less than those price, I would go ahead and buy it from Napa.
