i have the PermaCool external filter kit. the filter is HUGE (Ford oil filter, i believe.) it doesn't seem like it would give any flow problems, and if i remember right, its good for 50,000 miles. i will probably replace at 40,000, just to be safe . it just seemed to be a better alternative to the factory kit - easier to remove and cheaper to replace the filter - any parts store should have them. it was $32 from Summit, or you could get the Summit brand for $28 (it looks to be the exact same stuff as the PermaCool, probably even manufactured by PC for Summit). includes a hole for a temp sender, and a plug if you don't want to install a gauge. hope that helps,
