maybe there is less metal in the unit, maybe they make space for more filter material, which id prefer over a 'cooler' filter
hot is hot when youre taking it off anyway hahah
which reminds me, time for me to do an oil change. thanks for letting us know it takes 5L! i was going to ask that question
+1 on using an engine oil flush before a change. ive always used the nulon variety on all my cars, never had a problem.....
