Tony, nice find!
I really liked the Purolator filters in general, and the sheer size of the L30165 had to help (lower pressure loss/more flow/a bigger garbage can for the crap).
Having a long history of modding stuff, AND changing oil at reasonable intervals, I was very pleased with the L301645 UNTILL they trippled the price.
After doing my oil pump mods, and installing an under hood mechanical oil pressure gauge I am not worried about the L30165, BUT appreciate the info.
I just called Advance Auto and they say its (L20073) like $4.00!
COOL!
Thanks Tony!
