Mark, just curious I only run luber finer filters lff-6012 have you ever compared them the ac delco tp-3012 is rated at 98.6% effiencent @ 4 microns and the luber finer is rated at 99.4% effiencent @ 4 microns I've been running them since 2006 and I have to say the truck runs smoother and quieter the rating is better as well as the price difference at the dealership where I work the ac delco tp3012 is 50.00 and the luberfiner from a semi truck dealership up the road is 31.65 would you give me your opinion and views on this filter or try one for your self and tell me how you like it I also only run Baldwin filters on my Kennedy pump setup there again a local truckpro semi truck parts house filter is only 35.xx dollars rated at 3 microns thanks in advance mark take care and God bless
