QUESTIONS & ANSWERSAsk a Question
I saw that there are 4 options for filters. Which one is the best for flow? Which is the best for filtration? Which one do you recommend to people? Thanks.
Well the amsoil is the best seller, but green filter is really good also for flow and filtration. If it were my truck, I would use any of the 3 filters: Amsoil, aFe Pro Dry S, Green Filter
