QUESTIONS & ANSWERS
Ask 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

I have an S & B mouthpiece will that work
So the stock lly mouthpiece or s&b mouthpiece will need a 3.5" to 4" silicone coupler, and a 30 degree 4" tube around 4"-5" long to fit the lbz style intake system, its not the cleanest look.... I would recommend the lbz hsp mouthpiece, it can be color matched and looks vary clean and flows extremely well on lly
