I couldn't say which is best but the first mod I made to my 05 V6 was a JLT CAI with an SCT performance tune and wow what a difference. If you are going to install a CAI please install a tune as well!
does anyone know where i can find a plenum cover and valve covers for a 2005 v6. New to the v6 end and having difficulty finding dress up parts:flag::flag::flag:
