Hey Cuda I'v been running E-3 plugs in my mild street 340 for 3 years now and am very happy with them , little pricey but I feel well worth it. Hope it helps.
FOG,, pricey,, yes ! I would like to avoid that,ha. Trying to narrow this down sooo, it does not get to "pricey" as some of these plugs are higher n ah cats back. thanks, D.y
