anyone running one of these? Are they worth the money? Thanx.

Its a worth while mod, It made a difference on mine, more responsive. And I had it installed when I was stock.

IMHO only if you are adding stuff like headers,bigger exhaust, superchargers etc.. If not then then stock unit should handle your air intake with no problems.

Do not runn the 90mm if u do not heads/cam/blower/upgraded intake manifold.......waste of money...just send ur stock one in to get ported...cost like $200

If I were you the 85MM would be enough. The 90MM you will need to port the intake manifold to fit and then you will need a tune. The 85MM is direct bolt-on and go.

Im running a 90mm..... larger TBs are great, mods determine the size:smileup:
