BBK 62 or 65mm?...are they worth the extra money or do i have to do something else for them to put out some power?

the 65mm will be your best bet, as you have a 4V motor. it will add a few ponies and some throttle response to a stock car, and as mods come, mainly induction, more power will come. added to a s/c car, you might pick up 10-15 ponies, depending on your setup.

UUhhh... a 65mm? Why not go with the 70mm. Thats the best size for the 4.6. I would go with Accufab though. Just my opinion.

id go with 70mm also. good for a stock motor and even better for a modded motor

BCisme

he has a 4V motor guys. i have a 70 mm on my GT, but he has a twin blade TB. 65 should be all you need, but if you can find a 70, (wich i've never seen) then get it.

I was going to suggest the 70 as well but your right with that twin blade set-up 65 is perfect.
