Enlarged throttle body.

[Muzzy76]

Found a bloke not far from me selling CNC machined 64mm throttle bodies as opposed to the usual 60mm.

Whats the advantage (if any) of fitting one?

If it's anything like the Vectra's I'm used to I'd assume a slight increase in low end torque.

Negligible difference mate. It's really not worth it. Save your money

Fair enough. Cheers.

Not even negligible. Complete waste of time and money
