This is a multi throttle body! It only looks like a normal tb! But it won't give you as much power as the dbilas!
Groupbuy for the GMC ?
- Zero Fighter
The original TB is able to be fitted to 54,3 mmm, without being damaged.
The diamiter of 60 mm is also possbible by using the TB of the Renault Megane 2.0 16V.
An adaption is needed, but its done easyily.
