Install Notes:
We recommend a 3" coupler for the 70/74mm throttle bodies. The 3" coupler is just a bit loose on the 70mm, but a 2.75" is way too small. The 3" coupler is VERY tight on the 74mm, but it does fit. A 3.25" coupler on the 74mm is way too big. Shop for Couplers and Clamps

70mm S90-MIT-370
74mm S90-MIT-374

S90 throttle body Evo 8

Absolutely love the new throttle body fits with minimal modifacation to stock fuel line (slightly bend out of the way) much better throttle imput response and far firmer pedal feel as well as an increase in perfromance due to better air flow capabilities
