Throttle Body Angle Adapter - for GM LS and LT, and LT4 Intakes

The considerable angle of the LS, LT, and LT4 intakes can cause issues routing inlet plumbing and clearance to aftermarket accessory brackets. One option is to mount the throttle body upside-down, BUT this changes the air flow to the intake and can cause poor cylinder distribution and drivability issues. The 717-15 levels the throttle body for these swap applications without changing the flow the GM design intended. Other four-bolt intakes with routing issues can also benefit from this adapter. Low RPM correct Low RPM with throttle body upside-down LT car intake blade orientation shown above. Other LS and LT are reversed but the same effect applies.
