Good To Know

Q: Is this throttle body a genuine GM part? A: No, it is an aftermarket replacement for GM part number 19420707 and is not manufactured by GM. Verify your engine code and intake manifold bolt pattern before ordering.

Q: Will this require a tune after installation? A: A larger 90mm throttle body often benefits from ECU recalibration for optimal idle and throttle response. Consult a tuner familiar with LS engine platforms.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
