MSD's new 90mm LS Throttle Body answers the need for a high quality throttle body with a mechanical throttle mechanism that bolts to most factory and aftermarket intakes. MSD went through the time and expense to develop a cast throttle body assembly in order to achieve a unique parabolic bore form.
