MS throttle body inlet upgrade kit

The factory throttle body inlet pipe is made of flexible rubber. Under increased boost levels, it will inflate and can even blow right off. When that happens, you either get a dramatic loss of performance and unfiltered air into the engine, or the car just stalls – depending on your engine management. Either way, it’s bad.

Note that this pipe has a 1 3/8″ fitting for an upgraded bypass valve, as opposed to the stock 3/4″ fitting. We recommend pairing it with our Turbosmart unit, be sure to choose that option if don’t already have a plan.

As used in our Little Enchilada kit.

The instructions below are for our complete Little Enchilada kit, but the first section is applicable to this part.
