Core Exchange

Core Process

• Same routine as the earlier Touring electronic throttle-by-wire units, HPi utilizes the stock core electronics, and new units are turned around in about 5-7 business days.
• Send in stock throttle body. We make sure the electronics are properly working, then surgically remove them & give the stock body a proper burial. Stock units are tested when received to ensure stock electronics are working properly, then re-tested after assembly to assure everything was assembled correctly.

Core Requirements

• Pre-order requires sending in the stock core throttle body for electronics.
• HPI lists a 5-7 business day turnaround from the day the core arrives.
• Stock cores must be working and stripped of gaskets and mounting hardware, including fuel rail, MAP sensor, and injectors.
• HPI notes a $50 disassembly fee if the core arrives with extra hardware installed.
• Milwaukee 8 cores only require the stock throttle body portion; the manifold does not need to be sent in.

Core Shipping

• Ship cores to Horsepower Inc., Attn: Kyle, 57 Gasoline Alley, Suite A, Indianapolis, IN 46222.
• Include the purchaser name with the shipped core.
• Package the core securely so plastic side cover pieces and electronics are protected.
