Larger size TBW intakes for bigger inch engines
Indianapolis based Horsepower Inc (HPI) has expanded their throttle-by-wire product line by offering two larger sizes to accommodate the larger cubic inch motors.
Now available on exchange, 62-64mm and 68mm versions require the stock unit with working internal electronics and will be turned around in 3-5 working days - you will receive back a whole new throttle body, intake manifold, flanges and seals.
These larger size throttle bodies accept any stock bolt pattern air cleaner if the opening size is modified. All popular intake port configurations are available from 1.710 to 1.900 with B2 and Hurricane Head oval ports coming soon.
They are fully CNC ported in-house, utilize the stock fuel rail and map sensor, with the stock electronics tested before and after rebuild. They include billet intake flanges and seals, a Cometic throttle body gasket, double sealed bearings and maintain the stock bolt pattern and location. All components are made in the USA.
