K-Tuned has added another model to their dual pattern cast throttle body line up. This 72mm version not only offers a larger bore but K-Tuned has omitted the EVAP and Map sensor provisions for a cleaner looking throttle body.

Like the 70mm version, it is designed to be a great budget and versatile option for someone looking for a throttle body that is larger than the stock 62mm unit. Thanks to its dual bolt flange pattern, it is direct fit for both the PRB/PRC and RBC/RRC manifolds and aftermarket manifolds with similar patterned t/b flange.  Compatible will all OEM sensors.
