The Skunk2 Throttle Body Adapter (RBC to Ultra Race) provides a seamless solution for installing RBC-pattern Drive-By-Wire K-Series throttle bodies onto Skunk2 Ultra Race Intake Manifolds. Designed with precision and performance in mind, this adapter features a 74mm throttle opening with integrated MAP sensor provision, which transitions smoothly into the Ultra Race manifold’s massive 90mm inlet—ensuring optimized airflow and unmatched efficiency.
Constructed from CNC-machined 6061 billet aluminum and anodized for corrosion resistance, this adapter plate guarantees a precise fit, leak-free seal, and long-lasting durability under high-performance conditions. It’s a must-have for tuners and builders looking to pair modern RBC-style throttle bodies with the high-flow capability of Skunk2’s Ultra Race intake systems.
