The Hybrid Racing PRB to ZDX throttle body adapter makes installing a larger OEM drive-by-wire throttle body onto a "PRB" style intake manifold a breeze. With an inner diameter of 74mm, it seamlessly works with PRB-style intake manifolds without any modifications needed. This is the perfect solution for those using the popular large plenum Skunk2 street intake manifolds, which are known for their power but challenge of fitting onto newer generation platforms with a drive-by-cable bolt pattern. Compatible with the 06-11 Civic Si or 12-15 Civic Si models, the kit comes complete with everything needed for a quick and easy installation in under 30 minutes. Transform your ride into a high-performing machine with this adapter.
