The Honda K-series engine platform uses several different intake manifold and throttle body combinations across various model years and applications — and many serious K-series builders choose to mix and match components for optimal flow characteristics. The most popular swap is using a base K20A3 throttle body with a higher-flowing performance intake manifold like the RBC, RRB, RBB, RRC, or RSP. This adapter solves the bolt pattern mismatch with a precision-machined dual-bore solution (62mm AND 70mm) that allows clean integration of K20A3 throttle bodies onto premium K-series performance intake manifolds, eliminating the need to source matching throttle body and manifold combinations.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eDual-bore
