Honda EG / EK / DC / EF K-Swap ProStreet EFR T3/V-Band IWG Turbo Manifold

Honda EG K-Swap ProStreet EFR T3 IWG Turbo Manifold

Full-Race’s K-series Single Scroll EFR Internal-WG turbo manifold evolved as an option for those looking to have fast spooling, reliable HP without the complexity and weight of external wastegates, BOV, and boost controllers. Ideal for road racing and street/strip setups, this proven design will spool faster, last longer, and produce more reliable power across the entire RPM range than any other manifold on the market. We recommend EFR7670 0.83 a/r for most setups.  EFR8374 0.83 if a built motor is used.
