TracTuff Water Bypass Adapter – 06-11 Civic Si/04-08 TSX/03-07Accord
The TracTuff Water Bypass Adapter is an essential upgrade for enthusiasts looking to install an aftermarket PRB or PRC-style intake manifold on their K20Z3-powered 2006-2011 Honda Civic or K24A2-powered 2004-2008 Acura TSX. The factory RBC-style cylinder head routes coolant through the intake manifold, but popular aftermarket manifolds do not. This adapter bridges that design difference, allowing the use of PRB/PRC-style manifolds without leaving the coolant bypass or EGR ports exposed.
Developed in 2008, the TracTuff Water Bypass Adapter was created to expand intake manifold options for K-series owners while improving performance and serviceability. It provides a direct coolant bypass connection and seals the unused EGR passage. Even if you keep the stock manifold, you’ll benefit from reduced intake manifold temperatures by removing hot coolant circulation. This also eliminates the need to drain or bleed the cooling system every time you remove the intake manifold, simplifying maintenance and swaps.
