TracTuff Water Bypass Adapter for Z3/K24 heads RAA, RBC, RBB, & RSP. Allows you to run manifolds made for K20A2/Z1 PRB/PRC or separate your coolant from your manifold, requires cutting off the coolant portion. Easy manifold swaps without leaking coolant.
Pulled from our RSX, no problems with this unit while other brands are prone to leaking. We ran a thin bead of Hondabond just around the o-ring for safe measure and would recommend the new owner do the same. Includes all original hardware and the separate 90° barb fitting which you will need.
