TracTuff's K20Z3/ K24A2 water bypass adapter allows RAA, RBC, RBB, and RSP cylinder head owners to run the more popular aftermarket intake manifold options that were designed for the earlier PRB/ PRC flange. The PRB/ PRC style manifolds do not have an integrated coolant passage so the coolant bypass hole is left open when used together. 

Even if you don't plan on running a PRB/ PRC style manifold... there are plenty of benefits that make this product a must have! The biggest benefit is in the reduction of intake manifold temps by eliminating the heat transfer/ heat soak associated with hot coolant running through the manifold. By modifying the manifolds flange (cutting off coolant portion) and running TracTuff's adapter, the coolant is kept away from the manifold completely, just like what you would find on the earlier PRB/ PRC heads, so NOW your Hondata IM gasket will really work!! We've seen drops as much as 18°!! Not to mention, the additional benefit of no longer having to drain the coolant when removing the intake manifold for maintenance or swaps... makes things a real SNAP!

NOTE: Starting 4/16/20 ALL water bypass adapter sales will include a 90° 1/2" NPT to 5/8" hose fitting as STANDARD. You no longer have the option of buying a plug for blocking the water bypass. Tractuff now offers an all new delete plate for deleting the water bypass and its function - click HERE.
