The 4P Outlaw D16 CNC cylinder head brings a new level of quality and performance to Honda D16 engine enthusiasts and racers.  This is a highly developed port design that excels where others fall short.  The 4P D16 head not only carries huge CFM gains at high lift, it also carries big flow gains in low lift areas.  This is critical for many D16 owners that are running smaller lift camshafts.  Other heads that were tested showed 25-30 cfm gains at .500 lift, but they lost significant flow below .350.  The 4P head doubles their CFM gains up top and shows big gains in flow at ALL lift points bottom to top.

4P sets the cylinder head up for your application whether it is all motor or forced induction.  Our cylinder head program is all about pumping out the biggest horsepower, keeping it responsive, and doing so with increased longevity.

4P Cylinder Heads hold more world records than all others combined.
