O.S. Engine 12XZ(P) Speed Tuned Car Engine  [OSMG1990]

An IFMAR-approved 1/10 scale powerhouse!

On-roaders rejoice: the 12XZ is here to give your ride with title-taking performance. General fat is trimmed toward bare minimum, while unique changes deliver awesome power and dependability.

The crankcase and liner port are newly designed to increase torque at low- to mid-speed
A particular finish regarding crankshaft reduces friction and use, and crankshaft is silicone-filled for smoother air/fuel induction
Tungsten loads offer better balance at high rpms
Holes machined into the aluminum exterior head decrease fat and improve cooling
The 12F(B) carb is made to match the engine's energy traits; an RP6 radiance plug is roofed
