The O.S. Engine P3 Turbo Ultra Hot Glow Plug, model OSMG2699, is produced to optimise turbo head racing engines from .18 to .28 cubic inches (2.9 to 4.6 cc). Its ultra-hot rating assists ignition at lower rev ranges and supports stronger throttle response on acceleration.
Intended to sit in the inner head of turbo-type cylinder heads, the P3 plug makes for easier starts and smoother idle, particularly when running on 20% nitro fuel. The result is dependable low-speed running and increased torque when you roll on the power.
