O.S. Engine OSMG2698 Turbo Cold Glow Plug Details

The O.S. Engine OSMG2698 is a turbo cold-type glow plug intended for serious nitro setups that use turbo heads. It covers engines from .18 to .28 cu in (2.9 - 4.6 cc) and is suited to fuels with 25%+ nitromethane. The colder heat rating helps maintain reliable ignition and control when running in higher temperature conditions or during extended race runs.

Fitment and Key Points

Compatibility: Designed for turbo head engines in the .18 to .28 cu in range, compatible with engines such as the OS Max .21 VZ-B V-Spec.
Heat Rating: Cold - chosen to reduce overheating issues and hold timing steady.
Design: Shaped for turbo-style cylinder heads to ensure a tight, efficient combustion seal.
Thread Size: M8x.75mm - common thread for many turbo head nitro engines.

What nitro percentage is safe to use with this plug?

The plug is specified for fuels with 25% or greater nitromethane; running higher nitro levels is acceptable within that guideline and proper engine tuning.

How does thread size affect installation?

The M8x.75mm thread ensures a standard screw-in fit. If your engine uses the same thread spec the plug will seat correctly, otherwise avoid forcing it to prevent damage.

Should I change carb settings after installing this plug?

After installing a different heat-rated plug, check mixture at idle and under load and make small carb needle adjustments to maintain proper running and prevent overheating.
