This CDI Module for Coleman AT125-EX and AT125-UT ATVs is designed to increase your acceleration and performance. A simple "plug and play" CDI such as this one provides increased acceleration, particularly on hills and steep inclines.

This CDI module is equipped with a "rev limiter", which limits the speed (RPMs) of the engine, and it has a 5-pin square connector as shown.

Note: This CDI module will only work on 4-stroke engines such as those used on a new Coleman AT125-EX ATV. 4-stroke engines and 2-stroke engines require different engine timing. Though they may appear visually similar, a CDI module from a 4-stroke engine cannot be interchanged with a CDI module from a 2-stroke engine.
