QuadBoss Ignition CDI Box

If you're looking to get a little more out of your 2004-2013 Yamaha YFM350 Raptor's engine, this QuadBoss Ignition CDI Box is a solid option. It's designed to help unleash more power and improve the overall performance of your ATV's ignition system. By altering the ignition advance curves, it aims to boost performance across the entire RPM range, giving you a more responsive ride.

This CDI box features duplication circuits for added reliability, meaning it's well-built to handle the demands of your Raptor. A notable change is that it raises the stock rev limiter by a full 1,000 RPM, allowing your engine to spin higher and potentially access more power. It also uses monocurve technology, a straightforward approach to ignition timing that contributes to its performance enhancements.

Keep in mind that this part is not CARB approved and cannot be shipped to California. For other states, it's a straightforward replacement for your stock CDI unit, aiming to give your YFM350 Raptor a bit more pep.
