Product Details

If you're looking to get more out of your Polaris ATV's engine, a high-performance CDI box can make a notable difference. This QuadBoss CDI box is built to unleash more power and improve overall performance by altering the ignition timing and raising the rev limiter. It's designed to work with a range of Polaris models, including the 1998-1999 Big Boss 500 6x6, 1995-1998 Magnum 425, and 1997-1999 Scrambler 500 4x4, among others.

This CDI box features duplication circuits for added reliability, ensuring consistent performance. Its monocurve technology and updated ignition advance curves work together to boost performance throughout the entire RPM range. A key benefit is the increased RPM redline, which is raised by 1,000 RPM over stock boxes, allowing your engine to rev higher and potentially access more power.
