QuadBoss 2005 Polaris ATP 500 High-Performance CDI

QuadBoss is known for making parts that help you get more out of your powersports vehicle. This high-performance CDI box is designed to do just that for a range of Polaris ATVs and UTVs. It works by changing how your engine's ignition timing works, which can help you get more power and a higher rev limit.

This CDI box features duplication circuits for added reliability and uses monocurve technology. The main benefit you'll notice is an increased RPM redline, raised by 1,000 RPM over the stock unit. This, along with altered ignition advance curves, helps improve performance throughout the entire RPM range, giving you a bit more pep when you need it. It's a well-built part that's straightforward to install, often just plugging in where the original unit was.

This unit fits a variety of Polaris models, including the 2005 ATP 500, 2005-2009 Ranger 500 2x4, and 2004-2009 Scrambler 500 4x4. Please note that this part is not CARB approved and cannot be shipped to California.
