QuadBoss 02-04 Polaris ATV Pro 500 4x4 PPS High-Performance CDI

QuadBoss is known for making reliable parts for ATVs and powersports vehicles. This high-performance CDI box is built to help your Polaris ATV run better. It’s designed to unleash more power and improve overall performance by changing how the engine gets its spark.

This CDI box has duplication circuits for better reliability, and it actually raises the stock rev limiter by 1,000 RPM. It also changes the ignition advance curves, which helps boost performance across the entire RPM range. This means you should feel a difference in how the engine pulls, especially at higher speeds.

This part fits a range of Polaris ATVs, including models like the Sportsman 500 HO, Ranger 4x4 500, and Scrambler 500 4x4. It's a solid option if you're looking to get a bit more out of your engine.
