Having issues with your Arctic Cat Prowler 650 H1? If it's misfiring, hard to start, running rough, or just won't rev right, the CDI box (or ignition coil/module) might be to blame. This black box is like the brain for your engine's spark and fuel injection timing. This replacement is designed to match the OEM part number 0824-038 and is compatible with the 2006, 2007, 2008, and 2009 Prowler 650 H1 models. It's a direct swap—just disconnect the old unit's wiring harness (usually a 16-pin connector) and plug this one in. Before you buy, it's super important to double-check the part number on your old, failed unit and compare it to this one. Fixing a bad CDI can restore smooth idling, proper throttle response, and reliable starting. A relatively simple fix for a common problem on these UTVs.
