Quick facts

Part: NGK BPR8EIX spark plug
Fits: 2025-2026 Polaris 650 Indy Adventure 137 650cc and other vehicles

Hard starting, a rough idle or a misfire can mean the plugs are worn, though a weak ignition coil or a fuel delivery problem can be behind the same signs, so find the cause before you replace anything.

Fits

It is listed for a wide range of Polaris, Ski-Doo, Ferrari and Porsche models, and both the 2025-2026 Polaris 650 Indy SP 137 650cc and the 2025-2026 Polaris 650 Indy VR1 137 650cc are on that list. If your machine is not named here, look it up in the "Vehicles it fits" section. Each of these Polaris models takes two plugs, so plan on two; the count differs on other applications.
