Specs At A Glance

Good To Know

Q: What are signs the sparkplug cap should be replaced? A: A cracked shell, corrosion inside the boot, a loose fit, or unreliable spark point to a worn cap. Checking it during routine tune-ups helps catch these issues early.

Q: Will this resistor cap change how my Tundra 250 runs? A: The resistor only suppresses electrical interference and does not reduce noticeable power. It should match the resistance value your Ski-Doo Tundra 250 ignition system calls for.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
