Spark plugs for your Kymco Mongoose 250
The recommended plug is a CR7E. Match that code - spark plugs are thread-, reach-, and heat-range-specific, so the part number matters more than the brand. Gap it to spec before it goes in and you're done.

Frequently asked
What spark plug does a Kymco Mongoose 250 take?
GarageDex's powersports data shows the Kymco Mongoose 250 uses a CR7E spark plug.
How often should I change the spark plugs on a atv?
Standard plugs typically want replacing every 8,000-12,000 miles (or per your service manual); iridium plugs go much longer. Fouled or worn plugs cause hard starts, misfires, and poor fuel economy - a cheap part that punches above its weight.
