Spark plugs for your Arctic Cat 250 Utility
The recommended plug is a DPR7EA-9. Match that code - spark plugs are thread-, reach-, and heat-range-specific, so the part number matters more than the brand. Worth considering: the DPR7EIX-9 iridium upgrade - it fits the same port, fires cleaner, and lasts far longer between changes.

Frequently asked
What spark plug does a Arctic Cat 250 Utility take?
GarageDex's powersports data shows the Arctic Cat 250 Utility uses a DPR7EA-9 spark plug, gapped to 0.035", or upgrade to the DPR7EIX-9 iridium plug.
What is the spark plug gap on a Arctic Cat 250 Utility?
The Arctic Cat 250 Utility spark plug gap is 0.035". Set the gap with a feeler gauge before install - iridium plugs come pre-gapped but always verify, since a wrong gap causes misfires and hard starts.
Are iridium spark plugs worth it on a Arctic Cat 250 Utility?
The DPR7EIX-9 is the iridium upgrade for the standard DPR7EA-9. It fits the same port and heat range, fires more reliably, and lasts far longer between changes - a worthwhile swap for most riders, though the standard plug is perfectly fine if you change plugs on schedule.
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.
