Spark plugs for your Husqvarna MXA
The recommended plug is a BR8EIX. Match that code - spark plugs are thread-, reach-, and heat-range-specific, so the part number matters more than the brand. Worth considering: the BR8EIX iridium upgrade - it fits the same port, fires cleaner, and lasts far longer between changes.

What is the spark plug gap on a Husqvarna MXA?
The Husqvarna MXA spark plug gap is 0.024". 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.
How often should I change the spark plugs on a motorcycle?
