Description
***Autolite went out of business, and this spark plug has been discontinued. We still have some AR50's and AR51's, but we are out of the AR3910X.
For 2027, LO206 rules will be updated to a new plug (probably the Brisk brand of plug, but it's not official yet).***
The Autolite Racing AR3910X spark plug is the spec plug for the Briggs & Stratton Racing LO206 engine.
- Designed specifically for racing applications
- New cooler running sidewire providing improved durability and less risk of pre-ignition
- Anti-corrosive nickel plating
- Required plug for LO206 in 2026 (will change to a different brand for 2027)
