Autolite AR3910X Spark Plug Case (48 Pack) for LO206, Animal & Clone Kart Engines

If you’re maintaining multiple LO206 engines, running a race team, or stocking a kart shop, the Autolite AR3910X 48-count case is the smart way to stay ahead of race weekends. This is the same plug trusted in Briggs LO206, Animal, and clone kart engines, just packaged for volume use.

Bulk cases are popular with teams because plug changes become routine instead of a last-minute scramble. Fresh plugs for practice, fresh plugs for race day, and spares on hand when tuning or weather changes throw a curveball.

• 48 spark plugs per case for teams, shops, and high-usage programs
• Compatible with Briggs LO206, Animal, and most clone engines
• Consistent ignition across multiple engines and sessions
• Ideal for race teams, arrive-and-drive programs, and builders

Even when buying in bulk, reading the plug correctly is what actually protects your engine and lap times. Plug color, strap heat, and timing marks tell you more than most gauges if you know what to look for.
