When your small engine equipment doesn’t have the right technology, it can cause delayed start-ups and decreased performance, making your job that much harder. That’s why it’s important to equip your small engines with a premium spark plug that can deliver optimal performance when it matters most. Autolite® Xtreme Start™ spark plugs are designed with an iridium-enhanced finewire center electrode that provides 26% quicker*, more consistent starts compared to standard copper plugs; making it the obvious go-to choice for your outdoor equipment.


Its iridium-enhanced center electrode allows for 26% faster starts*, better fuel efficiency, and optimal engine performance
Provides superior heat transfer providing more durability under high temps and pressure for greater life
Its high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength
*Testing performed by independent lab in comparison to OE Standard Spark Plug
