Product Description

Autolite AR3910X High Performance Racing Non-Resistor Spark Plug

Features & Benefits

• Yttrium-Enhanced Alloy enables up to 8% reduction in sidewire temperature for colder heat ranges designed to enable performance modifications and handle intense conditions.*
• Engineered with a cut-back ground electrode that delivers optimal ignitability of the flame kernel and better heat transfer, leading to quicker starts.
• Cut back ground electrode for better ignitability of the flame kernel
• The yttrium-enhanced alloy enables up to 8% reduction in ground wire temperature for colder heat ranges designed to enable performance modifications and handle intense conditions.
• Anti-corrosive nickel plating to prevent rusting better than black oxide
• Designed with an anti-corrosive nickel-plating prevents rusting better than black oxide, allowing the plug to maintain its durability and efficiency.
• Its high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength while preventing flash-over.
