Autolite Racing Non-Resistor Spark Plug AR3911

The Autolite Racing Non-Resistor Spark Plug (part number AR3911) is a direct-fit replacement built to match the original equipment part.

Features:

• Engineered with a cut-back ground electrode that delivers optimal ignitability of the flame kernel and better heat transfer, leading to quicker starts.
• 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.
• Designed with an anti-corrosive nickel-plating prevents rusting better than black oxide, allowing the plug to maintain its durability and efficiency.
