Autolite 4162 Copper Core Resistor Spark Plug

The Autolite 4162 is a copper core spark plug engineered to deliver quick starts and reliable performance while providing superior thermal control and improved resistance to fouling. This projected tip design extends further into the combustion chamber to aid in self-cleaning, reducing fouling at low RPMs and preventing pre-ignition at high speeds.

Key Features:

• Traditional nickel alloy electrodes with full copper core for enhanced thermal conductivity
• High alumina multi-rib ceramic insulator provides superior thermal conductivity and insulation for increased strength
• Built-in 5k Ohm resistor reduces radio frequency interference (RFI) and electrode erosion
• Cold-formed steel shell with precision rolled threads and one-piece terminal post for added strength
• Nickel-plated shell provides corrosion resistance for extended durability
• Copper-glass seal creates a 100 percent leak-proof, gas-tight seal

Specifications:

• Thread: 12mm x 1.25mm pitch
• Reach: 19mm (3/4")
• Hex Size: 11/16" (17mm)
• Gap: 0.028" (0.7mm)
• Seat Type: Gasket
• Terminal: Removable nut
• Torque: 11-19 lb-ft (cast iron or aluminum)

This spark plug comes with a 2-year warranty and is designed for approximately 30,000 miles of service life. Suitable for automotive, motorcycle, powersports, and small engine applications.
