Fram AP5144 Platinum Spark Plug

The Fram AP5144 is an Autolite Platinum spark plug engineered with a platinum center electrode firing tip that provides improved performance and increased durability, making it a reliable choice for older engine applications and designs. The necked-down center electrode fires quicker and cleaner with less voltage for easier starts, quicker acceleration, and improved fuel economy.

Key Features:

• Full platinum firing tip assures virtually no gap erosion and fewer misfires for longer plug life
• Copper core improves resistance to fouling
• High alumina ceramic insulator provides thermal conductivity and superior insulation for increased strength
• High nickel alloy side electrode resists electrical and chemical wear to maintain a precise gap
• Multi-rib insulator prevents flash-over
• Nickel-plated shell is corrosion resistant for extended durability
• Includes built-in resistor for radio frequency interference suppression

Specifications:

• Thread Size: 14mm x 1.25mm
• Reach: 0.809 inches (20.55mm)
• Hex Size: 5/8 inch (16mm)
• Seat Style: Tapered
• Factory Preset Gap: 0.054 inch (1.37mm)
• Center Electrode: Copper core with platinum tip
