Description:
Autolite Platinum spark plugs provide a center wire platinum firing tip for improved performance and durability. These plugs fire quicker and cleaner with less voltage, creating easier starts, quicker acceleration and improved fuel economy versus standard plugs.
Features and Benefits:
- Full platinum firing tip assures virtually no gap erosion and fewer misfires for a longer plug life
- High nickel alloy side electrode resists electrical and chemical wear to maintain a precise gap for a longer lasting plug
- Leak proof, heat fused resistor for added stability
- Manufactured with a center wire platinum firing tip for improved performance and durability
- Necked-down center electrode fires quicker and cleaner with less voltage for easier starts, quicker acceleration, and improved fuel economy
- Super conductive yttrium enhanced ground electrode provides superior heat transfer
