Champion 7437 RE7PYP6 Double Platinum Power Spark Plug

The Champion 7437 (RE7PYP6) is a Double Platinum Power spark plug featuring platinum on both the center and ground electrodes for extended service life and superior wear resistance. The center electrode uses platinum fine wire that's riveted onto a nickel alloy base, while the ground electrode has a platinum pad welded to the surface.

Key Features:

• Fine-wire and V-trimmed center electrode creates a sharper spark focus than conventional spark plugs
• Exclusive Heat-Active alloy reaches operating temperatures quickly and maintains stable temperatures under varying engine loads
• V-trimmed ground electrode promotes sharper spark focus for improved ignitability
• Tapered seat design with 14mm thread diameter and 0.984 inch reach
• Built-in resistor for noise suppression
• Erosion-tolerant platinum electrodes minimize spark gap growth for maximum service life up to 100,000 miles

Widely designed for distributorless ignition systems, Champion Double Platinum Power spark plugs can maximize fuel efficiency and spark energy. Cross-references include OEM numbers: 12565996, 41-103, 41-105, RE10PYPB5, LTR5GP, PTR5A-13, and others.
