AUTOLITE 3924 Spark Plug 4-3924 Copper

The AUTOLITE 3924 Spark Plug, SKU 4-3924, features a full copper core electrode designed to provide consistent performance in varied operating conditions. Its copper-glass seal bonds the insulator, terminal post, and center electrode together to support the required voltage at the spark gap while creating a gas-tight, leak-proof seal.

A multi-rib insulator helps reduce the danger of flash-over, while the one-piece terminal post adds strength. The integrated resistor helps reduce radio frequency interference (RFI) and electrode erosion. A cold-formed steel shell with precision-rolled threads supports dependable installation and service.

This spark plug is listed for the 2013 Indian Chief Classic, 2013 Indian Chief Dark Horse, 2013 Indian Chief Vintage, and 2006–2012 Honda TRX680FA Rincon [IRS]. Verify all cross-reference listings before purchase to confirm application.
