Champion Spark Plug CCH400 - Copper Core Marine Spark Plug, Replaces Bombardier 507669

The Champion Spark Plug CCH400 is a copper-core marine spark plug built as a quality OE-type replacement for boat engines. Its copper core center electrode delivers increased conductivity and precise heat range control, giving the plug good overall wear characteristics even under the heavy, sustained loads typical of marine engine operation. The plug is engineered to resist overheating during hard running, and its construction includes corrosion-resistant materials to stand up to the damp, salt-exposed environment common to marine ignition systems.

Key strengths of this Champion spark plug include fouling resistance, superior corrosion resistance, and dependable, proven performance backed by manufacturing to ISO and SAE standards. The copper core electrode is the design feature that sets the heat range and conductivity performance, helping the plug maintain a stable spark and resist premature wear over its service life. It is sold and shipped as a single spark plug (unit count of one).

This plug is commonly used in Chrysler inboard marine engine applications and serves as a direct cross-reference replacement for Bombardier part number 507669. Always match the plug to your engine manufacturer's specification before installation.
