The NGK CR8EIX features a fine-wire iridium center electrode and tapered cut ground electrode designed to support efficient ignition and consistent spark performance. Its high-melting-point iridium alloy provides excellent durability for demanding engine applications. Trivalent metal plating helps resist corrosion and seizing, while the copper core improves heat removal. The ceramic insulator and triple-seal construction provide additional strength, heat transfer, and leakage protection.
