NGK 95525 iridium IX spark plug for the 1968-1969 Toyota Corolla 4-cylinder 1.1L, the 1969-1979 Corolla 4-cylinder 1.2L, the 1971-1979 Corolla 4-cylinder 1.6L and other vehicles ignites the air-fuel mixture in the cylinder with a fine wire iridium tip. This NGK Iridium IX spark plug is recommended for modified or high performance applications, or as an upgrade to OE nickel alloy spark plugs.
- Fine wire 0.6 millimeter iridium tip center electrode for high durability and a consistently stable spark
- Iridium alloy center electrode with 6x the density of platinum and an extremely high melting point
- Tapered cut ground electrode with a reduced quenching design for ignitability, acceleration and fuel efficiency
- Solid copper core of 98% pure copper for heat dissipation, conductivity and ultra wide heat ranges
- Trivalent metal plating for anti-corrosion and anti-seizing properties, with ease of installation and removal
