Toyota 9091901192 — Spark Plug
Overview
Spark plug Toyota 9091901192 ignites the air-fuel mixture inside the combustion chambers of petrol internal combustion engines. This part features an M14x1.25 thread, a 19 mm reach, and a 16 mm hex spanner size. The factory spark gap is set precisely to 1.1 mm. A nickel-alloy ground electrode with a U-groove combined with a copper core central electrode maintains consistent spark discharge under varied engine loads. The main body is manufactured from zinc-plated steel alloy for corrosion protection, while the insulator uses high-grade aluminium oxide ceramics. OEM cross-references include Denso K16R-U11 (part number 3120). The unit incorporates an integrated 5 kOhm resistor to suppress electromagnetic interference with onboard vehicle electronics.
Fitment covers Toyota Corolla, Camry, RAV4, Avensis, Carina E, Yaris, Celica, and Picnic models equipped with 1.3L, 1.6L, 1.8L, 2.0L, and 2.4L petrol engines (engine codes 4A-FE, 7A-FE, 3S-FE, 1ZZ-FE, 2AZ-FE) produced between 1992 and 2008. Replacement is necessary when experiencing engine misfires, rough idling, delayed cold starts, or increased fuel consumption. The scheduled service interval for standard nickel spark plugs is 20000 to 30000 km. Heavy soot accumulation, severe electrode erosion, or an expanded gap exceeding 1.3 mm indicate the need for immediate replacement to prevent ignition system stress and unburnt fuel entering the catalytic converter.
