Original quality spark plugs 0241135520 for Jetta

Core Advantages

1. Ultra-thin iridium center electrode design
   
   
   The center electrode adopts micron-level ultra-thin iridium alloy material, featuring low ignition voltage demand and fast flame propagation speed. It realizes efficient complete combustion of mixed gas, improves engine power output and throttle response, and effectively reduces vehicle fuel consumption and exhaust carbon emissions. Even under frequent urban start-stop conditions, stable ignition performance is maintained without misfire.
2. Wear-resistant nickel alloy ground electrode
   
   
   The side ground electrode uses high-temperature resistant nickel alloy with anti-erosion coating. It resists ablation under long-term high-temperature combustion, keeps the standard spark gap unchanged for a long time, and avoids engine shaking, hesitation during acceleration caused by electrode loss. The service life is far longer than ordinary copper core spark plugs.
3. Multi-layer anti-corrosion metal shell & high insulation ceramic
   
   
   The plug shell is treated with multi-layer galvanized anti-rust technology, resisting corrosion from rainwater and engine oil vapor to prevent thread seizure after long-term use. The insulator adopts high-purity alumina ceramic with excellent high voltage insulation performance, avoiding electric leakage and ignition failure under high engine load. Special high-temperature sealing gasket eliminates cylinder head air leakage hidden danger.
4. Strict factory inspection & obvious improvement on common faults
   
   
   Each spark plug passes ignition voltage test, high-temperature ablation test and gap precision inspection before delivery. It thoroughly solves typical faults caused by aging spark plugs: engine misfire, unstable idle speed, weak acceleration, increased fuel consumption, exhaust black smoke and illuminated engine fault light.
