Description
Denso FK20HBR11 spark plug is a long-life iridium spark plug for high-performance engines in Toyota Crown (2001-2012), Mark X (2004-2019), and Lexus GS/IS/LS (2005-2019). Its 0.7mm iridium-tipped center electrode and platinum ground electrode deliver stable ignition, improving fuel economy by up to 3% and reducing emissions. Heat range 20 suits 2.5L-5.0L V6/V8 engines, lasting 100,000 km in Kenya’s hot, dusty conditions. TUV-certified, it features a 1.1mm gap for precise timing, with resistor design to minimize noise.
Key Features
- 0.7mm iridium center electrode for fine-wire spark and efficient combustion.
- Platinum-tipped ground electrode resists wear in high-rev applications.
- Laser-welded fine wire promotes longevity up to 100,000 km.
- 5kΩ resistor suppresses radio interference for clear electronics.
- Pre-gapped at 1.1mm for immediate fit in 2.5-5.0L engines.
- Nickel plating prevents corrosion in humid coastal areas.
