Denso FK20HBR8 Iridium Spark Plugs for Lexus and Tacoma

The Denso FK20HBR8 is an iridium spark plug commonly used in automotive engines. Spark plugs play a crucial role in the ignition system of internal combustion engines, providing the spark needed to ignite the air-fuel mixture in the engine’s cylinders.

Iridium spark plugs are known for their durability and longevity due to the high melting point and corrosion resistance of iridium. This allows them to maintain a consistent spark gap over a longer period of time compared to traditional copper or platinum spark plugs. The “FK20HBR8” part number indicates specific details about the spark plug:

• FK: This likely refers to the plug’s design or series within Denso’s spark plug lineup.
• 20: This number might indicate the heat range of the spark plug. The heat range is a measure of how well the spark plug dissipates heat from the tip. Different engines require spark plugs with specific heat ranges to prevent overheating or fouling.
• H: The “H” could refer to the thread reach of the spark plug, which is the length of the threads on the spark plug body that screw into the cylinder head.
• BR8: This could denote the spark plug’s electrode gap size. The electrode gap is the distance between the center and ground electrodes and affects the spark plug’s performance.

It’s worth noting that spark plug compatibility depends on the specific make, model, and year of your vehicle. Always refer to your vehicle’s owner’s manual or consult with a trusted mechanic to ensure that you’re using the correct spark plugs for your engine.
