Breaking Down the Features of NGK Spark Plugs 6899/3000.6641 6899 Spark Plug – CPR6EA9
Specifications
The NGK Spark Plugs 6899/3000.6641 6899 Spark Plug – CPR6EA9 boasts several key specifications that contribute to its performance and reliability:
- Part Number: 6899 / 3000.6641 (These numbers help ensure you are purchasing the correct plug for your engine).
- Thread Size: 10mm (This measurement ensures proper fitment in the cylinder head).
- Reach: 19mm (The reach determines how far the spark plug extends into the combustion chamber).
- Hex Size: 16mm (This is the size of the wrench needed to install or remove the plug).
- Gap: 0.9mm (This critical gap allows the spark to jump and ignite the fuel/air mixture).
- Resistor Type: Yes (A resistor suppresses radio frequency interference (RFI) which can affect electronic devices).
- Center Electrode Material: Nickel (Nickel offers good durability and heat resistance).
- Ground Electrode Material: Nickel (Similar to the center electrode, nickel provides durability and heat resistance).
- Terminal Type: Solid (This creates a secure and reliable connection with the spark plug wire).
These specifications are crucial because they directly impact the engine’s combustion process. A properly gapped and correctly sized plug ensures efficient ignition, leading to optimal performance, fuel economy, and reduced emissions. Using the wrong plug can cause misfires, engine damage, and poor fuel economy.
Performance & Functionality
The NGK Spark Plugs 6899/3000.6641 6899 Spark Plug – CPR6EA9 excels in its primary function: providing a consistent and reliable spark for efficient combustion.
