Extended Product Information

FAQs

What does 'single platinum' mean for a spark plug?

A single platinum spark plug features a platinum tip on the center electrode. This offers greater durability and a more stable performance compared to standard copper plugs over a longer lifespan.

What is the thread size and length of this spark plug?

This NGK Spark Plug 2761 has a M14 x 1,25 thread size and a thread length of 19.0 mm.

How do I know if this spark plug fits my car?

You must use the vehicle make and model compatibility tool provided. This spark plug is designed for specific Jaguar models and engine types.

What is the purpose of interference suppression?

The 10 kOhm interference suppression helps to reduce radio frequency interference (RFI) generated by the spark, which can affect vehicle electronics like radios or navigation systems.

Can I replace my old spark plugs with this one if the part number is different?

It is not recommended to substitute spark plugs unless you have verified compatibility through a reliable cross-reference or vehicle lookup tool. Always use the manufacturer-specified part number or a direct, confirmed replacement.

What is the spanner size needed for installation?

A 16 mm spanner or socket wrench is required to install or remove this spark plug.

What does the gasket seat do?

The gasket seat creates a seal between the spark plug and the cylinder head, preventing combustion gases from escaping and ensuring optimal engine performance and efficiency.

Troubleshooting

Engine misfire or rough idle

Ensure the spark plug is correctly installed and torqued. Verify that the spark plug wire is securely connected. Check if the plug is the correct part number for your vehicle. Consider replacing all spark plugs if they are old or worn.

Difficulty starting the engine

Confirm the spark plug is compatible with your vehicle. Check for proper fuel and air delivery. A faulty spark plug can contribute to starting issues.

Reduced fuel efficiency

Ensure the spark plug is the correct type and is installed properly. Worn or fouled spark plugs can lead to inefficient combustion. Consider replacing spark plugs at recommended intervals.

Setup, Compatibility & Care

Compatibility Verification:

Before purchasing, it is crucial to use the vehicle make and model tool to confirm that the NGK Spark Plug 2761 is compatible with your specific vehicle. This plug is designed for particular engine types and model years, as noted in the product details.

Installation:

  1. Ensure the engine is cool before beginning.
  2. Use a spark plug socket wrench with the correct size (16 mm) to remove the old spark plug.
  3. Thread the new NGK Spark Plug 2761 into the cylinder head by hand to avoid cross-threading. Ensure it seats properly.
  4. Tighten the spark plug to the manufacturer's specified torque using a torque wrench. Overtightening can damage the cylinder head or the spark plug.
  5. Connect the spark plug wire securely to the top of the new spark plug.

Care:

Spark plugs are wear items and are not typically cleaned or reused. Replacement is recommended at the intervals specified by your vehicle manufacturer or when performance issues are detected. Avoid using abrasive cleaners or solvents on the spark plug. Handle with care to prevent damage to the ceramic insulator or electrodes.
