If the gap is too big or small, the engine may not work well. Pre-gapped spark plugs save you time. You do not need to adjust them. This makes them easier to use. Autolite spark plugs are often pre-gapped. This means they are ready to install. Proper gapping improves performance. It also helps with fuel efficiency.
What Is Pre-gapping?
Pre-gapping means the spark plug gap is set before sale. The gap is the space where the spark jumps to ignite fuel. Correct gap ensures efficient engine performance. Autolite spark plugs often come pre-gapped. This saves time for users.
Proper gap size is crucial for engine power. It affects fuel burn and engine efficiency. Pre-gapped plugs help in better combustion. This leads to smoother engine runs. Users get better fuel economy. Engines also start easier.
Factory Gapping Process
Autolite spark plugs follow strict manufacturing standards to ensure high quality. Each spark plug is made to precise dimensions. This helps in providing good performance. The factory sets the gap during production. This process ensures consistency. It reduces the need for manual adjustments by users. A consistent gap helps in smooth engine performance.
Every spark plug goes through quality control checks. These checks ensure the gap is correct. Workers inspect each spark plug carefully. Machines also help in this process. They detect any issues. This dual inspection method ensures reliability. It also helps in maintaining the standard gap. Users can trust the quality and performance.

Checking Gap Before Installation
Checking the gap before installation is crucial for optimal performance. Autolite spark plugs are usually pre-gapped, but always verify the gap. Accurate gapping ensures proper ignition and engine efficiency.
Tools Needed
A gapping tool, a wire feeler gauge, and a clean cloth are needed. The gapping tool helps measure and adjust the gap. The wire feeler gauge checks the precise gap. A clean cloth wipes any dirt or oil from the spark plug.
Step-by-step Guide
- First, remove the spark plug from its packaging.
- Next, use the gapping tool to measure the gap.
- Compare the gap with the manufacturer’s specifications.
- If needed, adjust the gap using the tool.
- Re-check the gap with the wire feeler gauge.
- Ensure the gap matches the required measurement.
- Finally, wipe the spark plug with a clean cloth before installation.
Potential Issues With Incorrect Gapping
Incorrect gapping can lead to engine misfires. The spark might not be strong. It can cause the engine to run poorly. This can make driving unsafe. Always check the gap before installing spark plugs.
Improper gapping affects fuel efficiency. The engine may burn more fuel. This leads to higher fuel costs. It also increases pollution. Properly gapped spark plugs help save money and protect the environment.

Adjusting The Gap If Necessary
Use a gap gauge to measure the spark plug gap. The tool has different thicknesses. Place it between the center and ground electrodes. Check the measurement. Compare it to the vehicle’s manual. This ensures correct spark plug gap.
If the gap is too wide, gently tap the ground electrode. Use a flat surface for this. Recheck the gap with the gauge. For a gap too small, use the tool to bend the electrode out. Make small adjustments. Re-measure each time. Repeat until the gap matches the manual.
