The Chevy 5.3 liter engine is an efficient and reliable engine with an estimated lifespan of up to 200,000 miles. However, in order to keep it running at optimal performance, it’s important to maintain the spark plug gap correctly. If the gap is too wide, it can cause misfiring, a loss of power, engine noise, and poor fuel economy. If the gap is too narrow, it can lead to spark plug fouling and engine overheating. In 2023, the spark plug gap for the Chevy 5.3 liter engine is still the same.
The spark plug gap on the Chevy 5.3 liter engine should be set to 0.060 inches (1.52 mm). This is the same gap that was recommended by the manufacturer in 2007. It is important to check the gap on the spark plug before installation to make sure it is correct. If the gap is not correct, the spark plug should be replaced or adjusted to the correct gap.
In order to get the correct gap, you will need a spark plug gap tool. This is a small tool that looks like a caliper. It measures the gap between the center and ground electrode on the spark plug. It is important to measure the gap on both sides of the spark plug to make sure it is the same on each side. If the gap is not the same on both sides, the spark plug should be replaced.

How to Adjust the Gap on the Chevy 5.3 Spark Plug
If the gap on the spark plug is not the correct size, it can be adjusted. The gap on the spark plug can be widened or narrowed by using a spark plug gap tool. To widen the gap, the tool should be inserted into the gap and the lever should be moved away from the center electrode. To narrow the gap, the lever should be moved towards the center electrode. The gap should be adjusted until it is 0.060 inches (1.52 mm).
Tips for Installing the Chevy 5.3 Spark Plug
When installing the spark plug, it is important to make sure that it is properly tightened. The spark plug should be tightened to the manufacturer’s recommended torque specification, which is usually between 15 and 20 ft-lbs. It is also important to make sure that the spark plug does not have any oil or debris on the threads, as this can cause the spark plug to not seat properly and can lead to damage to the engine.
Conclusion
Setting the spark plug gap on the Chevy 5.3 liter engine is an important part of keeping it running at optimal performance. The spark plug gap should be set to 0.060 inches (1.52 mm) and should be checked before installation. If the gap is not correct, it can be adjusted with a spark plug gap tool. It is important to make sure that the spark plug is properly tightened to the manufacturer’s recommended torque specification and that there is no oil or debris on the threads.
