Do You Gap Iridium Spark Plugs?

Yes, you should gap iridium spark plugs. Iridium is a very hard metal and the tips of iridium spark plugs can wear down over time. When this happens, the gap between the electrode and the ground strap will become wider and your engine will run less efficiently.

If you’ve been wondering whether or not to gap your iridium spark plugs, the answer is yes! Gapping your plugs ensures that they will fire correctly and produce the best possible spark.

Here’s a quick guide on how to do it:

1. First, find the correct size gap for your vehicle. You can usually find this information in your owner’s manual or online.

2. Next, use a spark plug gapper tool to adjust the gap of your plugs.

If you don’t have one of these tools, a feeler gauge will also work.

3. Once the plugs are properly gapped, reinstall them into your engine. Make sure each plug is tight so it doesn’t come loose while driving!

4. That’s it!

Do You Gap Acdelco Iridium Plugs?

If you’re a car owner, then you know that there are a lot of different parts that need to be maintained in order to keep your vehicle running properly.

#2 –
Inspect the threads on both the old plug and the new Acdelco Iridium Plug. If there are any damaged threads, use a tap to clean them out before proceeding.

#3 – Use a feeler gauge to measure the gap between the ground electrode and center electrode on the new plug.

The correct gap for most applications is .044 inches (1.1mm).

#4 – Adjust the gap on the new plug if necessary by gently bending either the ground electrode or center electrode until you achieve proper clearance. Avoid over-tightening these screws as this can damage or break them entirely!

Can You Check Gap on Iridium Spark Plugs?

Iridium spark plugs are designed to last much longer than copper or platinum spark plugs. However, it is still important to check the gap on iridium spark plugs to ensure they are firing correctly. To check the gap on iridium spark plugs, you will need a feeler gauge.

Insert the feeler gauge into the space between the electrode and the side of the plug. The electrode is the part of the plug that sticks out and makes contact with the engine’s ignition system. If there is too much space between the electrode and side of the plug, it will result in a misfire.

Check your owner’s manual or service guide to find out what size gap your specific vehicle needs.

How Do You Close the Gap on an Iridium Spark Plug?

If your spark plugs have too much of a gap, it could cause engine misfires. You can avoid this by closing the gap on your iridium spark plugs. The easiest way to do this is with a feeler gauge.

First, find the correct size feeler gauge for your spark plug gap. Most iridium spark plugs have a 0.6mm gap, but it’s always best to check your owner’s manual or the manufacturer’s website to be sure.

Once you have the right size feeler gauge, insert it into the spark plug gap and see how much space is between the electrode and the side of the gauge.

If there is more than 0.6mm of space, you will need to close the gap. To close the gap, use a pair of needle-nose pliers to gently bend the side electrode until it is touching the side of the feeler gauge. Be careful not to over-bend the electrode, as this could damage it and cause engine misfires.
