If you’re like most people, you probably don’t know what pre-gapping is or why it’s important. Pre-gapping is the process of setting the gap between the electrode and the spark plug tip to the correct size for your engine. This is important because if the gap is too small, the spark will be weaker and may not ignite the air/fuel mixture properly.
If the gap is too large, the spark will be too strong and can cause damage to the electrodes. Denso Iridium Spark Plugs are pre-gapped for most applications, which means you don’t have to worry about setting the gap yourself.
If you’re looking for a top-of-the-line spark plug, you may be wondering if Denso Iridium spark plugs are pre-gapped. The answer is yes! These premium spark plugs come with a factory-set gap that’s optimized for most vehicles, so you don’t have to worry about adjusting it yourself.
That said, it’s always a good idea to check your vehicle’s owner manual to see what the recommended gap size is before installing any new spark plugs.
Are Denso Iridium Spark Plugs Pre Gapped?
Do Denso Iridium Plugs Need to Be Gapped?
Iridium plugs are said to last up to 10x longer than copper plugs, so many people assume that they don’t need to be gapped. However, DENSO recommends that you do gap your iridium plugs when you first install them. The correct gap for most applications is .044″.
What is the Gap on Iridium Spark Plugs?
Iridium spark plugs are made with a small iridium electrode that is placed in the center of the plug. This design helps to improve the durability of the spark plugs and also provides a more efficient way to create a spark. The gap on an iridium spark plug is important because it helps to regulate how much voltage is needed to create a spark.
If the gap is too large, it can cause misfires and poor engine performance. It’s important to check your owner’s manual or ask your mechanic what the recommended gap setting is for your vehicle’s make and model.
How Do You Install Denso Iridium Spark Plugs?
If your vehicle is equipped with DENSO iridium spark plugs, you’ll need to know how to install them properly. Here are the step-by-step instructions:
1. Locate the correct spark plug for your vehicle.
Make sure you have the right tools on hand before starting the job.
2. Remove the old spark plug from the engine using a ratchet and socket. Be careful not to drop the old plug into the engine compartment.
3. Inspect the threads in the cylinder head for damage and clean out any debris that may be present. Apply a small amount of anti-seize compound to the threads of the new plug.
4. Screw in the new plug by hand until it’s snug, then tighten it another 1/8 to 1/4 turn with a ratchet and socket.
Avoid over-tightening, which can damage both the threads and the electrode tip onthe new plug.

How Do You Spot a Fake Denso Spark Plug?
When it comes to spark plugs, there are a few different brands out there. Denso is one of the more popular and trusted brands, so it’s no surprise that there are fake versions of their spark plugs floating around. Here are a few ways to spot a fake Denso spark plug:
1. Check the packaging. If the packaging looks cheap or counterfeit, chances are the spark plug inside is fake as well. Make sure to buy from a reputable source where you know the packaging will be genuine.
2. Examine the metal casing of the spark plug. On a genuine Denso plug, the metal casing should be smooth with no rough edges or imperfections. If there are any irregularities on the surface of the casing, it’s likely that the plug is fake.
3. Inspect the tip of the spark plug. The tip of a real Denso sparkplug should be made of durable materials like iridium or platinum and feature sharp firing points.

Denso Iridium Spark Plug Gap
If you’re looking for better performance and fuel economy from your vehicle, one upgrade you can make is to install Denso Iridium spark plugs. These plugs provide a number of benefits over traditional copper or platinum plugs, including improved ignitability, higher durability, and reduced wear. But before you install them, it’s important to know the correct spark plug gap for your application.
The standard spark plug gap for most vehicles is between .044 and .060 inches (1.1 – 1.5 mm). However, the specific gap requirement for your engine will be listed in the service manual or on a sticker under the hood. Once you know the correct gap for your engine, setting it is a simple matter of using a feeler gauge to measure the distance between the electrode and the side of the plug hole.
If the gap is too large or too small, simply adjust it by gently bending the electrode until you get the desired measurement.
Installing Denso Iridium spark plugs is an easy way to improve performance and fuel economy in your vehicle. Be sure to check your service manual or ask a professional mechanic to ensure you’re using the correct gap setting for your application.
