2022 Honda Pilot Spark Plug Type & Gap

Quick reference

Why the right plug matters

Choosing the correct spark plug for your 2022 Honda Pilot is crucial for optimal engine performance, fuel efficiency, and longevity. The spark plug is responsible for igniting the air-fuel mixture in your engine's cylinders. A plug that doesn't meet the manufacturer's specifications can lead to a host of problems, from misfires and reduced power to catalytic converter damage.

Key considerations when selecting spark plugs include:

• Heat Range: This refers to the plug's ability to dissipate heat. A plug that's too "cold" (dissipates heat too quickly) can lead to carbon fouling, while a plug that's too "hot" (dissipates heat too slowly) can cause pre-ignition and engine damage. Honda engineers meticulously select the correct heat range for the J35Y6 engine to ensure optimal combustion and prevent issues.
• Electrode Metal: Modern vehicles, like your Pilot, typically use long-life spark plugs with precious metal electrodes. The 2022 Honda Pilot, with its NGK DILKAR7G11GS plugs, uses iridium electrodes. Iridium is incredibly durable and resistant to erosion, allowing for a much finer electrode tip. This finer tip provides a more concentrated spark and a longer service life compared to traditional copper or even platinum plugs. While copper plugs offer excellent conductivity, their softer metal wears down quickly, requiring more frequent replacement. Platinum plugs are a step up from copper, offering better durability, but iridium is currently the standard for extended-life plugs.

How to gap a spark plug

While most iridium spark plugs come pre-gapped from the factory, it's always a good practice to double-check the gap before installation, especially with traditional copper or platinum plugs. For your 2022 Honda Pilot's NGK DILKAR7G11GS plugs, the recommended gap is 0.044 inches (1.1 mm). While these plugs are typically factory-gapped, slight variations can occur during shipping or handling.

To gap a spark plug, you'll need a specialized spark plug gap tool (either a coin-style or wire-style gauge):

1. Select the correct gauge: Use the appropriate feeler gauge or wire gauge for 0.044 inches (1.1 mm).
2. Check the gap: Gently slide the gauge between the center and ground electrodes. There should be a slight drag, indicating the correct gap. If the gauge slides through too easily, the gap is too wide. If it doesn't fit, the gap is too narrow.
3. Adjusting the gap (if necessary): For iridium plugs, extreme caution is advised when adjusting the gap due to the delicate central electrode. If adjustment is needed, only bend the ground electrode (the L-shaped metal piece) very carefully. Use the bending tool on your spark plug gauge or a pair of needle-nose pliers (with extreme care) to slightly widen or narrow the gap. Never pry or apply force to the center electrode, as this can damage the iridium tip and ruin the plug. If the gap is significantly off on an iridium plug, it
