Why the right plug matters
The spark plug is a small but critical component in your Tacoma's ignition system. It creates the spark that ignites the air-fuel mixture, and its design has a significant impact on engine performance, fuel economy, and longevity. The original equipment (OEM) plugs for the 2020 Tacoma are long-life iridium units, chosen by Toyota engineers for their specific heat range and durability.
- Heat Range: This refers to a plug's ability to dissipate heat. A plug that is too "hot" can lead to pre-ignition and engine damage, while a plug that is too "cold" can foul and cause misfires. It's crucial to stick with the OEM-specified heat range.
- Electrode Material:
- Iridium: The OEM choice for the Tacoma, iridium plugs have a very fine center electrode that requires less voltage to fire. This creates a more consistent and powerful spark. They have the longest service life, often exceeding 100,000 miles.
- Platinum: A good alternative to iridium, platinum plugs offer a long service life and consistent performance, though not quite as long-lasting as iridium.
- Copper: While excellent conductors, traditional copper plugs have a much shorter lifespan (typically 20,000–30,000 miles) and are not recommended for modern coil-on-plug systems like the one in the Tacoma.
How to gap a spark plug
Even pre-gapped plugs should be checked before installation. A drop during shipping can easily close the gap. Use a feeler gauge or a wire-style gapping tool to verify the gap. If adjustment is needed, gently bend the ground strap (the curved piece of metal at the tip) to open or close the gap. Never pry against the delicate center electrode.
Replacement procedure tips
Both engines in the 2020 Tacoma use a modern coil-on-plug ignition system, where each spark plug has its own ignition coil sitting directly on top of it. This makes replacement relatively straightforward.
- Coil-on-Plug Removal: Use a 10mm socket to remove the bolt holding the ignition coil in place. Gently twist and pull the coil straight up to remove it from the spark plug.
- Anti-Seize Debate: This is a hotly contested topic. Modern spark plugs from manufacturers like NGK and Denso have a special trivalent plating that acts as an anti-seize coating. Adding more anti-seize can lead to over-torquing the plug, as it changes the friction coefficient. We recommend installing these plugs dry, per the manufacturer's instructions.
- Dielectric Grease: Apply a small amount of dielectric grease to the inside of the spark plug boot before reinstalling the ignition coil. This prevents the boot from sticking to the plug in the future and helps seal out moisture.
Known issues
The 2020 Toyota Tacoma and its 2TR-FE and 2GR-FKS engines do not have any widely known, common issues related to spark plug failure, such as the infamous breakage problems seen on some older Ford 3-valve engines. The design is robust and reliable when serviced with the correct parts and procedures.
