Best Spark Plugs For 2017 Toyota Tacoma FAQ

Q1: What is the recommended spark plug replacement interval for the 2017 Toyota Tacoma?

A: The official factory recommendation for iridium-tipped plugs (which most modern engines use) in the 2017 Tacoma is generally 100,000 to 120,000 miles. If you use traditional copper plugs, this interval dramatically drops to around 30,000 miles. Always check your owner’s manual for the most precise spark plug replacement interval based on your engine type (2.7L or 3.5L V6).

Q2: Should I use Iridium, Platinum, or Copper spark plugs in my 2017 Tacoma?

A: For modern engines like those found in the 2017 Tacoma, Iridium is highly recommended. While copper offers great conductivity, iridium provides superior longevity and can withstand the higher operating temperatures and voltage demands, ensuring consistent Tacoma engine performance over tens of thousands of miles without requiring service.

Q3: What is the correct gap size for the spark plugs in the 3.5L V6 and 2.7L L4 engines?

A: The required gap size can vary slightly depending on the specific plug and engine, but generally, the 3.5L V6 runs a gap around 0.031 to 0.032 inches, and the 2.7L L4 is similar. It is critical to confirm the correct gap before installation, especially when replacing the plugs on the V6 3.5L spark plug gap specification, as many high-end plugs come pre-gapped but should always be double-checked.

Q4: Will changing my spark plugs improve my gas mileage?

A: If your current spark plugs are old, worn out, or fouled, installing a fresh set of quality plugs (especially iridium ones like NGK or DENSO) will likely improve your gas mileage and restore engine efficiency. Worn plugs cause misfires and incomplete combustion, which directly impacts fuel consumption.

Q5: Is it necessary to replace the ignition coils when replacing the spark plugs?

A: It’s not mandatory every time, but it’s highly recommended, especially if your Tacoma is approaching or exceeding 100,000 miles. Ignition coils can weaken with age, leading to intermittent misfires. Replacing the coils when replacing the plugs is considered smart preventative maintenance, often grouped together in an ignition system refresh.

Q6: Can I install these spark plugs myself, or should I take my Tacoma to a mechanic?

A: Replacing spark plugs on the 2017 Tacoma (particularly the V6) is a moderate DIY job. The rear bank on the 3.5L V6 can be tricky to access, requiring removal of some components. If you have basic mechanical knowledge and the right tools (a spark plug socket and torque wrench), you can do it. If you are unsure about reaching the back cylinders or setting the torque correctly, a certified mechanic is the safer option to protect your engine.
