Frequently Asked Questions About the Best Spark Plugs For 2012 Chevy Equinox

What type of spark plug is recommended for the 2012 Chevy Equinox 2.4L engine?

For the 2.4L four-cylinder engine in the 2012 Equinox, iridium spark plugs are generally the recommended standard. The high-energy ignition system benefits greatly from the durability and long-life stability that iridium provides. While platinum plugs are acceptable, iridium (like the ACDelco OE or NGK Iridium IX) offers superior performance and change intervals.

How often should I replace the spark plugs in my 2012 Equinox?

The standard spark plug change interval for modern iridium plugs in the 2012 Chevy Equinox is typically around 100,000 miles. However, if you opt for platinum plugs, you should consider replacement sooner, generally between 60,000 and 80,000 miles, to maintain optimal engine efficiency. Always check your owner’s manual for the specific factory maintenance schedule.

Do I need to gap iridium spark plugs before installation?

Most modern iridium and platinum spark plugs come pre-gapped from the factory for common applications like the 2012 Equinox. While it’s always best practice to verify the correct gap (check your vehicle manual or the plug manufacturer’s specifications), it is highly recommended not to adjust iridium plugs unless absolutely necessary, as the delicate fine-wire tip can be easily damaged.

What are the common symptoms of bad spark plugs in a 2012 Equinox?

Bad spark plugs can cause several issues in your vehicle, including engine misfires (often felt as hesitation or jerking during acceleration), rough engine idle, decreased fuel economy, difficulty starting the car, or even the illumination of the Check Engine Light (CEL). Replacing old spark plugs is a core part of maintaining your 2.4L Equinox.

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

It is not always necessary, but for high-mileage 2012 Equinox models (over 80,000 miles), many mechanics recommend replacing both. Ignition coils degrade over time, and replacing both the coils and spark plugs ensures a complete refresh of the ignition system, maximizing engine performance and reducing the chance of misfires caused by a weak spark.

Will installing performance spark plugs improve my Equinox’s horsepower?

While installing premium plugs like the NGK Iridium IX will ensure you are getting the most efficient and consistent combustion possible, spark plug replacement alone will not significantly increase horsepower. Their primary benefit is restoring lost power, improving throttle response, and ensuring the 2012 Chevy Equinox maintenance is up to date, optimizing the power that the engine is already rated to produce.
