FAQ: Best Spark Plugs For 2012 Chevy Cruze

What kind of spark plugs does the 2012 Chevy Cruze 1.4L Turbo require?

The 2012 Cruze 1.4L Turbo engine originally came equipped with Iridium spark plugs due to the high heat generated by the turbocharger. Iridium or Iridium/Platinum combination plugs are highly recommended for optimal performance and long life, though some performance enthusiasts use copper plugs for maximum spark efficiency (with much shorter replacement intervals).

What is the correct gap size for the 2012 Cruze 1.4L spark plugs?

The correct gap size can vary slightly depending on the specific manufacturer and part number, but for the OEM-spec iridium plugs, the general specification is usually between 0.024 and 0.028 inches (0.6mm to 0.7mm). It is critical to check the gap on new plugs before installation, especially in sensitive turbocharged engines, to prevent misfires.

Should I replace my ignition coil pack along with my spark plugs?

For the 2012 Chevy Cruze 1.4L engine, it is often recommended to replace the ignition coil pack (UF669) simultaneously with the spark plugs, especially if the car has over 70,000 miles or if you are already experiencing engine misfires or rough idling. Replacing them as a kit is an effective way to guarantee the entire ignition system is optimized.

How often should I change Iridium spark plugs in my 2012 Chevy Cruze?

High-quality iridium plugs are designed for long service intervals. For the 2012 Cruze, most premium iridium plugs should last between 80,000 to 100,000 miles. Always check the specific manufacturer’s recommendation, as performance plugs may require replacement earlier.

Will installing new spark plugs help with poor gas mileage?

Yes. Worn out or fouled spark plugs can lead to incomplete combustion, causing the engine control unit to compensate by injecting more fuel. Replacing the old plugs with high-efficiency Iridium spark plugs will restore proper combustion timing, often resulting in noticeable improvements in both fuel economy and engine power.

Are copper spark plugs better for my turbocharged Cruze?

Copper spark plugs offer superior electrical conductivity compared to iridium, which translates to a marginally stronger spark. However, they cannot withstand the high heat and pressure of the 1.4L turbo engine for long periods. While they might be used in highly tuned setups, for a stock 2012 Cruze, iridium plugs are better for resisting heat damage and providing a long-lasting, reliable solution.
