Unlock the full potential of your EcoBoost engine with NGK one-step colder spark plugs. Specifically engineered for high-performance and tuned applications, these iridium spark plugs provide improved ignition efficiency, enhanced combustion, and increased durability under higher boost levels. When tuning your EcoBoost engine, increasing power output and adjusting air-fuel ratios often generates more heat. This can cause pre-ignition and engine knock, which can significantly reduce performance and reliability.

The NGK spark plugs are a crucial upgrade when tuning your engine, as their colder heat range helps to manage the increased thermal load by ensuring consistent spark performance in high-boost environments. By reducing the chances of knock, these plugs allow for more headroom when tuning, supporting higher horsepower without compromising engine safety.

Ideal for enthusiasts pushing their EcoBoost engines to the next level, NGK one-step colder spark plugs are essential for maximizing your custom tunes and ensuring smoother, more reliable operation. Whether youre looking to enhance throttle response, improve power delivery, or safeguard your engine, these spark plugs are the perfect choice to support your performance goals.
