When pushing Mazda 2.0L and 2.5L engines beyond factory limits, spark plug selection becomes critical. The NGK spark plug has consistently proven to be one of our preferred options at Fab9 Tuning for high-performance street, track, and forced-induction builds.
These plugs deliver reliable ignition stability under increased cylinder pressures, making them an excellent choice for turbocharged, supercharged, and aggressively tuned naturally aspirated engines.
Whether you’re running a Skyactiv-G, MZR, or built hybrid setup, the NGK Iridium IX provides the durability, heat management, and ignition consistency we look for in performance applications.
