NGK is a premium brand of spark plugs and have been used in daily drivers and race cars with great success.

This is a great all around 8 series non projected, non resistor spark plug. We run these in our 500AWHP DR750 E85 car that runs an AEM EMS Series 2. They pull clean, do not foul if your tune is not overly rich, and the non projected tip and 2 stage cooler than stock plug heat range helps prevent dangerous pre-ignition.

This plug has a good gap for 15 PSI on stock ignition out of the box, but you may gap as low as .022 depending on your boost level. We find that .025 - .028 is a great starting point once you get in the high teens to mid twenties boost.

Pack of 6 Spark Plugs

4554: Non Resistor
Center Electrode Core Material: Copper Core
Center Electrode Tip Material: Nickel w/ V-groove
Gap Size: 0.032
Ground Configuration: Standard
Ground Electrode Core Material: Nickel
