NGK extended reach spark plugs, set of four

Fits: 1990-1997, 1999-2005, 2004-2005 MSM

NGK extended reach plugs in heat range 6. Recommended for use on turbo or supercharged cars. Fits all NA/NB Miatas.

The extended reach means the burn starts closer to the center of the combustion chamber, giving improved efficiency and power. Every Miata should run extended plugs.

Should you use anti-seize? Short answer, not on these. Here's the longer answer, straight from NGK: "NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize."

Sold in sets of four. That's enough for one car.
