        Comments about NGK Racing Spark Plug:

        I use these for autocrossing my N/A '97 Probe GT w/ a 4 degree advance. Excellent performance. I don't use for everyday driving, as a matter of fact I install before race day and remove and detune when I come home from the races. They predictably work

          Comments about NGK Racing Spark Plug:

          Best plug to use in your 300-600hp turbo/supercharged Honda, and its NGK like stock. Will not cause detonation and will not break off like the worst plugs made in the world - platinum. Everyone knows copper is the BEST conductor with the strongest spark they are just to lazy to change them out as often as they need to :)

              A:

              This part NGK Racing Spark Plug, Part No. 4554 manufactured by NGK is universal and not a direct fit for your vehicle 1989 Toyota Corolla. This is a one size fits most, slight modification may be required. The Spark Plug gap for your vehicle 1989 Toyota Corolla should be 0.031 in.
