| The NGK 5553 is stock heat range for many Japanese import vehicles. When you increase power in your vehicle you need to use a colder plug to deter detonation and help pull heat out of the combustion chamber. NGK recommends one range colder for every 75HP-100HP increase. 7 is one range colder than 6. Use 7 range plugs if you have 75-100HP more than stock HP. Replacement/Direct OE plug for many vehicles including Honda and Mitsubishi. 14mm, 3/4" reach, 5/8" hex, gasket seat,projected tip |
