Quicksilver 892567Q NGK IZFR5J Laser Iridium Spark Plug, 1-Pack

Description

Description The IZFR5J spark plugs come pre-gapped as specified by your engine manufacturer. Use only the spark plug listed in your engine owner’s manual. Using the wrong plug can reduce optimum performance, reduce fuel economy or cause damage to your engine. Spark plugs are easy to change with common spark plug sockets. The NGK pure alumina silicate ceramic insulator provides superior strength, reduces breakage and better heat transfer. The ribbed suppressor seal extends resistance and prevents spark “flash over” and misfire.
