NGK IFR6G-11K Iridium Spark Plug – Stock No. 1314
This NGK IFR6G-11K is a high quality iridium spark plug for reliable ignition and long service life. It uses a fine iridium centre tip with a platinum pad on the ground electrode for strong spark performance and reduced wear.
Expect smoother starts, cleaner idle, and consistent combustion under load. It will not add power by itself, but it helps your engine deliver its best, especially on tuned or hard-driven cars.
