IRIDIUM POWER Spark Plug IW22 for Porsche 911 T / 924 / 944 S2 - 9991700IW22
Code: 9991700IW22
Ultra Fine Electrode
By harnessing the power of Iridium, DENSO is suddenly able to shrink the surface area of the center electrode - the critical component of a spark plug. Unlike a typical platinum plug that has a 1.1mm diameter center electrode, DENSO Iridium Power plugs have the world's smallest center electrode measuring 0.4mm in diameter. This means that the voltage requirements are decreased while firing performance is greatly improved.
Fits:
Porsche 911 T 2.4L 09/1971-08/1973
Porsche 914 2.0L 6 Cyl. 1969-76 (kW 81; Engine 901.36 / 37)
Porsche 924 2.0L 01/1976-08/1985 (kW 92; Engine XK - XJ)
Porsche 944 3.0L S2 12/1988-07/1991 (kW 155; Engine M44.41)
