Product Description:

Spark Plug, Bosch W3DPO
Discontinued by Bosch; no longer available.

This part has been superseded multiple times.
It replaces these part numbers:
   W265P21
   999.170.022.91
   999.170.034.90

This is a platinum plug as called for by Porsche specifications, and has a heat range of "3". The MFI cars from 1969-74 can also use the Bosch Silver W3CS spark plug as an alternative to the Platinum plug. In the Turbo models, we recommend sticking with the Platinum plug due to the increased cylinder pressures.

Spark plugs should be gapped before installation at Porsche specs:
   1967-68 Porsche 911S without CDI .35 to .40 mm (.012" to .014")
   1969-74 911E, 911S, 911 2.7L Carrera with MFI and CDI  .55 mm (.022")
   1975-94 3.0L and 3.3L 930 (with CDI) .60 mm +/- .1 mm (.023" +/- .004")

These are a non resistor spark plug and conform to the original System Design for total resistance values.
