The OE Match (Bosch style) ignition coil (Bosch MPN 0221118322, Porsche OEM 944.602.115.00 / 944.602.115.01) sold as the direct replacement coil, It’s the high-voltage transformer that converts 12–14 V battery energy into the high voltage a spark plug needs to ignite the air/fuel mix. Please note the Bosch product is no longer available so this is one of the only alternatives.
Fits:
Porsche 911 1984 - 1989 (not Turbo)
Porsche 924S 1986 - 1988
Porsche 944 1982 - 1991
Porsche 964 C2 / C4 1989 - 1994
Porsche 968 1992 - 1995
Porsche 928 Cars Up to 1988 *2 Ignition Coils Per Car
Replace the coil when any of the following apply:
• Out-of-spec resistance on primary or secondary (measured with DVM). If primary > ~1 Ω or secondary well outside the 5–9 kΩ region.
• Intermittent misfire(s), rough idle, loss of power, or poor fuel economy that follow coil diagnostics. Ignition coils degrade and can produce weak/inconsistent sparks before total failure.
• Check Engine Light with misfire codes (P0300–P030x) that point to a particular cylinder and a coil swap test proves the coil is at fault.
• Visible damage (cracked housing, carbon tracking/arcing, oil contamination of electrical terminals, corroded connectors). These are signs of imminent failure or arcing that can damage plugs/caps.
• Age / preventive maintenance: rubber seals, insulation and internal windings deteriorate with heat and time; on older cars it’s common to replace coils as part of ignition refresh.
Common failure modes / symptoms
• Cylinder misfires / rough running (single cylinder or random).
• Hard starts or no-start if coil output falls below what’s needed to light the plug.
• Check Engine Light with misfire codes (P0300, P0301… etc).
• Intermittent stalling or power loss under load (coil heating causes intermittent fault).
• Arcing / carbon tracking visible on coil body or cap — can cause cross-firing or misfires.
• Failed connectors / harness corrosion causing poor coil drive — sometimes harness/connectors are the root cause rather than the coil itself.
