The Ignition Coil is a high-quality ignition system component designed to convert the vehicle's low-voltage battery power into the high-voltage electrical energy required to fire the spark plugs. Working in conjunction with the engine control unit (ECU), the ignition coil delivers precise spark energy to ensure efficient combustion, smooth engine operation, and optimum performance.

Manufactured to OEM specifications, this ignition coil provides reliable spark generation, consistent ignition timing, and long service life under demanding operating conditions. As a critical component of the ignition system, it plays a key role in maintaining engine efficiency, fuel economy, power delivery, and emissions control.
What This Product Does:
- Converts low battery voltage into high-voltage ignition energy
- Supplies electrical current to the spark plugs
- Ensures reliable ignition of the air-fuel mixture
- Supports smooth engine operation and performance
- Helps optimise fuel efficiency and combustion quality
- Contributes to reduced emissions and improved drivability
Symptoms Of Wear Or Failure:
- Engine misfires
- Rough idle or uneven engine running
- Loss of power and poor acceleration
- Poor fuel economy Hard starting or extended cranking
- Engine hesitation under load
- Check engine light illumination
- Ignition system or misfire-related fault codes stored in the ECU
Why Replacement Matters:
- Restores strong and consistent spark delivery
- Eliminates misfires and rough engine operation
- Improves fuel economy and combustion efficiency
- Enhances throttle response and power output
- Reduces harmful exhaust emissions
- Helps prevent catalytic converter damage caused by unburnt fuel
- Maintains reliable engine starting and smooth operation
- Ensures optimum ignition system performance and ECU communication

Information
Ignition coil 14v. Porsche 911 84-89 / 924S / 944 / 964 / 968 / 928 (Bosch ref: 0221118322)
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.
