Ignition coil packs, PACK OF 6
This OE Match ignition coil set includes six coil-on-plug ignition coils, designed for Porsche flat-six engines used in models such as the Porsche 911 (996 / early 997), Boxster (986 / early 987) and Cayman variants. Each coil mounts directly onto a spark plug and delivers the high-voltage spark required to ignite the air-fuel mixture inside the engine cylinders.
Fits:
Porsche Boxster 986 2.5L 1997 - 1999
Porsche Boxster 986 2.7L 1999 - 1902
Porsche Boxster S 986 3.2L 1999 - 1902
Porsche 996 C2 3.4L 1997 - 08/2001
Porsche 996 C4 3.4L 1997 - 08/2001
Please note: if you require screws order code 90006708901
The ignition coils generate the high-voltage electrical pulse required to create a spark at the spark plug. This spark ignites the air-fuel mixture inside the combustion chamber, enabling the engine to produce power.
Replacing all six coils at the same time ensures uniform ignition performance and prevents issues caused by mismatched coil age or output.
Function
• High-Voltage Generation: Converts 12-volt electrical power into ignition spark voltage
• Cylinder Ignition: Delivers spark directly to each spark plug
• Engine Performance: Supports smooth combustion and consistent power delivery
• Balanced Operation: Six matched coils ensure even ignition across all cylinders
Ignition coils operate in a high-temperature environment close to the engine. Over time the plastic housings can crack or internal components may weaken, leading to misfires, rough running or reduced engine performance. Replacing all coils together ensures consistent spark energy across all cylinders and restores smooth engine operation.
When to Replace. Consider replacing the ignition coils if you notice:
• Engine misfires or rough idle
• Loss of power during acceleration
• Check engine light related to ignition faults
• Cracked ignition coil housing
• During spark plug replacement or major engine service

Why these coils should be replaced
Age / thermal breakdown: coils are exposed to heat cycles and can develop internal insulation breakdown or hairline cracks in the housing. Over time this causes weak or leaking high voltage and intermittent sparks.
Misfire symptoms: a failing coil will cause single-cylinder misfires (P030x codes), rough idle, reduced power, increased fuel consumption and catalytic converter heating/damage if left. These are the most common reasons owners replace coils.
Carbon tracking / cracking: visible cracks or carbon tracking on the coil boot can provide a leakage path for spark, reducing performance and causing intermittent faults.
Connector / wiring issues: corroded or loose coil connectors can mimic coil failures; inspect connectors when replacing coils.

Common issues reported in practice
One or more cylinders misfire when the engine is hot but behave quite normally when cold (typical of internal coil failure or heat-sensitive cracks). Cracked coil housings on Boxster/996 cars, owners often replace the entire set for reliability. After a spark plug change, misfires appear because weakened coils can fail once higher-voltage plugs are installed; this is a frequently reported pattern.How to diagnose (practical steps)
Read codes: P0300 / P0301–P0306 point to misfires; note which cylinder is affected.Swap test: swap the suspected coil with another cylinder’s coil — if the misfire follows the coil, the coil is bad. (Common, quick field test used by owners.)Measure resistance: check primary and secondary coil resistances at ~20°C and compare to the ranges above.Visual inspection: look for cracks, carbon tracking, oil ingress, or damaged boots/connectors.Oscilloscope / HV probe: for deeper diagnosis a scope or HV probe can show spark energy, but most DIY diagnostics use swap + resistance checks.Related reference numbers

Why these coils should be replaced
Age / thermal breakdown: coils are exposed to heat cycles and can develop internal insulation breakdown or hairline cracks in the housing. Over time this causes weak or leaking high voltage and intermittent sparks.
Misfire symptoms: a failing coil will cause single-cylinder misfires (P030x codes), rough idle, reduced power, increased fuel consumption and catalytic converter heating/damage if left. These are the most common reasons owners replace coils.
Carbon tracking / cracking: visible cracks or carbon tracking on the coil boot can provide a leakage path for spark, reducing performance and causing intermittent faults.
Connector / wiring issues: corroded or loose coil connectors can mimic coil failures; inspect connectors when replacing coils.

Common issues reported in practice
- One or more cylinders misfire when the engine is hot but behave quite normally when cold (typical of internal coil failure or heat-sensitive cracks).
- Cracked coil housings on Boxster/996 cars, owners often replace the entire set for reliability.
- After a spark plug change, misfires appear because weakened coils can fail once higher-voltage plugs are installed; this is a frequently reported pattern.
How to diagnose (practical steps)
- Read codes: P0300 / P0301–P0306 point to misfires; note which cylinder is affected.
- Swap test: swap the suspected coil with another cylinder’s coil — if the misfire follows the coil, the coil is bad. (Common, quick field test used by owners.)
- Measure resistance: check primary and secondary coil resistances at ~20°C and compare to the ranges above.
- Visual inspection: look for cracks, carbon tracking, oil ingress, or damaged boots/connectors.
- Oscilloscope / HV probe: for deeper diagnosis a scope or HV probe can show spark energy, but most DIY diagnostics use swap + resistance checks.

Information
Replacement spark plug tube with new o-rings.
This spark plug tube is engineered as a direct replacement for the original Porsche spark plug tube. It provides a sealed, precision-fit channel through the cylinder head for the spark plug, preventing coolant ingress while supporting proper plug alignment and ignition performance.
Sold individually, 6 required per engine.
Fits:
Porsche 986 Boxster / Boxster S 1997 - 2002
Porsche 996 C2 / C4 3.4L 1998 - 2001
Diagram ref no 27, 28 and 29.
The spark plug tube provides a protective and sealed passage for the spark plug through the cylinder head. It:
• Supports and protects the spark plug from contamination by engine coolant
• Prevents coolant intrusion into the spark plug well
• Maintains electrical insulation and correct plug orientation
• Helps preserve consistent ignition performance and combustion integrity
Spark plug tubes are subjected to age, heat, coolant chemicals, and vibration. Over time the tube can stiffen, crack, or lose sealing effectiveness, allowing coolant to seep into the plug well. This often leads to misfires, poor starting, coil damage, or electrical shorts, and is a common service item on aging Porsche M96 engines. Replacing compromised tubes with a high-quality OE Match spark plug tube restores the correct seal and prevents expensive ignition coil or wiring damage, especially during engine rebuilds, head gasket services, or preventative maintenance.
When to replace:
• During cylinder head removal or service
• Evidence of coolant in spark plug wells
• Misfires or ignition issues traced to moisture/coolant
• Cracked, brittle, or deteriorated tube material
• Preventive refresh on high-mile engines

About Spark Plugs
OEMatch Spark Plugs — Fit, Function, Confidence
OEMatch spark plugs for Porsche models provide the ignition needed for efficient combustion across a wide range of engines. Offered in iridium, platinum and copper-core designs, these compatible replacements are engineered to match original dimensions and tolerances and suit routine servicing, tuning and rebuild work.
Available Types- Iridium — fine electrode for extended service life and stable spark.
- Platinum — balanced durability and conductivity for everyday use.
- Copper-core — rapid heat transfer and cost-effective option for older engines.
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche's original spark plugs.
OE (Original Equipment) refers to parts matching original specifications for the spark plugs and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM spark plugs engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Spark plugs deliver the high-voltage spark that ignites the air-fuel mixture in each cylinder. Their performance depends on correct heat range, electrode condition and gap setting. Under normal use the electrodes erode and insulators can foul or crack, so periodic inspection and replacement are part of routine engine maintenance.
Benefits Include- Restored ignition efficiency for smooth idling and reliable throttle response.
- Improved fuel economy and reduced emissions when plugs are correct for the engine.
- Enhanced durability from material choices matched to the application.
- Electrode erosion from prolonged high-temperature operation.
- Carbon or oil fouling caused by incomplete combustion or leaks.
- Thermal shock or cracked insulators from rapid temperature changes.
- Incorrect heat range or wrong gap setting for the engine.
Timely replacement restores ignition precision and helps maintain power delivery, fuel efficiency and emission control on Porsche engines. Choosing plugs suited to the engine and driving use reduces misfires and supports consistent running across the rev range.
Advantages- Coverage for classic and modern Porsche engines across multiple materials and specifications.
- Material options to suit high-mileage, tuned or original-condition engines.
- Made to original-spec dimensions for consistent performance and straightforward installation.
