Information
Spark plugs, WR4CC.
Spark Plug Set (Pack of 6) is an OE Match ignition service kit designed to replicate the original Porsche factory spark plugs in fit, heat range, and ignition performance. Supplied as a complete set of six, it is intended for compatible Porsche six-cylinder engines that specify this plug type.
PACK OF 6
Fits:
Porsche 911 3.2L Carrera 1984 - 1989
Non Catalyst.
This OE Match spark plug set contains six identical spark plugs, each manufactured to OE-equivalent specifications to ensure consistent combustion and dependable ignition across all cylinders. Built to withstand high combustion temperatures and sustained electrical load, these plugs help maintain smooth engine operation, stable idle, and reliable power delivery.
Replacing spark plugs as a complete set is essential for balanced ignition and even engine performance. Over time, worn or mismatched plugs can cause misfires, hesitation, increased fuel consumption, and uneven combustion. This OE Match pack of six provides a cost-effective solution for routine servicing, tune-ups, or ignition maintenance while maintaining OE-level performance and fit.
All plugs are direct-fit replacements and install without modification.
Function:
• Provides reliable ignition for all six cylinders
• Supports smooth idle and responsive acceleration
• Helps maintain fuel efficiency and balanced combustion
• Supplied as a complete engine set for correct servicing
Spark plugs degrade over time due to heat and combustion stress. Replacing all six plugs together ensures consistent ignition timing across cylinders, prevents misfires, restores smooth performance, and helps protect catalytic converters from damage caused by incomplete combustion. Using an OE Match set ensures reliable performance without compromising fit or function.
When to replace:
• Engine misfires or rough idle
• Reduced throttle response or loss of power
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine tune-ups or ignition system servicing

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

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

This OE Match ignition coil is designed to match the original Porsche component in shape, electrical characteristics and mounting configuration. It integrates the spark plug connector and coil housing, delivering high-voltage ignition directly to the spark plug for reliable combustion.
This component is commonly replaced during ignition system maintenance, particularly when misfires occur or when performing full ignition service.
The ignition coil converts the vehicle’s low-voltage battery power into high-voltage electrical energy, creating the spark needed to ignite the air-fuel mixture in the engine cylinders.
A properly functioning coil ensures smooth engine operation, consistent power delivery and efficient combustion.
Ignition coils are exposed to high heat and vibration within the engine bay. Over time they can develop cracks in the housing or internal electrical faults, which may cause engine misfires, rough running or loss of power. Replacing worn ignition coils restores proper ignition performance and helps maintain smooth engine operation.
When to Replace. Consider replacing the ignition coil if you notice:
• Engine misfires or rough idle
• Loss of power during acceleration
• Check engine light related to ignition faults
• Cracked or damaged coil housing
• During spark plug or ignition system service
