Spark plug connector Genuine Porsche part 99660210501

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

The Plasma Direct is an ignition coil with a built-in high-power amplifier. Plasma Direct Coils produce 4 times more spark energy than stock coils, and generate an ultra-fast multi-spark-discharge of 10 sparks up to highest RPM.

The spark amperage is increased by 100%, allowing the spark to reach many more molecules, which therefore accelerates the ignition and combustion processes. This is extremely important in forced induction applications, but also improves the performance of normally aspirated engines.
The Plasma Direct will increase horsepower and torque throughout the entire RPM range, as well as reducing fuel consumption. Even engines with legendary smoothness will be further refined with the Plasma Direct upgrade. Plasma Direct coils are OBD II compliant.

- 100% secondary current (Spark Amperage) increase.
- 4 times spark energy increase for the initial spark discharge.
- 8% Fuel Saving
- Easy installation.
- Compatible with all OEM components.
- Compatible with OBD-II (On-Board-Diagnostics).
