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).

What This Product Does
The ignition coil transforms the vehicle electrical system's low voltage into a high-voltage pulse. This allows the spark plug to ignite the compressed air and fuel mixture at the correct point in the combustion cycle.
Functions
- Generates the high voltage needed by the spark plug
- Supports consistent ignition within its assigned cylinder
- Helps maintain smooth starting, idling and acceleration
- Forms part of the engine's direct-ignition system
Technical Details
- Genuine Porsche ignition coil
- Porsche part number: 9A160210408
- Supplied individually
- Six ignition coils are required per six-cylinder engine
- Supersedes Porsche references 9A160210401, 9A160210402 and 9A160210403
Symptoms of Fault
- Intermittent or persistent engine misfiresRough idle or hesitation during acceleration
- Difficult starting, particularly when the engine is hot
- Reduced engine power or limp modeI
- lluminated engine warning light
- Misfire or ignition-coil circuit fault codes
- Poor fuel economy caused by incomplete combustion.
Why Replacement Matters
Heat, vibration and electrical stress can gradually weaken the internal insulation of an ignition coil. Replacing a confirmed faulty unit helps restore dependable spark delivery and reduces the risk of continued misfiring. Check the spark plug, connector, wiring and engine earths during diagnosis, as faults in these areas can produce similar symptoms or place additional strain on the coil.

FAQs
Can an ignition coil fail only when hot?Yes. Heat can expose deterioration within the insulation or electrical connections, causing an intermittent misfire after the engine warms up.
Should a coil be replaced using only a fault code?
A fault code identifies the affected circuit or cylinder but should be supported by checks of the spark plug, connector, wiring, supply voltage and earth connection.
Should the spark plugs also be inspected?
Yes. Worn, damaged or incorrectly specified spark plugs can increase the electrical load placed on an ignition coil.

The spark plug provides a precisely timed electrical spark in the combustion chamber to ignite the air-fuel mixture. This ignition process is essential to converting fuel into usable power, ensuring smooth engine operation and consistent performance.
Function:
• Produces a controlled spark for efficient combustion
• Promotes stable idle and smooth acceleration
• Helps maintain fuel economy and emission standards
• Designed to exact Porsche OE specifications
• Durable and heat-resistant for long service life
Spark plugs wear over time from heat, combustion stress, and electrical load. Worn or degraded plugs can cause misfires, rough idle, reduced engine response, poor fuel economy, and increased emissions. Installing a genuine Porsche spark plug ensures the ignition system operates as intended by the factory, preserving performance, smooth running, and engine health.
When to replace:
• Engine misfires or rough idle occur
• Sluggish acceleration or inconsistent power delivery
• Elevated fuel consumption
• After reaching the manufacturer’s recommended maintenance interval
• During routine ignition system service or tune-up
