Porsche 911S 2.2L 09.69 - 12.71 132kw 180hp Engine type 911.02
This OE Match iridium spark plug set includes six identical spark plugs, each manufactured to OE-equivalent standards for thread dimensions, electrode design, and thermal performance. The iridium-tipped electrode provides a finer and more consistent spark while offering superior resistance to wear compared to conventional spark plugs.
Turbocharged Porsche engines operate under high temperatures and increased combustion pressure, making ignition quality critical. This OE Match set helps maintain stable ignition, smooth idle, responsive throttle behaviour, and efficient combustion under boost. Replacing all six plugs together ensures balanced ignition across cylinders and reliable performance throughout the rev range.
Designed as direct replacements, these spark plugs install without modification and are ideal for routine servicing, tune-ups, or ignition system maintenance on classic 930 Turbo models.
Each spark plug produces a precisely timed electrical spark to ignite the air-fuel mixture in its cylinder. As a complete set, they ensure uniform combustion across all six cylinders, supporting smooth engine operation and consistent turbocharged performance.
Function:
• Produces a reliable and consistent ignition spark
• Iridium electrodes improve durability and spark stability
• Supports smooth idle, responsive throttle, and efficient combustion
• Direct replacement for compatible Porsche applications
Spark plugs naturally wear over time due to repeated heat cycles, combustion stress, and electrical load. Worn plugs can lead to misfires, rough idle, reduced power, and increased fuel consumption. Choosing an OE Match iridium spark plug helps maintain consistent ignition performance, prolonged component life, and dependable running characteristics that match the original factory intent.
When to replace:
• Engine misfires or rough idle
• Hesitation under acceleration
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine tune-ups or ignition system servicing

Spark plugs play a critical role in engine efficiency, smoothness, and power delivery. Over time, wear from heat and combustion stress can reduce spark quality, leading to misfires, hesitation, and increased fuel consumption. Replacing worn plugs with an OE Match unit restores proper ignition timing and helps maintain optimal engine performance.
Designed for direct installation with no modification required, this spark plug is suitable for routine servicing, diagnostics, or replacement of individual worn plugs.
Function:
• Generates a consistent ignition spark for combustion
• Supports smooth idle and responsive acceleration
• Helps maintain proper fuel efficiency and emissions control
• Direct-fit replacement for easy installation
A worn or incorrect spark plug can cause rough running, misfires, loss of power, and reduced fuel economy. Using a correct OE Match spark plug ensures ignition performance remains consistent with factory expectations, helping preserve engine reliability and long-term efficiency.
When to replace:
• Engine misfires or uneven idle
• Hesitation or reduced throttle response
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During tune-ups or ignition system maintenance

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.
