Information
Spark plug, FR6 DPP332,
This Bosch double platinum spark plug is a high-quality ignition component manufactured to Porsche OE specification. This spark plug provides precise fitment, dependable ignition performance, and long-term reliability, making it ideal for routine servicing or maintaining OEM standards.
Sold individually, 6 spark plugs required per engine.
Fits:
Porsche 997 Turbo 3.6L 2007-09 (M97.70)
Porsche 997 GT2 2007-09 (M97.70)
Featuring double platinum electrodes, this spark plug is designed to deliver a strong, consistent spark with improved durability and resistance to wear. Platinum technology helps maintain optimal spark gap over a longer service life, supporting efficient combustion, smooth engine operation, and reliable cold starting. Compared to standard plugs, double platinum designs offer enhanced longevity and stable performance under demanding driving conditions.
Key Features & Benefits:
• Genuine Bosch manufacture
• Double platinum electrode design for extended service life
• Strong, consistent ignition performance
• OEM-quality replacement Supplied as single spark plug
Spark plugs are essential for reliable ignition and efficient combustion. Over time they wear and lose effectiveness, which can cause misfires, rough running, reduced performance, and higher fuel consumption. Replacing them at the correct interval helps maintain smooth engine operation and protects the ignition system from unnecessary strain.
When spark plugs should be replaced:
• At the manufacturer’s recommended service interval
• If the engine misfires or runs unevenly
• When cold starting becomes difficult
• If fuel economy or performance drops
• When plugs show signs of wear, fouling, or corrosion
• During major servicing or engine maintenance

Iridium spark plug BPR8EIX - (Bosch ref W3DP / W3DP0)
Original equipment iridium spark plug, engineered to Porsche factory standards for turbocharged classic engines. Featuring a high-grade iridium centre electrode, this plug offers enhanced durability, precise ignition performance, and long service life while maintaining full OE compatibility.
Sold individually, 6 Required for 911 engines / 4 Required for 924 engines.
Fits:
Porsche 930 3.0 Turbo 01.75 - 12.77 191kw 260hp Engine type 930.50, 930.52
Porsche 930 3.3 Turbo 06.86 - 08.89 221kw 300hp Engine type 930.66

Porsche 911S 2.2L 09.69 - 12.71 132kw 180hp Engine type 911.02
This iridium spark plug ignites the compressed air-fuel mixture inside the combustion chamber, enabling controlled combustion and efficient power delivery. The fine iridium electrode produces a strong, focused spark, helping turbocharged engines achieve smoother running, improved throttle response, and reliable ignition under higher cylinder pressures.
Functions & Technical Role:
• High-energy ignition spark for efficient combustion
• Iridium electrode technology for exceptional wear resistance
• Improved ignition stability under turbocharged operating conditions
• Enhanced cold starting performance
• Reduced misfires and uneven running
• Factory-matched heat range & gap for Porsche turbo engines
• Longer service intervals compared to conventional spark plugs
Spark plugs are critical to combustion efficiency, especially in turbocharged engines where cylinder pressures are higher. Over time, electrode wear and carbon build-up reduce spark quality, leading to misfires, poor boost response, and reduced performance. Replacing worn plugs restores reliable ignition, protects engine components, and helps maintain smooth, consistent power delivery.
When to replace spark plugs:
• At Porsche-recommended service intervals
• During routine servicing or ignition system checks
• If experiencing misfires, hesitation, or rough idle
• When cold starting becomes more difficult
• If boost response or performance drops
• During engine rebuilds or restorations
• After long-term vehicle storage before returning to use
