Information
Spark plugs, FR5 NPP, Double-iridium
High-quality OE Match double-iridium Spark Plug Set (Pack of 6). Direct-fit ignition solution for Porsche Macan (95B.1), Cayenne (958), and Panamera S (970.2), delivering long service life and OE-equivalent ignition performance.
PACK OF 6
Fits:
Porsche 95B.1 Macan S 3.0L / Turbo 3.6L 2014 - 2018
Porsche 958 Cayenne 3.6L V6 Turbo / V6 Turbo GTS 2015 - 2018
Porsche 970.2 Panamera S 3.0L 2014 - 2016
Double-iridium construction is particularly beneficial in modern Porsche engines, which operate under high combustion temperatures and demand precise ignition control. This OE Match set supports smooth idle, responsive throttle behaviour, efficient fuel combustion, and consistent power delivery over extended service intervals.
Replacing spark plugs as a complete set ensures balanced ignition across all cylinders, helping maintain smooth engine operation and long-term reliability. Designed as direct replacements, these spark plugs install without modification and are ideal for routine servicing, scheduled maintenance, or ignition system refresh work.
Each spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture within the combustion chamber. As a complete set, they ensure uniform combustion across all cylinders, supporting smooth running and efficient engine performance.
Function:
• Provides reliable ignition for efficient combustion
• Double-iridium electrodes improve spark stability and durability
• Supports smooth idle and responsive acceleration
• Helps maintain fuel efficiency and controlled emissions
Spark plugs naturally degrade due to heat, combustion pressure, and electrical load. Worn or outdated plugs can cause misfires, rough idle, reduced performance, and increased fuel consumption. Replacing all six plugs with an OE Match double-iridium set restores reliable ignition, balanced combustion, and helps protect ignition coils and exhaust components.
When to replace:
• Engine misfires or uneven idle
• Reduced throttle response or hesitation
• Increased fuel consumption
• At manufacturer-recommended service intervals
• During routine ignition system servicing

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 911E 2.0L 09.68 - 12.69 103kw 140hp Engine type 901.09, 901.11
Porsche 911S 2.0L 07.66 - 11.68 118kw 160hp Engine type 901.02 901.08
Porsche 911S 2.0L 09.68 - 12.69 125kw 170hp Engine type 901.10
Porsche 911E 2.2L 09.69 - 12.71 114kw 155hp Engine type 911.01, 911.04
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
