Information
Spark Plugs, ZR5, Double-iridium.
High-quality OE Match Spark Plug Set (Pack of 4) is designed as a direct replacement. Featuring a double-iridium electrode design, this set delivers precise ignition, exceptional durability, and extended service life for compatible Porsche engines.
PACK OF 4
Fits:
Porsche 718 (982) Boxster 2.0L 2017>>
Porsche 718C (982C) Cayman 2.0L 2017>>
This OE Match double-iridium spark plug set includes four identical spark plugs, each manufactured to OE-equivalent standards for thread dimensions, electrode geometry, and thermal characteristics. The use of iridium on both the centre and ground electrodes allows for a finer electrode tip, resulting in improved spark efficiency, stable combustion, and significantly reduced electrode wear.
Double-iridium spark plugs are ideally suited to modern Porsche engines, which require accurate ignition timing and consistent combustion under high temperatures and pressure. This OE Match set helps maintain smooth idle, crisp throttle response, efficient fuel burn, and reliable power delivery over extended mileage.
Supplied as a complete set of four, these spark plugs install directly with no modification required and are ideal for scheduled servicing, tune-ups, or ignition system maintenance.
Each spark plug generates a precisely timed electrical spark to ignite the air-fuel mixture in its combustion chamber. As a complete set, they ensure uniform combustion across all cylinders, supporting smooth engine operation and efficient performance.
Function:
• Provides reliable ignition across all four cylinders
• Double-iridium electrodes improve spark stability and durability
• Supports smooth idle and responsive acceleration
• Helps maintain fuel efficiency and engine balance
• Supplied as a complete set for correct engine servicing
Spark plugs degrade over time due to heat and combustion stress. Worn plugs can lead to misfires, rough running, reduced performance, and increased fuel consumption. A double-iridium OE Match spark plug set offers improved longevity and consistent ignition performance, helping protect ignition coils and catalytic converters while maintaining optimal engine operation.
When to replace:
• Engine misfires or uneven idle
• Reduced throttle response or power loss
• 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 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
