Information
Iridium spark plug BPR8EIX - (Bosch ref W3DP / W3DP0)
This OE Match iridium spark plug features iridium-tipped electrodes, which provide a finer, more durable ignition surface compared to standard plugs. The enhanced electrode design allows for a consistently strong spark and improved wear resistance, helping maintain stable ignition and combustion over extended use.
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 924 2.0 Turbo 06.80 - 10.86 130kw 177hp Engine type M31.03
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
Manufactured to OE-equivalent standards, it delivers reliable performance under high heat and pressure conditions typical of Porsche engines. Its direct-fit design ensures proper thread engagement, correct heat range, and uncomplicated installation without modification. This plug is ideal for routine servicing, tune-ups, or replacing a worn plug while maintaining balanced engine operation.
The spark plug creates a precisely timed electrical spark inside the combustion chamber to ignite the air-fuel mixture. This controlled ignition supports smooth engine operation, efficient fuel burn, and consistent power delivery across the RPM range.
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
