A-Premium Iridium Platinum Spark Plugs Pack of 4 for 1.8/2.0L L4 Audi VW Porsche — Fine-Wire, OEM Fit

A-Premium Iridium Platinum spark plugs (pack of 4) are fine-wire replacement plugs engineered for reliable ignition and long service life in select L4 Volkswagen, Audi, and Porsche engines.

These spark plugs combine a fine iridium center electrode with a platinum ground for improved ignitability and extended durability compared with standard copper plugs. Designed to match OEM fitment and heat range requirements, this four-piece set replaces factory part numbers including PLFER7A8EG and 06K905601B/D and fits a wide selection of 1.8L and 2.0L L4 engines used across Audi, Volkswagen, and Porsche Macan models.

Which cars and engines will these spark plugs fit?

They were created to suit specific 1.8L and 2.0L four-cylinder engines across multiple model years. Compatibility covers many Audi A3, A4, A5, A6, Q5, Q7, S3 and TT/TTS variants, as well as Volkswagen Golf, GTI, Golf R, Beetle, Jetta and Passat applications, plus Porsche Macan 2.0L models.

• Replaces reference numbers: 94833, PLFER7A8EG, 95125, LFER7BHX, 06K905601B/D.
• Audi fitments include A3 (2015–2020), A4/A5/A6 (2016–2020), Q5/Q7 (2017–2020), S3 and TT/TTS ranges.
• Volkswagen fitments include Golf/Golf R/GTI, Beetle, Jetta, Passat across 2013–2021 model years.
• Porsche Macan 2.0L compatibility for 2017–2020.

How do these plugs improve ignition and engine responsiveness?

The iridium fine-wire center electrode requires less voltage to create a stable spark, improving combustion consistency at startup and light-load throttle. That translates to crisper throttle response and steadier idle compared with worn or generic copper plugs, while the platinum ground adds wear resistance for extended reliable performance.

• Fine iridium center reduces required ignition voltage.
• Stable spark across RPM ranges improves throttle feel.
• Platinum ground increases electrode life and gap stability.

What maintenance interval should I expect with these iridium platinum plugs?

Iridium-platinum construction is designed for long service life. For many drivers and driving conditions, replacement at roughly 80,000–100,000 miles maintains optimal performance; check your vehicle manual and driving conditions for specific guidance.

• Recommended replacement interval: about 80,000–100,000 miles under normal conditions.
• Inspect sooner if you notice misfires, rough idle, or poor fuel economy.
• Use correct torque and anti-seize practices during installation.

Are these A-Premium spark plugs an OEM-equivalent substitute?

These plugs are engineered to meet OEM specifications for thread size, reach, heat range and electrical performance for listed part numbers. They are manufactured to align with the fitment and ignition characteristics expected by the original equipment for compatible L4 engines.

• Designed to match OEM heat range and fitment profiles.
• Direct replacement for listed factory reference numbers.
• Manufactured to work with stock ignition systems and coil-on-plug setups.

Who is this for: The A-Premium Iridium Platinum spark plugs pack of 4 is suited for owners and technicians who need a durable, OEM-compatible replacement for four-cylinder Audi, Volkswagen, and Porsche 1.8L/2.0L engines. Choose this set if you want improved ignitability and extended service life over conventional plugs, need exact fitment for specified model years and part numbers, and prefer parts engineered to match factory specifications for everyday driving and routine maintenance.
