Detailed Specifications

Published catalog specifications identify the plug with a heat range of 8, flat seat, 1.043" reach, resistor construction and platinum ground-electrode tip.

Performance Advantage

The 06K905601M is especially popular in the VW/Audi performance market because it provides an appropriate colder heat range for many modified Gen 3 turbo engines.

For compatible 1.8T and 2.0T Gen 3 TSI applications, this plug is commonly selected as one heat range colder than the OE plug, making it a popular choice for vehicles running ECU software, increased boost, and other bolt-on modifications.

A colder plug is not automatically better for every engine. Always follow your tuner's recommended plug and gap for your specific calibration.

Important Fitment Note

Do not assume this spark plug fits every VW or Audi 1.8T/2.0T engine.

This plug is intended for specific applications and is particularly associated with Gen 3 engines. It is not intended for Gen 1 or Gen 2 2.0T applications, according to current application data.

Always verify:

• Year

• Make

• Model

• Engine

• Engine code

• Factory spark plug specification

• ECU tune/software

• Recommended plug gap

For modified vehicles, use the spark plug and gap recommended by your ECU tuner.

Common Symptoms of Worn Spark Plugs

Worn or fouled spark plugs can negatively affect combustion and engine performance. Common symptoms include:

• Rough or unstable idle

• Engine misfires

• Check Engine Light

• Poor fuel economy

• Hard starting

• Hesitation during acceleration

• Reduced engine power

• Poor throttle response

• Engine vibration

• Misfires under boost or heavy load

Replacing worn plugs with the correct specification can help restore consistent ignition and smooth engine operation.

Note: Persistent misfires can also be caused by ignition coils, fuel delivery problems, vacuum or boost leaks, carbon buildup, or other engine issues.
