Sold Individually. You must select the correct quantity for your car.
This genuine spark plug is designed for engines using the 2.5 TFSI DAZA setup, as found in high-performance Audi models. It matches the original factory specification, so it fits and works in the way the engine was designed.
What this spark plug does
The spark plug sits in the top of the engine cylinder and lights the air and fuel mixture. This is what creates power. A worn or incorrect plug can cause misfires, poor starting, rough idle, or lost performance.
Using the correct genuine plug helps the engine run smoothly, maintain strong power, and keep fuel use under control. It also supports reliable cold starts and stable performance when the engine is hot and under load.

- Matches original Audi 2.5 TFSI DAZA specification for heat range and gap
- Designed to cope with high cylinder pressures on turbocharged engines
- Supports smooth idle, clean throttle response, and consistent power
- Reduces the risk of misfires under boost compared with cheap pattern parts
This plug is suitable for popular Audi 2.5 TFSI DAZA engines, often found in RS models. Always use the vehicle lookup on the site or check the Vehicle Fitment tab to confirm it is correct for your car.
Performance and maintenance notes
If your car is stock or lightly tuned, keeping to the recommended plug type and change interval is usually best. For heavily tuned cars or track use, plugs may need checking and changing more often.
Important: Always ensure spark plugs are installed by a competent person using the correct torque settings. Incorrect fitting can damage the cylinder head or cause running problems.
