The Endura Performance Redtop R8 Ignition Coils are the upgrade for a powerful and stable ignition immediately tight red OEM+ appearance. These coils deliver approximately 10% more ignition energy, reduce misfires and are thanks to the plug & play design easy to assemble. Specifically developed for the Audi RS4 B5 / S4 B5 2.7T (V6 biturbo) and Audi S4 B8 / S5 8T 3.0 TFSI (V6).
Why better than original? Thanks to extra windings in the internal coils and high quality copper, these coils deliver a more powerful, more stable spark – even at high turbo pressure and temperature. The result is better combustion, faster throttle response and maximum reliability, from stock to Stage 3 tuning.
Advantages
• Fit guarantee: perfect fit, just like original
• +10% more ignition energy: cleaner combustion, fewer misfires
• Reliable under load: ideal for standard and tuned engines
• Plug & play: direct replacement of OEM coils
• Red design: sporty OEM+ look under the hood
• 12 months warranty
Important
• 2.7T (RS4/S4 B5): in versions with bolt-down coils and ICM (Ignition Control Module) are coil adapters and a ICM delete/conversion wiring harness required to push-down to use coils.
• 3.0T (S4 B8 / S5 8T): complete plug & play, no additional parts needed.
• Spark plugs & gap: Use OEM specifications or the values your tuner recommends.

Frequently Asked Questions
Will these coils work on a stock (non-tuned) engine?
Yes, they improve spark stability and reliability, even on standard engines.
Do I need adapters on my 2.7T (RS4/S4 B5)?
Yes, if you still bolt-down ICM coils are used. You will need adapters and an ICM delete/conversion harness. Do you already have push-down coils without ICM, then it is plug & play.
Do more powerful coils provide extra power?
Indirectly yes – the more powerful, steadier spark ensures more efficient combustion and improved performance, especially at higher turbo pressures.
Is a tune required?
No, a tune isn't required. However, be sure to use the correct spark plug and gap setting according to your tuner or OEM specifications.
