A-Premium Ignition Coil Pack & Iridium Spark Plug Kit — Set of 5 for Audi & VW, OEM-fit

A-Premium Set of 5 Ignition Coil Pack and Iridium Spark Plugs is a complete ignition service kit engineered to replace worn coils and plugs on compatible Audi, Volkswagen, Seat and Lamborghini engines for reliable spark performance.

This kit combines five high-quality ignition coils and matched iridium-tipped spark plugs to restore consistent ignition, reduce misfires and keep engine performance smooth on compatible 4- and 5-cylinder engines. The components are engineered to OEM-style specifications including blade terminals, bolt-on mounting, and manufacturer-recommended resistance ranges, making installation straightforward for routine maintenance or repair.

Which vehicles will this A-Premium kit fit?

The set fits a broad list of European models and specific engine types—primarily 2.0L turbocharged and selected larger V10/V8 applications—across Audi, Volkswagen, Seat and Lamborghini. Check the exact model-year and engine code before purchasing to confirm compatibility.

• Audi: A3, A4, A5, A6, A8 (selected years and engines), Q3, Q5, RS/TT/TTS variants as listed.
• Volkswagen: Beetle, Golf/GTI, Jetta, Passat, Tiguan, CC, Eos—multiple years and engine sizes covered.
• Seat and Lamborghini: Selected Leon/Altea models and Gallardo 5.0/5.2L years noted.
• Reference numbers included (e.g., 06H905115, 07K905715) to help cross-check fitment.

How do these coils and iridium plugs improve engine behavior?

Replacing worn ignition coils and aged plugs brings ignition timing and spark energy back to specification, which helps stabilize idle, reduce hesitation and minimize misfires. The iridium electrode is designed for a strong, focused spark and extended service life compared with standard plugs.

• Iridium+nickel spark plugs: fine electrode for sustained spark and longevity.
• Coil electrical specs: 0.56–0.68Ω primary, 8.1–10.1kΩ secondary for consistent output.
• Proper gap: factory 0.4–0.5 inches to maintain combustion efficiency.
• Bolt-on valve cover mounting and blade terminals for direct replacement.

What are the technical specifics and installation tips?

The components meet practical installation and torque specs so a competent DIYer or technician can complete the swap without engine modifications. Use the listed torque and thread sizes to avoid damage and ensure a gas-tight, secure connection.

• Thread diameter: 14 mm; installation torque: 25–30 N·m for plugs.
• Coil mount: bolt-on to valve cover; coil terminal quantity: 4 with blade type terminals.
• Verify plug gap before installation—set between 0.4 and 0.5 inches if needed.
• Cross-reference part numbers (UF50, UF523, GN10322, etc.) to confirm fitment.

When should I replace the ignition coils and spark plugs in this kit?

Replace coils and plugs if you notice misfires, rough idle, reduced fuel economy or check-engine codes related to ignition. Scheduled replacement intervals vary by vehicle and driving conditions; inspect coils and plugs during routine tune-ups or when diagnostic codes indicate ignition faults.

• Signs: consistent misfires, rough starting, or illumination of ignition-related fault codes.
• Maintenance: inspect during major service intervals or every 60–100k miles depending on vehicle.
• Always use proper torque and anti-seize guidance when installing spark plugs.
• Replace coils in matched sets when multiple cylinders show issues to prevent repeat failures.

Who this is for: This A-Premium kit is intended for owners and independent mechanics of compatible Audi, Volkswagen, Seat and Lamborghini models who need a full ignition renewal using OEM-style coils and long-life iridium spark plugs. It’s suitable for routine maintenance or targeted repairs when ignition performance has degraded, and for those who prefer a matched coil-and-plug set to ensure consistent cylinder operation across affected engines.
