1.8T to 2.0TFSI Coil Pack Adapter Plates – Audi & VW 1.8T 20V

Upgrade your 1.8T 20V ignition system to modern 2.0TFSI-style coil packs with these precision-machined coil pack adapter plates. Engineered from high-quality 6061 aluminum alloy, these adapters correct the height difference between factory 1.8T coils and 2.0TFSI coils, ensuring a secure fit and proper seal at the valve cover.

Ideal for street and performance builds, this kit allows you to take advantage of smoother idle, more consistent spark, and improved drivability while retaining a clean, OEM-plus engine bay look.
