CTS Coilpack Adapter Set For Bolt Down 1.8T Engines for FSI/TSI R8 Coilpacks

This complete set of billet aluminum adapters bolt down to the factory 20V 1.8T valve cover allowing you to run the longer coilpacks found on VW/Audi 2.0T FSI, TSI. Upgrading the coilpacks will allow you to run a larger spark plug gap while maintaining a strong spark output. Replacing your outdated coilpacks with the newer technology has shown increased reliability, smoother idle, increased off boost power, and in some cases improved fuel economy.

Benefits

• Allows you to upgrade to newer VW/Audi coilpacks (*adapter harness required for some early models)
• In-house CNC machined aluminum adapters
• Direct fit for all 1.8T 20V engines
