This is a set of billet adapters to retrofit FSI or TSI coilpacks to your 1.8T with bolt down coilpacks. The FSI/TSI
coilpacks allow you to run a larger spark plug gap, while maintaining a strong spark output. Testing has shown a
smoother idle with these coilpacks, increased off boost power, and in some cases improved fuel economy.
Replace your old bolt down coil packs with the newest VAG technology. You can use any FSI or TSI coilpacks
with these, which we sell separately.
These adapters let you eliminate the bolt down coil system and fully cover the spark plug holes to prevent water
and debris from reaching the saprk plugs and working end of the ignition coils.
Sold as a set of four - Designed for early 1.8T engines with bolt down coils (AEB, ATW, AMU, Etc.)
