Fluidampr Viscous Crank Pulley (ALL 1.8T)
[551201]

This may not seem like the first place to spend your money on but I'm thankful I did. Having the fluidampr on my car helped smooth out idle, chatter, and pull smoothly through the powerband. It will most definitely help with high revving motors that will be seeing track duty as well as your daily driver. Well worth the money!
