This FMIC Kit for the VW MKIV 1.8T (Golf/GTI/Jetta) is an excellent upgrade for any stock or modified cars. This kit provides significant cooling improvement compared to the competition, and substantial cooling benefits over the factory setup. Improvements can be attributed to the high density intercooler core, and cast aluminium end tanks. Each pipe in this kit has been "bead rolled" so you don't have to worry about your boost tubes blowing off or leaking. If that wasn't enough for you, this kit also uses aluminum piping, 4ply silicon couplers and stainless steel T-Bolt clamps. See the picture above for the proper installation of MAP sensor o-ring (for late MK4 models). Make sure to keep the factory o-ring (green) and install the supplied sealing o-ring over it. Sensor not included in the kit. Note: If you're interested in maintaining the sleeper look, rest assured the stock bumper grilles can be installed on Golf/GTI/Jettta with minimal trimming.
