The CTS Turbo FMIC kit for the VW Golf IV 1.8T (Golf/GTI/Jetta) is suitable for standard and modified vehicles. Compared with the factory solution, it provides more efficient charge-air cooling, thanks to the high-density intercooler core and cast aluminium end tanks. All pipes are formed with a retaining bead at the ends, reducing the risk of the charge pipes coming off or leaking.
The kit uses black aluminium pipes, 4-ply silicone couplers and stainless steel T-bolt clamps. The intercooler features a pressure-tested core and is designed for use with more than 450 hp at the crankshaft. The core dimensions are 25.25″ × 8″ × 3″, while the total length between the end tanks is 35.5″.
Features
- High-density bar-and-plate core
- Mandrel-bent 2.5″-diameter pipes with black powder coating
- 4-ply silicone couplers and stainless steel T-bolt clamps
- Supports more than 450 hp
- Compatible with standard K03, K03s and K04 turbochargers, as well as the ATP Eliminator kit
- Also suitable for upgrades with a larger turbocharger; a CTS Turbo exhaust manifold is required, otherwise additional modifications may be necessary
On later MK4 models, when installing the MAP sensor, the factory green O-ring seal must be retained and the supplied O-seal fitted over it. The MAP sensor is not included in the kit.
Installation on Golf/GTI/Jetta vehicles may require trimming the bumper and cutting the support and bumper. After suitable modification, the original bumper grilles can be refitted.
Suitable for: VW Golf IV (1J), VW Jetta IV (1J).
