What it is
This is an upgraded side-mount intercooler (SMIC) plumbing kit, sized 2.5" on the lower pipe and 2" on the upper pipe — larger than the factory plumbing diameter, intended to improve airflow to the intercooler.
What this kit does NOT fit — read before ordering
Turbo-specific requirements — this determines what else you need to buy
| Turbo | Additional Parts Needed | Notes |
|---|---|---|
| S7 or VNT17ALH | Silicone turbo hose (included, must be trimmed to fit) + 1.75" adapter (sold separately) | Turbo may need reclocking for proper hose fit |
| VNT17/22 or 1726 | None — no adapter needed | No 90° pipe runs to the intercooler on these turbos, so the adapter requirement doesn't apply |
| BEW engine (any turbo) | KermaTDI's upgraded SMIC (separate product) + 1.75" adapter | Turbo reclocking required; lower intercooler pipe may need modification. KermaTDI notes this is attempted at the installer's own risk. |
Common questions
Does this kit work with my stock VNT17/22 or 1726 turbo without buying anything else? Yes — those turbos don't need the adapter that S7/VNT17ALH setups require, since there's no 90° pipe to the intercooler on those turbo types.
Will this fit my 1999 Jetta or Golf? Only if your car's SMIC plumbing does NOT have the 3-bar adapter built into the upper plumbing. If it does, this kit isn't compatible as-is.
Does this work on a BEW-engine car? Only with KermaTDI's upgraded SMIC intercooler (a separate product), plus turbo reclocking, the 1.75" adapter, and possibly modifying the lower intercooler pipe. KermaTDI describes this combination as attempt-at-your-own-risk, not a guaranteed plug-and-play path.
Can I use this with a New Beetle? No, not currently compatible with this kit.
