PORSCHE MEZGER ENGINES
BBI Autosport — Mezger Engine Service
Coolant Pipe
Coolant Pipe
Welding Service.
The Mezger engine — found in the 996 Turbo, GT2, and GT3 — is one of the greatest performance engines Porsche ever built. But it carries a well-documented factory weakness: plastic coolant pipe fittings that become brittle with age and heat cycling, and fail without warning.
When they go, the result is catastrophic coolant loss — and a engine that cannot be saved. This is not a matter of if. It is a matter of when.
This is a preventative service. Factory plastic fittings on the Mezger coolant system are a known failure point. BBI's billet solution eliminates the risk entirely — before it becomes a catastrophic and irreversible failure.
BBI's solution is a set of precision billet machined coolant pipe fittings, permanently welded in place by our in-house fabrication team. No plastic. No clamps. No compromises. This is the only permanent fix for the Mezger coolant pipe failure point.
BBI works extensively with Porsche dealers and independent workshops worldwide. If your car is with a trusted shop anywhere in the world, we can work directly with them on the send-in process. Contact us and we will coordinate the rest.
