Stock VW/Audi 2.0T FSI diverter valves, which bolt directly to the turbocharger housing, live shortened lives under the conditions you are likely to place on them: after an ECU upgrade, under increased boost pressures or when subjected to high temperatures. Forge Motorsport solves those problems with the easily installed, affordable Forge diverter valve, offered here by USP Motorsports.

The Forge DV is designed to do what any turbo diverter valve is supposed to: It seals under boost to prevent pressure loss, and when you throttle down it opens to release pressure. But Forge diverter valves also noticeably improve airflow, response and boost capacity compared with the stock VW diverter valve.

Why replace a stock GTI diverter valve that can’t stand up to the stresses of tuner modifications with an identical valve that’s also going to fail? That’s pointless. It’s also expensive. And sooner or later, the reduced reliability is going to come back to bite you in the driver’s seat — when the stock VW valve won’t hold full pressure, meaning your engine delivers less power on demand, and when the stock valve just quits. With a Forge diverter valve 2.0T engines run better and longer.

This Forge 2.0T diverter valve is precisely engineered to play its role flawlessly. The Forge bypass valve is more dependable and more responsive than the stock unit. And the Forge valve kit comes with all the parts you need, plus instructions, for hassle-free installation.

You might be thinking: Won’t this MK5/MK6 diverter valve create control problems? Not at all. Forge diverter valves have a pressure/vacuum-operated piston engineered to retain control by the OEM ECU programming. Even if you chip your ride — and who doesn’t want that kind of performance? — the software upgrades retain this part of the OEM program so that the valve works problem-free. No fault codes. No check engine lights. No kidding. You’ll get not only more dependability and quicker response, but also a passing emissions test grade.
