Show original supplier description
The Pierburg Boost Control Solenoid, offered by Forge Motorsport under the product code FMTVSOL, is an upgrade from standard 2-port devices found in many turbocharged vehicles. It is designed to work with 4mm vacuum lines, simplifying the installation process. This solenoid is specifically listed as fitting the Ford Focus RS MK1. While it is compatible with a variety of turbo-charged vehicles, it is important to note that this is an original Pierburg part, not manufactured by Forge Motorsport. Consequently, it is excluded from Forge's lifetime warranty. Forge Motorsport recommends that for proper installation and use, an engine builder or professional tuner should verify the fitting of this product to prevent potential engine damage. For any inquiries or assistance regarding the Pierburg Boost Control Solenoid, customers can contact the seller via phone at 512-982-9393 (Texas) or 562-981-6800 (California).
