Turbosmart FCD-1 Pneumatic Fuel Cut Defender Universal Turbo EFI Fitment
The Turbosmart FCD-1 Pneumatic connects between the boost source and fuel pressure regulator to divert pressure at set boost levels preventing ECU fuel cut in turbocharged EFI vehicles. It fits universally on models including Subaru Impreza WRX STI Mitsubishi Lancer Evolution and Nissan Skyline with boost-activated fuel cut systems. This device allows running higher boost safely by tricking the ECU into lower pressure readings while maintaining precise fuel delivery.

- Pneumatic Solenoid Design: Direct boost-referenced operation without electronics for consistent performance under extreme conditions
- 3 x 1/8 NPT Ports: Standard fittings ensure straightforward plumbing into vacuum boost lines and regulators
- Brass and Aluminum Construction: Durable materials resist corrosion and handle high pressures up to 50 psi continuously
- Compact Size: Measures 2.2 x 1.5 x 1.2 inches weighing just 2.4 ounces for easy mounting in tight engine bays
