We recommend servicing the valve every 3 years or 20,000 miles, whichever comes first.
The Forge Motorsport blow-off valve-style adaptor plate is designed for the 1.4 Multi-Air Turbo engine. It is installed in combination with the original solenoid valve and creates the characteristic sound of venting or releasing boost air.
The kit includes:
- 1 × FMSPF14A adaptor
- 3 × M6 × 35 socket head screw
- 1 × Forge sticker
Suitable for: Fiat 124 Spider I (348), Fiat 500 II (312).
