Each kit also includes our vacuum block set. A vacuum block combines the vacuum signal from all four throttle bodies into one stable source, making it ideal for MAP sensors, fuel pressure regulators, brake boosters, boost gauges, and other vacuum-operated accessories. This provides a smoother, more consistent vacuum signal compared to connecting to a single throttle body.
Built for enthusiasts who demand precision, performance, and flexibility.
