The Holley EFI 554-203 Boosted Sensor Kit is a sensor package for boosted engines. It steps up from the street kit with a 3.5 bar stainless steel MAP sensor in place of the GM 1 bar sensor and two 0-200 PSI pressure sensors in place of the single 0-100 PSI unit. Buying the sensors together gives a data-logging or EFI system a matched set of inputs without sourcing each sensor separately.

- Kit includes: Coolant Temperature Sensor (534-10), Intake Air Temperature Sensor (534-20), (2) 0-200 PSI Pressure Sensors (554-103), 3.5 Bar Stainless Steel MAP Sensor (554-134)
- Pressure sensors use 3/8 in. NPT threaded mounting
- Blade-style electrical terminals
- Wiring harness, mounting brackets and mounting hardware are not included
