Here at Brewed Motorsports we most often use the AEM 5 BAR map sensor as they have proven to last longer and be more reliable than the Omni power MAP sensors. The AEM 5 bar map sensor also comes with a barb fitting and a -3 an fitting which allows you to remote mount the sensor away from the engine. This further increases the life of the MAP sensor and provides a super clean noise free signal to the ECU. AEM 5 Bar MAP sensors are in stock and available from the link below for anyone that needs.
