The Aeroflow Performance Pressure Sensor Block is a must to protect your transducers from harsh engine vibrations, shock loads and heat leading to premature failure to the sensitive internals of the modern-day pressure sensor when mounting directly to engine blocks. To prolong the life and reliability remote mounting these sensitive pressure sensors is recommended to improve service life and reliability. This block will allow you to remote mount up to 3 sensors with 3 x 1/8" NPT and 10 x 1/8" NPT for input line configurations. This makes it perfect to improve engine bay organization by neaten up wiring, plumbing and bringing all the sensors to one location for easy maintenance. Compatible with all transducers that utilize 1/8" NPT male threads and7/8" or smaller body / hex diameter.
