ScienceofSpeed Factory Oil Pressure Sensor Upgrade Kit - NSX, 1991-99


Have you noticed your factory oil pressure gauge performing erratically or not reading at all? This is common - and in most cases - is not the gauge itself, but the engine-mounted sensor. Vibration from the engine causes the factory pressure sensor to fail.

ScienceofSpeed has addressed this problem by not only upgrading the sensor itself but creating a relocation kit that removes the sensor from the engine and mounts it to the firewall. This is the perfect replacement for the factory sensor which is discontinued.

The kit includes a custom calibrated sensor that matches the factory sensor's output. This sensor exceeds SAE guidelines for sensor vibration resistance. The factory cylinder head cast mounting elbow is removed and replaced with a billet machined aluminum block. This block allows the included braided stainless steel line to be installed. The sensor is tucked away behind the coolant expansion tank, out of sight, to retain the OEM look of the engine bay. The sensor fits behind the factory and aftermarket coolant expansion tanks. The sensor kit allows the factory plug to be used from the factory sensor - no cutting of the factory engine harness required.


  • Kit includes pressure sensor, billet pressure sensor plate, new factory o-ring, high pressure hose, mounting clamp, fasteners, & electrical harness.
