Oil Pressure Sensors

Oil Pressure Sensors: read what the engine is actually doing

An oil pressure sensor takes the pressure in your oil galleries and turns it into a signal your gauge or ECU can read. Fit one when you want a real number instead of an idiot light, or when a standalone ECU needs a live feed to trigger protection strategies if pressure drops. Most of the oil pressure sensors here thread into a sending-unit port or a remote-mount block, wire back to a gauge or ECU, and let you catch a failing pump or a bearing problem before it grenades the motor. On a build, they are cheap insurance.

What ThreePiece stocks

This category currently shows 6 products from 4 brands: Haltech, AMS, Bosch and Nitrous Express. Prices run from $41 to $224 for what is in stock right now - that is the live range, not a fixed price. Haltech accounts for three of the sensors, including the Haltech 150 PSI TI pressure sensor (HT-010904) and the higher-range Haltech 250 PSI TI sensor (HT-010906), both listed as fuel/oil/wastegate units. At the lower end sits the Bosch Volkswagen TDI intake manifold pressure sensor, and for nitrous plumbing there is the Nitrous Express 0-100 PSI pressure sensor.

How to choose

Start with the pressure range. The Haltech TI sensors read to 150 or 250 PSI, so if you want headroom above what a stock oil system sees, the 250 gives it; the 150 stays higher-resolution over a narrower band. Match the range to the job - oil, fuel or wastegate - and to what your gauge or ECU expects. If you need a clean install away from a hot cylinder head or crowded valley, the AMS Performance remote-mount sending unit line kit relocates the sensor on a line, which is the smart move on a tight engine bay. Budget-minded and just replacing a signal? The Bosch unit is the least expensive option here. Confirm thread size and connector before you buy.

What else you need with it

A sensor rarely goes in alone. You'll likely need adapters and fittings to thread it into the right port or line, and if you're already in the oil system it's worth checking oil filters. Building the bottom end at the same time? Look at bearings and pistons. All of these sit under the broader engine components section.

Fitment and ordering

Only one product in this group carries model-specific fitment data - the AMS kit lists Mitsubishi EVO applications across roughly 2001-2007. The Bosch part names a Volkswagen application in its title. The Haltech and Nitrous Express sensors are sold by pressure range and port, not by vehicle, so check the specs against your setup. If you're unsure, call fitment help at 813-535-5801 or reach us through contact us. Every order ships free, and Affirm and Katapult financing is available at checkout.
