The best TPMS sensors for a Subaru are direct-fit 315 MHz sensors made for your model, and that is exactly what this collection carries: Schrader TPMS sensors listed for the WRX, WRX STI, Legacy, Forester, Outback, and Crosstrek, plus a snap-in 315 MHz Subaru version and a 315 MHz sensor covering Lexus, Scion, Subaru, and Toyota. Match the sensor to your year and model before ordering, because TPMS fitment is vehicle-specific.
A tire pressure monitoring sensor lives inside the wheel and reports pressure to the car. When a sensor battery dies or a sensor is damaged during a tire change, the warning light stays on until the sensor is replaced and relearned. Look for the correct frequency — the sensors here are 315 MHz — the correct valve style, including the snap-in version listed here, and a fitment listing that names your vehicle.
Schrader is the only brand in this collection, and its listings here are focused entirely on TPMS sensors rather than general tire hardware. The range covers Subaru cars and crossovers in one listing, a separate snap-in 315 MHz Subaru sensor, and a shared 315 MHz listing for Lexus, Scion, Subaru, and Toyota. That focus makes Schrader the straightforward pick when the job is replacing a failed sensor instead of shopping a whole wheel package.
McGard is the wheel-hardware companion most sensor shoppers also need, known for lug nuts and wheel locks that protect the wheels those sensors sit inside. A tire or wheel change is the natural time to inspect both sensors and lug hardware together. Browse McGard if your lug nuts are corroded or you want locks on a new wheel set.
Project KICS covers performance lug nuts and wheel hardware for drivers who change wheels for the street and track. Like McGard, it pairs with a sensor purchase because the wheels have to come off either way. See Project KICS for its hardware range, and shop the matching rubber in Tires and Wheels.

How do I know which Schrader sensor fits my Subaru?
Start with the fitment named in the listing: one sensor covers the WRX, WRX STI, Legacy, Forester, Outback, and Crosstrek, while the snap-in version is listed for Subaru at 315 MHz. If your exact year and trim are not clear in the listing, check your year and model before ordering.
Does a new TPMS sensor need programming or relearn?
Most vehicles need a relearn procedure after a sensor is replaced so the car recognizes the new sensor ID. A tire shop can normally complete the relearn during installation. Ask your installer what your specific model requires.
When should a TPMS sensor be replaced?
Replace a sensor when its battery has died, when it is physically damaged, or when the TPMS light stays on after pressures are confirmed correct. Many owners also replace sensors proactively when fitting new tires, since the wheels are already off.
Can I install a TPMS sensor myself?
The sensor mounts inside the tire, so installation requires breaking the tire bead and rebalancing the wheel. Most drivers have a tire shop handle the install and relearn together rather than attempting it with hand tools at home.
