Toyota O2 Sensor Extensions (2-4week Lead Time)

You asked, we listened! Custom Toyota O2S extensions with OEM style waterproof connectors, hand built wiring here in house, with a race level fire sleeve outer wrap to protect your sensor wires up to 2000F intermittent temps, sold by the pair. 

These are built to last, and while we offer specific set lengths for upstream with headers, and downstream with headers + factory cats, we can build these to any length. Just ask! Or head to our build-to-length O2S product page to have us custom build your perfect set!

For the First Gen Tundras, there is some variance on lengths so we will reach out for a real time measurement off your truck to build these perfectly for you. 

For FGTs with LT headers, access cabs usually land around 30in extensions, double cabs typically land in the 36in ballpark for upstream lengths.

Downstreams can range a lot depending on factory vs aftermarket cats, no cats, or where cats are welded into the system.
