Prices range from around £50 for an after market part without the connector attached to £70 for one with a connector to £150+ for a Lotus branded unit from a main dealer.

Do not be tempted to use a (cheaper) S1 sensor on an S2 and splicing the wires. The S2 [[ECU]] will turn on the MIL because the heater element resistance value is different between the two sensor types and the S1 sensor falls outside the allowable range for the S2 [[ECU]].
