Brand new genuine Bosch replacement Oxygen (O2) sensor. Works in upstream and downstream positions.
2005+ Elise, Exige, 2-eleven All 4-cylinder
2009+ Evora All
2012+ Exige V6 All
Replaces upstream (pre-cat) or downstream (post-cat) sensor.
This is an OEM quality direct replacement sensor. It has the same response characteristics and output scaling as your original sensor and will not cause a check engine light. It does have a universal type wiring connection so you must simply cut the connector from your old sensor and splice it on to this sensor using the provided premium weatherproof shrink crimp connections. A couple minutes of work is well worth it – new sensor from Lotus lists for $205.
