Anybody got one? it's the one in under the bumper below the headlight on the driver side. thanks!

 

Air pump?

 

An air pump pushes clean air into the exhaust side of the engine to help complete the burning of any products of incomplete combustion when the engine is warming up. s2000s have two O2 sensors in the exhaust system, not pumping clean air may affect how those sensors will read, resulting in issues that might not otherwise arise. Youll find it behind the bumper on the drivers side

 

also helps heat up teh o2 sensors faster i heard.

 

You're in Alberta. Rip all that garbage emissions stuff out.
