It supports the 1.6 and 1.8 model from the same hardware, and also fits the OEM case, which means the conversion installs tidily into the OEM position. The only extra thing you need to do besides plugging it in is run a MAP vacuum hose (supplied) from the ECU to the intake manifold.

Please note that if you are using a switched type TPS sensor as fitted to the 1.6 model, we suggest installing a variable TPS to give better throttle response – the 1.8 model already has the variable TPS as standard. Also, if you wish to run without a MAF sensor, then you will need to install an Intake Air Temperature Sensor – available in the options list.
