On first view the EE9 Civic and EF9 Civic counterpart look the same except for the EF9 being right hand drive and the EE9 left hand drive (except for british models), but there are more differences that set them apart. There are bigg and small differences like for example the Horsepower of both cars, the EE9 has a stock 150Hp B16A1 engine while the EF9 has a 160Hp equipped B16A, both B series are the same but the EE9 lacks a knock sensor and was detuned for the European market which had different Octane levels in their fuel (95RoN and 98RoN) while the Japanese domestic market supplied fuel with 100RoN. We'll show you a detailed picture comparison between these two 4th generation Civic VTEC models in the following pages based on the biggest differences so not all the options that were available for this car and the standard Civic 88~91. I'll point you to this page in our gallery to see the full range of options.
