EK4 and EK9 are model designations for two of the high performance versions of the sixth-generation Civic produced by the Honda Motor Company. Both are hatchbacks; the EK4 was the Japanese domestic market Civic Sir, while the EK9 was the Japanese domestic market Civic Type R. As neither of these models were sold in the United States, they are highly prized by Honda fans throughout North America.

EK Generally

EK is the general chassis code for the sixth-generation 1996 to 2000 Honda Civic. The vehicle was sold worldwide, but certain models were restricted from certain markets, such as the unavailability of the hatchback Civic variants in the United states; Honda offered a Civic coupe in these years, but did not bring the hatchback to the United States. Honda produced eight sixth-generation Civic variants with either a EK, EJ or EM designation.


EK4 is the chassis code for the Japanese domestic market 1996 to 1998 Honda Civic Hatchback Sir. The EK4 came equipped with the B16A engine, a five-speed manual transmission, and was the basis for the EK9, which was a modified EK4.


EK9 is the chassis code for the Japanese domestic market 1999 to 2000 Honda Civic Hatchback Type R. The very top of the performance line-up, the EK9 came equipped with the B16B engine. One easy way to visually distinguish EK9 variants is they came equipped with five-lug wheels, as opposed to the standard four-lug wheels.

Additional EK9 Improvements

In addition to the fitting of the B16B engine, the EK9 received body and shell reinforcements, larger brakes, a limited slip front differential, a quicker steering rack ratio --- to improve steering response --- and a more sporting suspension. Interior modifications including Recaro brand seats, a Momo brand steering wheel and a titanium shift knob. A front lip spoiler and rear wing along with smoked headlights completed the EK9 package.
