Honda Civic EK4 Tuning Packages

Stage 1 Package Up to 5BHP

AEM/Fujita cold air Intake £295 + Vat

Our stage 1 package for the EK4 Civic concentrates on freeing up the intake in order to make your B16 breathe more easily. The addition of a cold air intake provides great gain in combination with outstanding value for money. We have often found that the CAI gives better mid range response than the much more sizeable Mugen intake, which although it delivers marginal top end power gains, is much more expensive even for the replica found in the market even for the replica found in the market.

Stage 2 Package Up to 10BHP

Stage 1 + Exhaust catback (DC Sports Stainless Steel Manifold) From £685 + vat

Our stage 2 is a stage 1 +, it will free up the intake AND the exhaust system, changing the tone of the B16 into a more aggressive growl.

Stage 3 Package Up to 15BHP

Stage 2 + Exhaust manifold + decat From£1145 + vat

The stage 3 tuning package for your EK4 concentrates on further improving flow through the engine in order to increase its volumetric efficiency, allowing even greater power gains. To do this we concentrate on freeing up the exhaust path using DC sports products, which provide similar gains to TODA systems, but offering much greater value for money.

Stage 4 Package Up to 20BHP

Stage 3 + remap From £1595 + vat

This is the last stage without having to start work on the engine internals

At Eurospec we can remap your Civic EK4 using eCtune software to develop a custom map for your car. We use a chipped OBD1 ECU (Honda 92-95) with a custom conversion harness to enable the ECU to run your car and then we burn the custom map we've developed for your individual car onto it.
