1996-2000 Civic CX/DX/LX Cold Air System Installation Instructions

Read and understand these instructions BEFORE attempting to install this product.
1) Disconnect the negative battery terminal.
2) Make sure the engine is cool enough to drain coolant from the radiator.
3) Raise the vehicle and support on properly rated jackstands. a) Remove the front lower splash shield. (Fig 1) b) Loosen the passenger-side fender well liner and move sufficiently to gain access to the area immediately behind the front bumper. This is where the air filter is going to be installed. (Fig 2)
4) Loosen and remove the resonator hold down bolts. (Fig 4) a) After removing the bolts, remove the air inlet duct from the air filter case on the throttle body.
5) Removal of the inlet air temperature sensor and filter case. a) Remove the breather hose from the base of the filter case and the from the cam cover (Fig. 5). b) Disconnect the water bypass hose from throttle body or the fast idle thermo valve, where equipped, located at the lower portion of the throttle body. Disconnect the opposite side of the water bypass hose, which runs to either the intake manifold or the water outlet neck. Remove the entire water bypass hose and breather hose assembly from the vehicle. c) Loosen and remove the bottom bolt that holds the filter case to the throttle body (Fig 6). d) Remove the inlet air temperature sensor from the filter case and set aside for re-installation later (Fig 6). e) Loosen the clamp at the base of the filter case and lift the filter case out of the engine bay. i) The harness for the air temp sensor is attached to the base of the filter case. Remove the harness from the support before you pull the filter case away.
6) Install the main air pipe. a) The end of the primary air pipe with the breather tube and IAT sensor grommet attaches to the throttle body. b) The bracket at the inlet end of the primary pipe will line up close to a bolt that secures a wire loom bracket to the shock tower. Remove the bolt and install the rubber isolator mount supplied with the kit into this threaded hole. c) Install the supplied rubber grommet and inlet air temperature sensor into the primary inlet pipe. Reattach the wire harness for the inlet air temperature sensor. d) Install one of the black connector hoses onto the end of the pipe that attaches to the throttle body. Also install two hose clamps onto the connector hose.
