These instructions were written with a 2018 Honda Civic Type R.

Remove the five (5) 10 mm bolts circled in orange with a 10 mm deep socket and ratchet and then remove the engine cover

Loosen the nut with a 10mm deep socket and ratchet then remove the Negative cable from the battery. Tuck the cable out of the way

Loosen the nut with a 10mm deep socket and ratchet then remove the Positive cable from the battery. Tuck the cable out of the way

Loosen the nut (red circle) with a 10mm deep socket and ratchet then remove the hook and battery tiedown from the battery

With the cables and tiedown out of the way lift the battery out of the engine bay and set it to the side

Note that there may be a handle on your battery that makes removal easier

Remove the battery foam and tray case to reveal the battery bracket.

Remove the 2 bolts with a 10 mm deep socket and ratchet and set them aside.

With needle nose pliers pinch the clip and push it out of the bracket

Remove the nut behind the engine that holds the plastic cable assembly in place with a 10 mm deep socket and ratchet and set it aside

The entire plastic cable assembly should now be loose. This should make removing the battery bracket easier in the next step

There are three (3) 12mm bolts that must be removed on the top

There are two (2) 12mm bolts underneath the bracket that must be loosened. The second picture shows the bracket out of the car to make finding the blind bolts easier

With the upper bolts removed, the lower bolts loosened, and the plastic cable assembly loose, the bracket can now slide up and out of the engine bay

Unplug the Map Sensor and set the wire harness out of the way

With a 12mm socket and ratchet remove the two (2) bolts, circled in orange, and set them aside

Pinch the hose clamp with needle nose pliers and remove the hose from the charge pipe

With a 10mm socket, extension and ratchet loosen the two (2) hose clamps

Alternatively if you don't have a long enough extension then you can use a long Philips head screw driver

With the clamps loosened you should now be able to pull the charge pipe toward the side of the car and remove the OEM throttle body tubing

Loosely place the 67-75 clamp on the smaller side of the silicone. Orientate the 67-75 clamp as shown

Loosely place the 76-84 clamp on the larger side of the silicone. Orientate the 76-84 clamp as shown

Orienting the clamps as shown is necessary to avoid any potential contact or rubbing during engine movement

Install the throttle body silicone so that the logo is facing up

The smaller side of the silicone is connected to the charge pipe and the larger side of the silicone is connected to the throttle body

With a 10mm deep socket and ratchet tight the two clamps

Plug the wire back into the sensor

Install the two 12mm bolts back into the charge pipe with a 12mm socket and ratchet

Hook the hose back up to the stem with a pair of needle nose pliers

Partially start the two lower 12mm bolts by hand. The battery bracket will rest between the washer and the engine bay

Set the bracket into the engine bay and make sure the lower part is resting on the two lower bolts

With the bracket in place, install the 3 upper 12mm bolts with a 12mm socket and ratchet

With a 12mm socket, extension, and ratchet tighten the two lower bolts

Hook the plastic cable assembly back on the stud and reinstall the 10mm nut with a 10mm deep socket and ratchet

Reinstall the two 10mm bolts

Reinsert the clip into the battery bracket

Place the battery tray and foam on top of the battery bracket

Set the battery on the tray and in the foam

Install the battery tie down

The long rod hooks to the battery tray

Install the 10mm nut onto the long rod,. Tighten with a 10mm deep socket and ratchet

Place the positive wire back on the positive terminal

Tighten the nut with a 10mm deep socket and ratchet

Place the negative wire back on the negative terminal

Tighten the nut with a 10mm deep socket and ratchet
