A spoiler would be a sleek accessory to your Honda Accord's trunk. Not only will it give your vehicle a more aggressive flair, but for applications on the track, it can provide the added downforce to supplement traction and handling. There's a wide variety of aftermarket spoilers available for the Honda Accord, all of which follow similar instructions. Here's the DIY guide to install a spoiler on your Honda Accord today.

Materials Needed

Spoiler kit
Drill and drill punch
8 and 10mm drill bits
Flat head screwdriver
Felt tip pen
Cleaning putty
Pliers
Zip ties
Trunk spring removal tool

Step 1 – Remove the trunk liner

Honda Accords that are not manufactured with a factory spoiler have rubber grommets in the spoiler mounting locations. Once you remove the trunk liner, the areas for the pilot holes will be made visible.

Disconnect the negative (black) terminal of the battery.
Open the trunk, and use pliers to remove the clips around the trunk liner.
Pull the liner out.
Locate the rubber grommets underneath the trunk lid, and remove them.
Mark the rubber grommet area with a drill punch.

Step 2 – Drill the mounting bolt locations

With an 8mm drill bit, drill holes through the punch marks. Make sure to hold the drill straight and steady.
To clean off the holes with pliers, remove the nips of protruding metal.

Step 3 – Mark the wire harness location

Grab the mounting template from the spoiler kit.
Place it over the edge of the trunk lid, so the holes of the template line up with the mounting bolt holes.
With a felt tip pen, mark two additional holes on the trunk lid through the mounting template.
Drill an 8mm hole through the mark closer to the rear windshield. This hole is for an additional mounting bolt.
Drill a 10mm hole through the mark closer to the rear of the trunk lid. This hole is for the wire harness.

Step 4 – Mount the spoiler

Smear some cleaning putty onto the drill holes.
Line up the spoiler over the mounting bolt holes.
Snake the spoiler's wire harness through the 10mm hole.
Position the spoiler directly onto the trunk lid, so the mounting's bolt holes line up with the spoiler's bolt holes.
Fasten three 8mm bolts to the spoiler. Tighten the bolts to a snug fit.
Mount the other end of the spoiler.

Step 5 – Replace the trunk springs

The older trunk springs were manufactured to handle a particular trunk weight. They must be replaced with heavy duty springs to accommodate the extra weight from the spoiler.

Place the open-end of a trunk spring tool under the upper trunk spring, and connect the closed-end of the trunk spring tool to the end of the lower trunk spring.
Pull up on the trunk spring lever to gain leverage, and to safely remove the spring.
Use the trunk spring tool to install the new heavy duty trunk spring in the reverse order to the removal process.
