If you are installing this MMD Hood Scoop on a car that already
has a GT Scoop, remove the GT Scoop and skip to Step 5 of this
installation guide.

STEP 1 // Open the hood and remove the 11 plastic retaining pins securing the hood insulation
pad. A trim removal tool works best for this job, but a flat head screwdriver can be used. Once all
of the clips are removed, set the insulation pad aside.

STEP 2 // Using an X-Acto knife or sharp razor blade, cut out the two sections of the drill template on the OUTSIDE of the black lines as

STEP 3a // Install the lower template first by lining it up on the edge of the factory scoop and along the two outside edges as shown.

STEP 3b // The upper template is installed on the
upper edge of the factory scoop, using the
dotted center line as a guide (this dotted line
should be matched with the dotted line on the
lower template).

Note: Do not drill the lower center hole when
installing this MMD Hood Scoop.

STEP 4 // Center punch the 6 holes and drill up to a 3/8” hole. (It may help to step up gradually to 3/8” by using 3/16” then 1/4” bits) When
finished, remove the drill templates and clean any leftover fiberglass shavings using a Shop Vac.

STEP 5 // Before installing any adhesive tape, use the supplied alcohol pads to thoroughly wipe down the tape ledges on both the scoop & insert. Once the alcohol is dry, follow with the supplied 3M Adhesion Promoter. Place tape on
the scoop as shown, along with the 6 clip studs.

STEP 6a // Install the 4 pieces of tape to the top of the insert and install on the underside of scoop as shown.

STEP 6b // Once attached to the insert, place the remaining 3 pieces of tape on the underside of the insert.

STEP 7 // Peel the backing from the adhesive tape and place the scoop on the hood aligning the rear studs first. Don’t fully press down on the scoop until all studs are properly located and the scoop is in its desired location. Once it is properly aligned, move around the edges and
firmly press down to fully seat the adhesive.

STEP 8 // Install the washers & nuts on the underside of the hood using a 7mm socket. Just tighten until snug, over tightening the nuts could
possibly damage the hardware.

STEP 9 // Once all 7 sets of washers & nuts are
installed and the scoop is secure, re-install the
hood insulation pad removed in Step 1 to
complete the installation.
