Step 1: Gather the Necessary Tools

• Scissors: Used to cut 3M tape into slices for easier application.
• Included Double-Sided Tape: Provided in the package, but we also recommend using 1-inch wide 3M tape for a stronger bond.
• Screwdriver or Drill: Required for securing the diffuser with the included screws.
• Another Person: Having an extra set of hands will make installation easier and more precise.

Step 2: Clean and Prep the Installation Surface

• Ensure the application surface is free of dirt, dust, or grease.
• Wipe down the Diffuser to remove any residue or contaminants.
• Make sure the surface is completely dry and cool before proceeding with installation.

Step 3: Prepare the Rear Diffuser

• We highly recommend using a 1-inch wide roll of 3M tape for additional adhesion.
• Cut multiple pieces of 3M tape and apply them evenly along the edges of all three diffuser sections.

Step 4: Align and Install the Diffuser

• Peel off the tape backing: Remove the backing from the 3M tape applied to the diffuser.
• Start with the middle piece: Align the center section of the diffuser with the stock diffuser. - Ask someone to hold it in place while you begin securing it.
• Secure with screws: Drill the screws through the marked locations on the diffuser and into the stock panel. - Ensure the screws are evenly spaced for proper stability.
• Attach the side pieces: Repeat the same steps for the left and right side pieces. - Make sure both side pieces align correctly with the middle piece for a flush and secure fitment.

Final Inspection

• Check that the diffuser sits securely and evenly aligned with the stock panel.
• Press along the taped areas to reinforce adhesion.
• Ensure all screws are properly tightened, but do not overtighten to avoid damage.

Post-Installation Guidelines

• Do not wash the car or expose it to extreme conditions for 24 hours to allow the adhesive to fully cure.
• Periodically check the screws and tape to ensure the diffuser remains secure over time.
