Why Install Custom Grilles?

Custom grilles add a sleek, aggressive look to your car while improving airflow. This guide walks you through installing expanded steel mesh grilles, perfect for enthusiasts wanting a rugged, personalized front end.

Tools & Materials

Item	Purpose
Expanded Steel Mesh	1/4″ thickness (available at welding shops).
Tin Snips/Dremel	Cutting mesh and trimming plastic.
Screwdrivers	Phillips and flathead for bumper removal.
8mm & 10mm Sockets	Remove bumper bolts.
Liquid Nails Adhesive	Secure mesh without welding.
Rustoleum Paint	Durable finish (primer + color + clear coat).
Cardboard	Create templates for precise cuts.

Step 1: Remove the Bumper

Pop plastic plugs: Use a flathead to remove 8 plugs along the top grille.
Unscrew bolts:
- Fender wells: Two 8mm screws per side.
- Underside: Four 10mm bolts (two center, two outer).
Gently pull the bumper forward and set it on a soft surface.

Step 2: Disassemble Factory Grilles

Upper grille: Remove screws on the back, then separate the two plastic pieces.
Lower grille: Cut horizontal/vertical supports with a Dremel or razor knife.
- Pro Tip: Keep the license plate bracket if required in your state.
Brake ducts: Carefully cut plastic ducts with a razor knife. Go slow to avoid gashes!

Step 3: Create Mesh Templates

Trace openings: Use cardboard to outline grille and duct shapes.
Transfer to mesh: Add 1–2″ tabs around edges for securing.
Test fit: Trim as needed until mesh sits flush.

Step 4: Prep & Paint the Mesh

Clean thoroughly: Scrub with Simple Green and a wire brush.
Paint:
- Apply 2–3 coats of Rustoleum primer.
- Follow with 8–10 coats of color + clear coat.
- Let dry 24 hours.

Step 5: Install Custom Grilles

Upper Grille

Sandwich mesh between factory grille halves.
Secure with original screws.

Lower Grille & Brake Ducts

Bend tabs: Hook mesh tabs around bumper edges.
Glue: Apply Liquid Nails to tabs and press firmly.
Screw: Add 1/2″ screws to lower grille for extra hold.

Step 6: Reattach the Bumper

Reinstall styrofoam support: Secure with electrical tape.
Bolt bumper back: Reverse removal steps.

Pro Tips for Success

Avoid Rust: Use rust-resistant paint and seal edges.
Patience Pays: Let adhesive cure 24 hours before driving.
