Does this need to be painted, or does it come ready to install?

The grille comes in black hard panel finish ready to bolt on as-is. If you want a different color to match your bumper, sand it lightly and apply your choice of paint or coating before installation.

Will the LED DRL work straight away, or do I need to wire them up?

The LEDs are pre-wired into the assembly. You'll connect them to your vehicle's existing DRL power source or run a dedicated line—no soldering or custom harness building needed. Your local shop can handle the connection in under an hour if you don't want to DIY it.

What fasteners do I need to bolt this on?

The grille mounts at your factory bumper attachment points. Bring your torque wrench and check your service manual for the correct fastener specs—hardware is not included, but you likely have what you need in your existing hardware kit.
