Do these vents require drilling or cutting into my fender?

No. These vents are designed to use your vehicle's existing fender opening structure. You'll mount them directly to the panel without modification. Verify your fender opening dimensions against the vent profile before ordering to ensure a clean fit.

What fasteners do I need to install these?

This kit includes the vents only. You'll need to source fasteners suited to FRP mounting — self-tapping screws or stainless hardware work well. Consult a local hardware supplier for recommendations based on your fender material and thickness to ensure a secure, weather-tight installation.

Can I install these vents in stages, or should I paint them before bolting them on?

FRP is easier to prep and paint off the vehicle. Sand and prime both vents before installation, then final-coat them once mounted and cured. This avoids overspray on your fender and gives you cleaner lines where the vents meet the panel.
