Will this fit my bumper if it has parking sensors?

This molding is engineered around factory sensor cutouts on E46 bumpers. If your bumper has OEM sensors, the geometry should accommodate them — but inspect the cutout pattern on your specific bumper before final installation to confirm alignment.

Do I need to paint this before installing?

The trim ships primed and ready for paint. Sand to your preferred grit, apply primer if needed, and paint to match your bumper color before bolting on. Test-fit first to catch any fitment issues before committing to paint.

What hardware do I need to mount it?

Mounting hardware is not included with this trim. You'll use the existing fastener points on your bumper assembly — refer to your E46 service manual for torque specs and hardware sizing to match your setup.
