Will this cover my fog light cutouts?

This bumper is molded to I-Spec proportions and retains factory fog light openings. You'll need to cut or drill holes to match your existing lights if they don't align with the molded voids.

Can I install this without removing the whole front end?

Most installers unbolt the stock bumper and bolt this one on using the same mounting points. You don't need to drop the radiator or remove other panels, but access depends on your toolkit and experience.

Does this work if my bumper has sensor cutouts?

Stock sensor holes won't carry over automatically. If your car has parking sensors or other electronics in the OEM bumper, you'll need to drill matching holes in the right locations before or after paint.
