Will this interfere with the trunk seal or factory bumper cover?

This diffuser is designed for under-bumper mounting and clears the stock trunk seal. Verify your vehicle's bumper attachment points before installation to confirm clearance with any factory reinforcement ribs or brackets.

Does this require drilling into the bumper or body panels?

This piece integrates with existing factory mounting locations. No modification to the vehicle's core structure is required, making installation straightforward for DIY work with basic hand tools.

What prep work is needed before painting?

Sand the entire surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove dust. Apply your primer and topcoat according to your paint product's instructions for best durability and finish quality.
