PP Rear Bumper Blade Diffuser & Back Side Splitter fits for Mazda 3 Hatchback BP 2019+

▎Fitment & Compatibility

This rear set is designed specifically for the 2019, 2020, 2021, 2022, 2023, 2024, 2025,2026 Mazda 3 Hatchback, following the rear bumper line for a precise, vehicle-matched fit.

▎Structure & Coverage

This is a combined rear package, not a single piece: a rear blade diffuser that runs along the centre of the rear bumper, plus left and right rear side splitters that carry the line out to the bumper corners.

That combination is what makes the rear read as one designed unit. A diffuser on its own stops at the bumper edges and leaves the corners looking bare — the side splitters continue the line out toward the wheel arches, so the car looks wider and lower from behind and from a three-quarter view.

▎Design & Appearance

Designed to extend the rear bumper's lower line and give the Mazda 3 Hatchback a wider, more planted rear stance. Because the diffuser and the side splitters are shaped as one family, the finished result reads as a factory-optional rear package rather than separate bolt-on parts.

▎Installation

This rear set is designed for straightforward installation using automotive-grade double-sided adhesive tape and/or mounting screws, providing a secure fit without removing the rear bumper or making heavy modifications to the original bodywork. Clean, degrease and warm the surface before applying tape — on trim parts of this type, most adhesion failures in the field trace back to surface preparation rather than the tape itself.
