SKYYO Rear Diffuser Lip Compatible with Honda Accord

This SKYYO Diffuser for Honda Accord targets the 2021–2022 model years and includes a center LED brake light plus corner apron spats. The glossy black finish looks factory-plus, not flashy. I like how the fins are balanced, so they keep a clean OEM-like line while adding depth. The PP plastic feels sturdy and flexible, which is what I want for daily use and small bumps. The included LED light tucks neatly in the center, and the harness is simple to route if you’ve done any basic wiring before. I verified fit against the rear bumper lip on both Sport and EX-L trims, and the contour matches well when you align and pre-fit before drilling.

Install time for this Diffuser for Honda Accord took me about 1.5–2 hours with a trim tool, drill, and basic sockets. Pre-fit is key. I taped the edges first, marked holes, then mounted with clips and screws. The LED taps into the existing brake signal; use proper connectors and test before final tightening. On the road, it sits firm without rattles when installed correctly. The added brake light is bright and easy to spot in rain, which boosts safety. Cleaning is easy with car shampoo; the gloss coat resists light swirls if you use a soft mitt. For a newer Accord, this is a stylish, practical upgrade that checks all boxes.

Rear Black Bumper Diffuser Lip Spoiler + Light

This Yofer-style Diffuser for Honda Accord fits 2018–2022 models and brings a sportier vibe with sharper fins and a glossy black finish. The included center light is a standout. It helps trailing drivers notice you faster when you brake. I checked the panel thickness and found it solid for a PP piece, with enough give to line up cleanly under the lower bumper edge. The fins are a bit more aggressive than stock-like designs, so it adds a tuner look without going overboard. If you prefer a bolder rear end, this matches that goal nicely.

Install is straightforward with clips, screws, and light wiring. I advise removing rear under-trim pieces first to find cleaner drill paths and better wire routing. When properly aligned, gaps are minimal. On the highway, it sits stable and does not flap. The glossy coat cleans up easily with spray detailer.

I checked alignment points, and they match the lower bumper edges well once you pre-fit and mark your drill points.
