BMW G8X M3 and M4 Parts

G8X covers the current M3 and M4: the G80 sedan, the G81 Touring, the G82 coupe and the G83 convertible, built from 2021 onward. All of them use the S58 twin-turbo inline-six, and mechanically they have far more in common with each other than the four different body styles suggest. A part cut for a G80 engine bay almost always fits a G82, which is why they are grouped here.

What we stock for the G8X is the S58 range: 3.5-inch downpipes, a front mount intake and an oil cooler guard. The downpipes are the only one of the three that changes emissions equipment, and they are sold for off-road and competition use only and need a tune. The intake and the guard need neither, and both ship to every state.

Bumper cuts and cooling layouts do differ slightly across the four body styles and across the facelift. Every listing shows the chassis codes it is confirmed for. Where that list is still being verified, the product page says so plainly rather than leaving you to guess.
