Two Cones for the Twin-Turbo M
The S58 is a ferociously capable twin-turbo six, and this open system is built to let it breathe as hard as it pulls. A dual-cone S58 intake replaces the sealed factory box with a pair of exposed high-flow filters, opening the path to the turbos and freeing the engine to draw air properly. Better still, it comes with the reassurance of a parts certificate for road use.
Why Two Cones
The twin arrangement is not for show. A G80 M3 intake of this design uses two filters so each side of the induction path draws freely, matching the engine’s healthy appetite without one shared element becoming a choke point. It is a layout chosen to flow, giving the turbos all the air they can use rather than restricting them behind a single filter sized for quiet running.
Cooler, Freer Air
Open does not have to mean hot, and a good dual cone intake manages both. Freed from the restrictive factory box, the filters draw more air, while shielding and ducting help keep that air cool on its way to the engine. Cooler, denser air is better for combustion, so the engine makes the most of every breath, and the open design lets it do so with a purposeful induction sound the standard airbox hides.
Sharper, More Eager Response
The change you feel first is in how the engine answers. A BMW M3 intake of this kind sharpens throttle response and lets the six pull with more urgency, the restriction of the sealed box simply gone. It makes an already thrilling engine feel even more alert.
Road-Legal With a Certificate
This is where it stands apart from many open intakes. A G80 intake supplied with a parts certificate is approved for road use, so you gain the performance and sound without the worry of an inspection problem. For owners who want a genuine upgrade that still passes muster legally, that certificate is as valuable as the hardware itself, taking the risk out of fitting an open system to a car used on the road.
A Pair of High-Flow Filters
The heart of the kit is the filtration. With S58 intakes built around two quality high-flow filters, the system protects the engine while flowing far more freely than the paper panel in the standard box. Many such filters are reusable too, cleaned and re-oiled rather than replaced, so the airflow stays consistent over the long life of a car kept and enjoyed.
The Voice of the Six
Half the pleasure of an open intake is the sound. A BMW M4 intake of this type uncovers the hard, urgent induction note of the twin-turbo six that the sealed box keeps muffled, giving the car a voice to match its performance.
For the M2 As Well
The smallest of the trio is no exception. A BMW M2 air intake of this design brings the same freer breathing and sharper response to the compact M car, since it shares the S58 with its larger siblings. One well-developed system therefore serves the whole family, which makes it widely proven rather than a niche part made for a single model.
Cool Air Where It Counts
Keeping the charge cool is central to the design. A G80 M3 cold air intake of this kind shields its filters from engine heat and feeds them with cooler air, so the gains are real rather than lost to a heat-soaked bay. It is the difference between an intake that only sounds good and one that genuinely helps the engine work.
Covered Across the Range
Because the S58 spans several M cars, one system fits a broad family. A G82 intake suits the M4 just as the same design serves the M2 and M3. The coverage sets out plainly:
- M2: chassis G87
- M3 saloon and touring: chassis G80 and G81
- M4 coupe and convertible: chassis G82 and G83
A Clean Fit
Fitting is straightforward for such a transformative upgrade. A G80 M3 air intake of this kind drops in where the factory box sat, clamping up with ordinary hand tools and nothing to cut or fabricate. Confirm your exact model and year before ordering, and as with any open intake the gains are modest on a standard car and come fully into their own once a supporting tune is in place.
