For BMW S58 (G8X M3/M4, G87 M2 and derivatives)
Give BMW’s S58 the lungs it deserves. The PRORAM PRK-276-BK replaces the restrictive factory airboxes with a dual-cone, open induction system that feeds your turbos cooler, denser air while unleashing the S58’s trademark spool, whoosh and flutter. The kit pairs high-flow pleated nanofibre filters with sculpted heatshields and real carbon-fibre lids, delivering a clean OEM+ look with measurable performance headroom.
Real gains you can feel – Free-flowing 90 mm intake tracts reduce pressure drop ahead of the turbos for crisper throttle response and stronger mid-range pull. Top tuners describe “excellent power gains” with this setup, matching what customers report after mapping or running higher boost. Some reaching well over 32BHP in gains.
Sound that suits the car – Expect a deeper intake growl under load and pronounced turbo induction noises; users describe it as having an “incredible intake sound.”
True performance media – PRORAM pleated dry nanofibre filters flow hard, filter fine, and clean easily, no oiling needed.
Engine-bay presence – Black powder-coated hardware and those carbon lids turn the S58 bay into a showpiece without looking aftermarket-loud. This kit has an amazing OE-plus aesthetic.

Dual PRORAM pleated dry filters
Left/right laser-cut black powder-coated heatshields with carbon-fibre lids

A competent DIYer can install the kit with basic tools; full hardware is included. Heatshields and lids use factory pick-up points, and the CNC adapters ensure clean turbo interfaces. Filters clean with standard PRORAM/Ramair maintenance kits—no re-oiling, no MAF residue.
Sharper tip-in and stronger mid-range surge vs. stock airboxes. Common responses from industry tuners mention about performance and throttle response.
More character: clearly audible spool and blow-off sounds under load that many buyers seek on the G8X/G87 platforms. Buyers and forum chatter consistently point to the sound improvement as a headline trait of this kit.
Airflow path: Enlarged dual 90 mm vs. narrower OE snorkels → lower pre-turbo restriction.
Filtration: Dry nanofibre (wash/reuse, oil-free) vs. paper element → high flow without oiling concerns.
Thermal: Carbon-topped heatshields help isolate from engine-bay heat compared with open cones alone.
