Silicone Intake Kit for BMW S63B44T4 4.4T V8 Twin‑Turbo F90 M5, F91/F92/F93 M8 (2018‑2023). Direct bolt‑on replacement for bulky OEM plastic intake resonator assembly. Heavy‑duty multi‑ply reinforced silicone hoses are custom routed for large V8 engine bay. Dual open‑element high‑flow cone filters draw cool ambient air, cut intake restriction, sharpen turbo response and reduce IAT heat soak under heavy load. Unlock full V8 performance and deliver deep signature twin‑turbo induction sound. No cutting or modification required, all mounting hardware supplied.

Fit Engine: S63B44T4 4.4T V8 Twin‑Turbo
Fit Chassis: F90 M5 / M5 Comp; F91 M8 Convertible, F92 M8 Coupe, F93 M8 Gran Coupe, Year 2018‑2023

Multi‑ply reinforced silicone engineered for extreme V8 under‑hood heat. Resist high temperature and boost vacuum, prevent hose collapse. Superior durability versus brittle OEM plastic tubes, ideal for track heavy‑load usage.
Eliminate restrictive stock resonator box. Optimized tubing inner diameter + dual high‑flow filters deliver sufficient airflow for twin turbos. Reduce turbo lag and improve mid‑range power delivery.
Cold‑air intake design lowers intake air temperature. Minimize power heat‑soak during continuous aggressive driving on track or mountain roads, stabilize big‑V8 power output.
Custom‑made hose routing for F90 M5 / M8 chassis. Hoses clear radiator, turbo housing and wiring harness, zero‑interference fitment without force‑bending tubes.
Deep, layered V8 turbo induction sound. Enhanced intake noise without harsh high‑pitch whistling, great for daily driving and performance applications.
Compatible with stock factory ECU. Also supports Stage1 / Stage2 & higher‑level turbo upgrade tuning, leaves airflow margin for future power modification. Pure bolt‑on fitment, no permanent changes to OEM parts.
