BMW F32/F33/F36 4 Series 440i Gold Titanium Metal Charge Pipe Upgrade Kit – Fortified Reliability, High-Strength Metal, Improved Throttle Response & Heat Resistance | Fits 2016–2019 (SWB / LWB, RWD / xDrive, EU / Asia / US Models) with B58 Gen 1 Engine

Upgrade both the performance and aesthetics of your 4 Series with the BAVMODS® Gold Titanium Metal Charge Pipe Upgrade Kit, precision-engineered for BMW F32, F33, and F36 models equipped with the B58 Gen 1 engine.

The factory plastic charge pipe is one of the most failure-prone components on the B58 platform — known to crack, split, or blow apart under high boost or heat stress. This reinforced titanium-coated aluminum replacement eliminates that weakness entirely, delivering both long-term reliability and a premium, high-spec visual upgrade that makes your engine bay stand out.

Each pipe features a brilliant gold titanium finish that reflects heat and brings a striking motorsport aesthetic to your 440i’s bay. The precision-machined interior ensures ultra-smooth airflow and reduced turbulence, resulting in sharper throttle response, quicker turbo spool, and stable boost pressure through every gear.

Designed for both stock and tuned applications, this upgrade combines functional engineering with visual excellence — it’s as beautiful as it is bulletproof.

Performance You Can Feel

The BAVMODS® Gold Titanium Charge Pipe isn’t just about looks — it’s about delivering real, tangible performance gains. Expect crisper throttle engagement, improved boost retention, and smoother power delivery across the entire rev range.

Its rigid construction prevents flex or expansion, while the titanium finish helps dissipate heat, keeping intake temps lower and performance consistent. When you lift the hood, the golden hue immediately elevates your engine bay — the perfect blend of form and function, built for enthusiasts who demand excellence.

Why It Matters

The charge pipe serves as the vital link between your turbo and intercooler — and the factory plastic version is a known failure point, especially in tuned or aggressively driven cars. A cracked pipe can lead to sudden boost loss, poor drivability, and limp mode.

The BAVMODS® Gold Titanium Metal Charge Pipe Upgrade Kit eliminates this risk while improving performance, durability, and style. It’s the perfect way to reinforce your 4 Series’ turbo system while giving your engine bay the aesthetic quality it deserves.

Strong. Functional. Beautiful. Built to perform — and designed to impress.
