BMW E9X 335i/335is TIG-Welded Aluminum Intake Manifold with Integrated Metal Fuel Rail – Enhanced Airflow, Boost Stability & Long-Term Reliability | Fits 2007–2013 (N54 Engine)

Unlock consistent airflow and boost stability with the BAVMODS® TIG-Welded Aluminum Intake Manifold, engineered specifically for the BMW E9X 335i/335is. Designed as a direct replacement for the restrictive factory plastic manifold, this upgrade is ideal for tuned and boosted setups running higher-than-stock boost levels.

Constructed from high-strength, TIG-welded aluminum, this manifold withstands the pressure, heat, and vibration that often cause OEM plastic manifolds to fail under performance conditions. The included CNC-machined aluminum fuel rail ensures steady fuel delivery — a must for ethanol blends (E85), upgraded injectors, or high-performance tunes.

Whether your goal is long-term reliability or smoother power delivery, this upgraded metal manifold improves airflow distribution, throttle response, and mid-to-top-end consistency, helping your N54 engine breathe more efficiently under load.

Proven Performance Benefits

• Improved Airflow Distribution – Optimized internal runner design provides smoother, more balanced airflow to all cylinders, increasing overall engine efficiency.
• Boost Pressure Stability – Reduces turbulence and pressure loss, allowing more consistent boost levels and stronger power delivery throughout the rev range.
• Enhanced Throttle Response – Air reaches the combustion chambers faster, sharpening response during acceleration and gear changes.
• Increased Reliability Under Boost – TIG-welded aluminum construction resists cracking, heat fatigue, and boost leaks common with OEM plastic manifolds.
• Upgraded Fuel System Capability – Integrated CNC-machined aluminum fuel rail supports high-flow injectors and ethanol setups for advanced tuning flexibility.
• Ideal for Tuned & Turbocharged Setups – Proven to support higher boost levels and additional fueling systems for performance builds.
