MMR Aluminium Charge Pipe / Boost Pipe Kit for BMW 335i N55 E90/E92/E93 (2011-2013) - E9x 3 Series Intercooler/Pressure Pipe Upgrade, Direct-Fit Turbo Outlet & Throttle Body Tube with 1/8in Meth/Water Injection Ports

Give your E9x 335i the strong, reliable boost pipework it deserves. This MMR alloy charge tube replaces the fragile factory plastic piping on the 2011-2013 BMW 3 Series 335i N55, delivering rock-solid boost control, cleaner airflow and sharper pedal response on both standard and tuned cars. If you have experienced split plastic pipes or intermittent boost leaks, this is the dependable, direct-fit solution that enthusiasts trust.

Why it belongs on your N55

The stock pressure pipe is known to crack under higher load. MMR’s lightweight aluminium hard pipe uses smooth internal geometry to aid flow, resists deformation under vacuum or boost, and keeps charge pressure consistent for repeatable performance run after run. The crinkle black finish with subtle laser-etched branding looks OE-plus in the bay while standing up to heat and oil vapour.

Highlights

• Smoother bore alloy tubework for improved charge air velocity compared with the factory plastic part
• Stays intact at elevated boost levels - ideal for remapped cars and spirited road use
• Precision CNC-machined end for a secure, leak-free connection to OE fittings
• Two integrated 1/8 inch ports for water-methanol injection hardware if required
• Consistent boost, crisper throttle feel and more linear power delivery
• Durable crinkle black coating with laser-etched MMR detail
• Straight swap install using original-style couplers and retaining clip
