BMW N54 Charge Pipe/Chargepipe Kit by MMR | High-Flow Aluminium | 135i, 335i, 1M | E82 E88 E90 E91 E92 E93 (2006-2012) | CNC Ends, 1/8 NPT Meth Bung, Black

MMR Alloy Boost Pipe Upgrade for BMW N54 — 135i, 335i, 1M — E82 E88 E90 E91 E92 E93

Replace the fragile factory plastic turbo pipework on your N54 with this MMR alloy boost tube upgrade and enjoy rock‑solid boost control, quicker throttle pick‑up and long‑term reliability. Designed specifically for the BMW 135i, 335i and 1M on the E8x and E9x platforms, this hard pipe kit is the ideal foundation for remaps, bigger intercoolers and spirited road or track use.

The original plastic pressure pipe is notorious for cracking or blowing off under load, which leads to leaks and limp mode. MMR solves this with a smooth‑bore aluminium pipe, CNC‑machined ends for a secure seal, and a pre‑tapped 1/8 NPT port ready for water or methanol injection. Finished in a tough wrinkle black coating with a discreet logo, it looks OE‑plus in any bay.

Reasons enthusiasts choose MMR for the N54

• Alloy boost tube flows better than the brittle factory plastic pipework
• Holds higher pressure without popping off, ideal for tuned cars
• Smooth internal bore for sharper response and consistent boost delivery
• CNC‑machined connections for a tight, leak‑free fit to the throttle body
• Direct swap for BMW 135i, 335i and 1M with the N54 twin‑turbo engine
• Durable wrinkle black finish with subtle branding
• 1/8 NPT port included for easy methanol or water injection integration

We run this exact MMR setup on our own N54 builds, and our customers report faultless performance, better drivability and zero drama under hard acceleration. If you are planning a remap, FMIC upgrade or hybrid turbos, this boost pipe is essential.
