BMW often uses plastic for OEM charge pipes. While cost-effective, these pipes are not ideal for pressurized air. With aging or increased boost, plastic pipes are prone to failure. A failing pipe can cause reduced power (limp mode) or prevent the car from starting, potentially leaving you stranded.
Most aftermarket B48 charge pipe kits use a basic design: two pipes joined by a straight reducing silicone hose. These do not account for thermal movement, which often causes hoses to pop off. Over-tightening clamps usually damages the pipes.
At do88, we took a different approach. The system features a flexible aramid-reinforced silicone hose with 3 humps, allowing movement in any direction without stressing connections. Pipes have CNC-machined 6063 hose ends with 3mm wall thickness, preventing deformation even under overtightened clamps.
The do88 pipes also improve performance. The lower pipe measures 60mm (2 3/8”;) and the upper pipe 76mm (3”;) with smooth mandrel bends to reduce pressure drop and turbulence. The upper pipe connects to the throttle body via a CNC-machined flange and has two 1/8 NPT ports for methanol injection or boost pressure sensors. Two 1/8 NPT plugs are included for unused ports.
Kit Features:
- Flexible hose connection between upper and lower pipes prevents the hose from popping off.
- 3-humped silicone hose reinforced with high-temperature aramid fabric and stainless-steel rings.
- High-quality Mikalor hose clamps with inner rings to protect the hose and evenly distribute clamp pressure.
- Improved airflow and reduced backpressure.
- 12% more flow than OEM: 558 CFM @ 150 mbar (2.17 psi) vs OEM 500 CFM.
- CNC-machined hose connections matching pipe inner diameter for safe clamping.
- CNC-machined MAP sensor boss, turbo, and throttle body connections.
- CNC-machined (2x) 1/8 NPT ports for methanol injection or boost pressure sensors.
- Two 1/8 NPT plugs included for unused ports.
- Mandrel-bent 60mm (2 3/8”;) and 76mm (3”;) charge pipes with black powder coat finish.
- No interference with the engine cover.
- Complete hardware and instructions included for installation.
