do88 Charge Pipe BMW G-Series (B58)
The do88 charge pipe for BMW G-Series models equipped with the B58 engine is an essential upgrade for improving durability and performance. The B58 Gen 2 engine is renowned for its power, but it has a weak point—the factory charge pipe, which can crack under stress, especially during spirited driving or track sessions. If you are planning to tune your vehicle, upgrading to this charge pipe is highly recommended.
Why Choose the do88 Charge Pipe?
Many aftermarket charge pipe solutions on the market do not adequately consider the system’s thermal dynamics, which can lead to performance issues. The do88 charge pipe addresses these concerns with innovative design features:
- Flexible Connection: The charge pipe includes a specially designed aramid reinforced silicone hose with a 3-hump design, allowing it to flex without compromising integrity. This prevents issues such as hoses popping off due to thermal expansion.
- CNC-Machined Ends: The hose connection ends are made from 6063 aluminium with a 3mm wall thickness, ensuring maximum durability that resists deformation even under excessive clamping.
- Improved Airflow: With larger diameter pipes and smooth mandrel bends, the do88 charge pipe enhances airflow, reducing pressure drop and turbulence. This increases efficiency and engine responsiveness.
Performance Benefits
The do88 charge pipe offers significant improvements over the stock option, including:
- 27% more airflow than the OEM part, with an impressive 558 CFM at 150mbar (2.17psi).
- CNC machined ports for methanol injection or boost pressure sensors, along with plugs for those not using these features.
- Stylish black powder coat finish that does not interfere with the engine cover.
