Introducing the do88 Intake System for BMW 320i and 330i G20 – Engineered for Maximum Performance!

At do88, we understand that filtration, airflow, and heat management are crucial when designing an intake system for turbocharged engines.

Our intake system is designed to provide the turbo with excellent filtration, an optimized airflow path, and consistently low inlet temperatures. One of the key challenges with the B48/B46 engine is the intake system’s location near the exhaust manifold, which generates intense heat and causes rapid heat soak.

High intake air temperatures (IATs) can significantly reduce engine performance, as hot, less dense air makes it harder for the turbo to build boost efficiently. To address this, our fully sealed intake system minimizes heat exposure and maintains low IATs. However, fully sealed systems can face airflow restrictions due to the factory airbox’s single air feed. We resolved this by adding a secondary air feed and incorporating a heat shield into the airbox design to block heat from the exhaust manifold. The large 7” airbox ensures ample airflow around the filter and accommodates strut braces.

We replaced the stock intake hose with a high-flow 102mm (4”) mandrel-bent aluminum pipe paired with a custom silicone hose. The system also features a custom-designed air filter with tightly woven cotton gauze for exceptional filtration. The filter is washable, reusable, and built for long-lasting performance.

Unlike the stock air filter box and intake hose, which are designed with silencers to reduce turbo and induction noise, the do88 system eliminates these elements. This allows for a more pronounced and engaging turbo spool and induction sound, giving you a truly dynamic driving experience.

With CNC machined serviceable/cleanable nozzle inserts for precise fluid metering. Choose single or dual nozzles and match the flow rate to your power needs! ​Water/Methanol Injection (WMI) nozzles are determined by the intended power and how many bungs your charge pipe has. These nozzles are 1/8” NPT and screw in to bungs included on most aftermarket charge pipes. BMS "super atomizing" nozzles are designed and manufactured by BMS and are known for their great atomization and flow characteristics. The number on the methanol injection nozzle represents the approximate gallons per hour of fluid when at full flow. Generally speaking running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution.
