do88 Intake System – BMW B58 (Gen 1 & Gen 2) & S58 G8X

OVERVIEW

The factory airbox and intake tract on the B58 and S58 engines is adequate at stock power levels but becomes a real restriction once boost increases. do88's Intake System is a complete replacement for the factory intake — engineered from scratch for each specific platform rather than a generic universal kit — designed to maximize airflow to the turbo(s) while keeping intake air temperatures down. This listing covers all three do88 intake variants: B58 Gen 1 (F-Series), B58 Gen 2 (M240i/M340i G-Series), and S58 (G8X twin-turbo).

SPECS

• Design approach: Designed from scratch for each specific platform, using the factory airbox as a template and test-fitted on the actual vehicle for accurate fitment — not a universal cone filter adaptation
• Filtration: High-flow, reusable air filter(s) engineered for the specific intake tract (S58 uses two filters for its twin-turbo layout); do88 also sells replacement filters separately for ongoing maintenance
• Piping: Mandrel-bent aluminum piping sized for the turbo inlet(s) on each platform
• Construction: Designed for durability and consistent performance under sustained track use, not just a peak-dyno-number product

PARTS INCLUDED

• 1x do88 intake system for the selected platform: piping, air filter(s), and mounting hardware

TECH RESOURCES

• Complete, direct replacement for the factory intake/airbox using factory mounting points — no permanent modification required.
• do88 provides installation instructions with each kit.
• Pairs well with a do88 charge pipe kit and/or charge cooler manifold for a complete intake/charge-air system upgrade, though it installs and functions independently.
• Replacement air filters are available separately for ongoing maintenance without needing to replace the full intake system.
