R2P Reinforced Intake Manifold B46/B48 (High Performance) – Flow Optimization for BMW and MINI

The R2P intake manifold is designed to replace the factory piece on BMW B46 and B48 engines, eliminating the flow restrictions that limit performance in high-level builds. Unlike stock manifolds, manufactured with cost and emissions compliance priorities, this unit prioritizes uniform air distribution between cylinders and resistance to high pressures, resulting in real gains in power and torque, especially in Stage 2 or higher setups.

Features

• Optimized airflow: Higher volumetric efficiency that directly increases available power across the entire rev range.
• Thermal and pressure resistance: Tested under extreme conditions, supports high-pressure turbo kits and methanol injection systems without deforming.
• Reinforced material: High-durability composite designed to withstand intense thermal cycles without performance loss.
• Methanol-ready: Compatible with water/methanol injection, essential in builds aiming to control intake air temperature.

Technical specifications

• Fuel compatibility: Gasoline and methanol injection.
• Testing environment: Optimized on dyno and real track conditions.
• Recommended use: Required for Stage 2 or higher builds with increased turbo boost pressure.

Why choose R2P over the factory manifold

Factory manifolds are limited by mass production processes and materials that prioritize cost over performance. The R2P manifold eliminates internal turbulence and redistributes flow more efficiently, allowing the engine to breathe better at high rpm. This is critical when running hybrid turbos, advanced engine management software, or methanol injection systems.

FAQ

• Is ECU remapping necessary after installation? Yes, a Stage 2 or higher remap is recommended to adjust air and fuel maps to the new flow characteristics.
• Can I use it with my stock turbo? Yes, but its benefits are most evident in builds that increase boost pressure.
• Does it include methanol injection ports? Yes, it's prepared to integrate safely with water/methanol injection systems.
