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

The R2P intake manifold is designed to replace the original part on BMW B46 and B48 engines, eliminating the flow restrictions that limit performance in high-level builds. Unlike stock manifolds, manufactured with cost and homologation criteria in mind, this unit prioritizes uniform air distribution between cylinders and resistance to high pressures, which translates into real gains in power and torque, especially in Stage 2 or higher configurations.

Key features

• Optimized airflow: Greater volumetric efficiency that directly increases the available power across the entire RPM range.
• Thermal and pressure resistance: Tested under extreme conditions, it withstands high-pressure turbo kits and methanol injection systems without warping.
• 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 temperature.

Technical specifications

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

Why choose R2P over the original 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 revs. This is critical when installing hybrid turbos, advanced management software, or methanol injection systems.

Frequently asked questions

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