Description
Unlock your BMW’s full potential with the Forge Motorsport Induction Kit designed specifically for BMW models equipped with B46 and B48 engines. This precision-engineered kit enhances airflow efficiency, power output, and throttle response while delivering a refined induction sound that enthusiasts crave.
Step 1 – Enhanced Air Intake Duct:
UK and some EU-spec F chassis BMWs feature a factory blank designed to prevent the low-pressure zone in front of the radiator from feeding air into the inlet tract. Forge Motorsport replaces this restrictive blank with the FMINLD2, a meticulously sculpted carbon fiber duct that channels a greater volume of fresh air directly into the airbox, improving overall intake efficiency.
Step 2 – High-Flow Performance Filtration:
To capitalize on the increased airflow, Forge Motorsport integrates a high-flow, cone-style performance filter. This filter, developed from extensive testing and refinement of previous upper airbox induction kits, maximizes filtration surface area without compromising airflow, ensuring your engine breathes clean, unrestricted air.
Step 3 – Optimized Inlet Hose Design:
The original equipment manufacturer (OEM) inlet hose is a notable bottleneck due to its sound resonator and accordion-style ribs that cause turbulence, reducing airflow velocity. Forge Motorsport addresses this by replacing the OEM hose with a custom-built, multi-ply smooth silicone inlet hose. This hose not only reduces airflow turbulence significantly but is also engineered to withstand higher stresses and tuned engine mapping thanks to its robust 5-ply silicone construction.
Performance Gains:
-
Up to +8bhp increase across the entire rev range
-
Up to +7Nm torque gains throughout the rev range
-
Enhanced induction sound for a sportier driving experience
-
Included induction kit and inlet hose with full installation instructions
Material and Thermal Benefits:
Constructed from premium prepreg 2x2 twill carbon fiber, this kit combines exceptional strength, lightweight design, and stunning aesthetics. Carbon fiber’s inherent low thermal conductivity helps reduce heat soak, minimizing heat transfer to adjacent components. Lower Inlet Air Temperatures (IATs) translate to denser air entering the combustion chamber, optimizing combustion efficiency, increasing engine power, and maintaining safe Air-Fuel Ratios (AFRs) for enhanced engine reliability.
Additional Features:
-
Increase in airbox inlet diameter from 85mm to 90mm for improved airflow
-
Multi-ply silicone hose enhances durability and longevity compared to OEM parts
-
Lifetime warranty backed by Forge Motorsport’s commitment to quality and performance
Vehicle Compatibility:
Compatible with a wide range of BMW models fitted with 2.0L B46/B48 engines from 2013 through 2024, including various trims of 230i, 320i, 330i, 420i, and 430i models, both rear-wheel and xDrive configurations.
