Description
Looking for more performance for less cost? The Dinan PEX Cold Air Intake for 2020-2024 BMW M240i, M340i, and M440i delivers exceptional performance and sound benefits at an unbeatable price point. This intake system offers a substantial improvement in airflow and throttle response while blending seamlessly with the OEM engine bay aesthetics.
BMW's stock intake system on the Mx40i models is practical but uninspiring, featuring a basic airbox and panel filter designed to muffle intake noise. The Dinan PEX intake transforms this setup, flowing 58% more air than the stock system and enhancing the engine's auditory presence by removing the intake resonator and implementing a semi-open design.
The Dinan intake system replaces the entire lower box, enlarging it to utilize the available engine bay space and accommodating a 40% larger custom filter. This design maximizes airflow, crucial for high-powered builds with upgraded turbo and fueling systems. The secondary inlet design, carefully tested for optimal performance, ensures no increase in air temperatures, maintaining efficiency even under demanding conditions.
With more air being pulled into the system, throttle response is improved, and additional power is realized in the form of max gains of +9 WHP / +8 lb-ft of torque. The secondary air inlets also allow the intake system to be more audible so the turbo spool and BOV can be appreciated. A stark difference from Dinan's traditional fully sealed systems where induction noise is not nearly as recognizable. While power and sound are the stars, the modest PEX construction fuses effortlessly into the factory engine bay for a reserved visual that despite basic materials still manages to draw attention. It's an economical solution to form and function for a vehicle that permeates both.
