Dinan Cold Air Intake - 2019-2024 BMW 330i/430i

While the additional flow does not translate to any noteworthy rise in power output for stock or basic bolt-on equipped vehicles, the Dinan intake system does expand the potential of the platforms power ceiling. Put simply, those striving to build a more potent and robust solution, complete with turbo and fueling upgrades, will be allowed to maximize the results without worry of the intake system being a limiting factor. Regardless of the level of build, the secondary air inlets 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 increased flow 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.
