In the pursuit of being everything to everyone at a price that won’t break the bank, the x30i's have somewhat lost their spark. The stock 230i/330i/430i models come equipped with a rather bland air box that feels a bit unfinished, featuring a basic panel filter and an intake resonator designed to mute those turbo noises that performance enthusiasts actually love. Essentially, BMW has given x30i owners an air box that looks uninspiring, flows well enough but not optimally, and keeps the sound to a minimum. Enter the Dinan PEX intake, which addresses these shortcomings by providing a semi-open intake that flows an impressive 58% more air than the stock setup. This improvement leads to better throttle response and removes a potential hurdle for those looking to upgrade to a high-powered build (think upgraded turbo, fueling, etc.). Plus, it maintains a sleek OEM-like appearance that fits right in with the factory components under the hood, all while enhancing the sound with the removal of the intake resonator.

To achieve the standout flow that sets the Dinan intake apart, the entire lower box of the system has been redesigned and enlarged, making full use of the available space in the engine bay. This clever design allows for a 40% larger, custom, free-flowing filter, maximizing airflow. Dinan also aimed for a secondary inlet to effectively fill the volume of the enlarged air box and increased filter surface area. After numerous experiments with different shapes and sizes, they found that the patterned openings in the final design, located opposite the engine, provided the perfect balance. This setup helps the factory snorkel while keeping turbo inlet temperatures in check, regardless of testing conditions like gear pulls or speed runs.

While the extra airflow doesn’t translate to a significant power boost for stock or lightly modified vehicles, the Dinan intake system does open the door for those aiming to enhance their platform's power potential. In simple terms, if you're looking to build a more robust setup with turbo and fueling upgrades, this intake will help you get the most out of your efforts without being a limiting factor. Regardless of your build level, the secondary air inlets make the intake system more audible, allowing you to truly appreciate the turbo spool and BOV sounds—a refreshing change from Dinan's traditional fully sealed systems where induction noise is less noticeable. While the focus is on improved flow and sound, the understated PEX construction blends seamlessly into the factory engine bay, offering a visually appealing yet subtle upgrade.
