Dinan PEX Cold Air Intake - BMW B48 2019-2026

The Dinan PEX cold air intake replaces the restrictive factory airbox with a fully reworked, enlarged lower box and lid that use as much of the engine bay as possible, housing a custom free-flowing filter with 40% more area than stock (115 sq in vs 82 sq in). A patterned secondary inlet on the side opposite the engine adds volume to supplement the factory snorkel without raising turbo inlet temperatures across single or multi-gear pulls, constant speed, and 0 to 100 mph runs. The larger air box holds about 60% more volume than stock and outflows the factory intake by 58% or more, sharpening throttle response and adding a sportier induction sound. High heat deflection PEX construction keeps a clean OEM look.
