Overview

The Dinan D760-0069 is a PEX cold air intake for the six-cylinder G-chassis M Performance cars: the M240i, M340i, and M440i with the B58 3.0-liter turbo engine. It replaces the factory air box with a semi-open housing molded from high heat-resistant PEX. You get most of the benefits of Dinan's carbon fiber intakes at a lower price, and the matte black finish blends in with the factory engine bay.

The housing is about 60 percent larger than stock. Inside is a conical high-flow filter with roughly 40 percent more filter area than the factory element. Slotted openings on the outboard side act as a secondary inlet that draws fresh air alongside the factory snorkel, not hot engine-bay air, so intake temperatures stay in check. Dinan measured up to 58 percent more airflow than the factory system, with peak gains of 9 wheel horsepower at 6,500 rpm and 8 lb-ft at 6,000 rpm on an otherwise stock car. Gains are larger on tuned cars that need more air.

Without the factory intake resonator, turbo spool and blow-off sounds are much more noticeable at part throttle and under boost. The kit includes the housing and lid, filter, inlet elbow, coupler, clamps, and small hardware. It fits cars with or without the factory strut brace and Dinan rates the install at about an hour. Dinan installation instructions (PDF).

This intake has no CARB Executive Order and is not legal for sale or use in California (Dinan emission code 7). It fits the U.S. B58 models in the table. It does not fit the four-cylinder 230i, 330i, or 430i, which use Dinan D760-0059 or D760-0070. It earns 3 Dinan points and ships in a 21.6 x 17.8 x 13.8 inch box weighing 10.1 pounds.
