DINAN – Cold Air Intake – Toyota GR Supra 3.0 / BMW Z4 M40i (20 – 24)

To achieve these gains, Dinan re-engineered both the lid and the lower airbox, maximizing available engine-bay space to house a 40 % larger, free-flowing filter. The enlarged airbox is complemented by a secondary patterned inlet that balances volume and temperature for optimal flow without heat-soak penalties—confirmed through extensive testing across varied driving conditions.

The result is an intake system that delivers +13 WHP / +14 lb-ft of torque on an otherwise stock car and supports significantly higher power levels in tuned builds. Crafted entirely from 2×2 gloss-twill carbon fibre, it adds an unmistakable motorsport aesthetic that transforms the engine bay when paired with Dinan’s matching strut braces and carbon engine cover.
