Description
The Dinan intake system outflows the factory setup by over 12% at 28" of H2O and averages 14% greater flow across all the tested scenarios. This translates into the ability to support higher power levels (ie: future-proofing the intake as a restriction to your future goals). The chart shown below is the summation of individual CFM measurements for both OEM driver and passenger intake tracts and in the case of the Dinan flow measurements, both boxes joined with the shared plenum. Utilizing a central plenum as opposed to two separate intake paths created a challenge in comparing the flow measurements of stock vs. Dinan on the bench but one that needed to be done to ensure the viability of the preferred symmetrical design. Numerous test sets to challenge and/or verify the data were used which included the following setups:
1 turbo inlet blocked with both filter sides open.
1 turbo inlet blocked with one filter inlet blocked.
1 turbo inlet blocked with the plenum blocked 2" past the opposite turbo inlet to as closely simulate the OEM individual pathways as possible.
With each successive test it became apparent that no matter the combination, the CFM measurement itself was largely unaffected by the shared plenum regardless of how much extra volume on the opposing side of the path was being utilized. In fact, between all 3 setups, the difference in CFM was within 2% across the entire range. Additional tables breaking down the individual driver and passenger banks are also supplied for those looking for more minute detail.
Discover the unrivaled power and stunning beauty of the DINAN Gloss Carbon Fiber Cold Air Intake designed specifically for the 2021-2023 BMW M3/M4 and 2023+ M2 Comp models. With its groundbreaking S58 inline-6 engine, the latest generation of the M3 has redefined performance boundaries. Now, DINAN takes it to the next level with an option for AWD and a meticulously engineered carbon fiber cold air intake system.
Designed to deliver optimal function, captivating sound, and breathtaking aesthetics, the DINAN G8x Carbon Fiber Cold Air Intake is more than just a visual upgrade. Experience a remarkable 12% increase in airflow to your engine, without compromising inlet temperatures or pressure. This means your Dinan-modified BMW can achieve greater power potential on modified builds, thanks to the increased efficiency of the turbos. By drawing in more unimpeded air, the Dinan G8x system ensures the same power can be achieved with less effort, resulting in enhanced performance.
At the heart of this design is a singular plenum that replaces the separate driver and passenger intake ducting found in the stock setup, creating a symmetrical engine bay that is both visually appealing and functional. This innovative configuration allows for a 50% increase in volume within the limited space, while also simplifying the installation process. Furthermore, the enlarged airboxes with 11% larger cotton air filters offer superior filtration and maximize airflow. Additional cutouts on the top of each airbox lid, coupled with the factory grill inlets, ensure optimal flow without compromising temperature control. Moreover, these secondary airbox passages provide an avenue for the induction soundtrack to be unleashed, offering an exhilarating auditory experience during acceleration, deceleration, and spooling.
The DINAN G8x M3/M4 intake system not only improves flow and sound, but it also boasts an unmatched appearance. Meticulously designed to seamlessly blend with the factory engine bay, the DINAN intake enhances the overall aesthetic to a tier above. With its use of a 2x2 twill carbon fiber weave, available in either gloss or matte finish, this intake system exemplifies DINAN's commitment to OEM+ quality and style.
Features:
- Reduced intake restriction for increased turbo efficiency and greater power potential on modified builds.
- More robust and aggressive induction soundtrack.
- Improved throttle response.
- Enhanced airflow with a 12.4% increase over the stock system (Stock: 815 CFM, Dinan: 916 CFM @ 28" H2O).
- Larger volume airboxes (26% larger than stock) and tubes/plenum (50% larger than stock) to maximizethe volume of air utilized.
- 11% increase in filter area (stock: 65in², Dinan: 72in² per side) for optimum flow.
- Multiple finish options: Available in 2x2 Gloss or Matte Twill Carbon (Gloss Twill shown).
- Bolt-on installation for ease of use.
