**FOR CAR THAT HAS A BRACE**
The M340i is an impressive car in terms of performance and style, but its stock intake system fails to convey its true capabilities. The dry and lifeless air box, accompanied by a basic panel filter and an intake resonator designed to eliminate turbo/intake noises, does little justice to the power and excitement that the M340i platform offers. BMW missed the mark by providing M340i owners with an uninspiring air box that hampers airflow, emits no noise, and fails to match the platform's sporty character.
Fortunately, Dinan has developed the perfect solution with their carbon fiber intake system for the M240i, M340i, and M440i models. This upgrade rights the wrongs of the stock system by delivering a semi-open intake design capable of flowing 58% more air compared to the stock system. The result is increased top-end power and improved throttle response, transforming the driving experience. Furthermore, the Dinan intake enhances the vehicle's appearance with its aggressive and sporty carbon fiber construction, while also providing a noticeable increase in engine sound by removing the intake resonator and implementing a semi-open design.
To achieve these impressive flow gains, Dinan has reworked and enlarged the entire lower box of the intake system, maximizing the available space in the engine bay. This allows for the inclusion of a 40% larger, custom, free-flowing filter that optimizes airflow and ensures maximum performance. Additionally, Dinan desired a secondary inlet to effectively fill the volume of the enlarged air box and increased filter surface area. Through extensive experimentation, Dinan determined that patterned openings located on the opposite side of the engine provide the perfect balance of additional volume without increasing turbo inlet temperatures. This design consideration ensures optimal performance under various testing conditions.
With the Dinan Cold Air Intake, the increased airflow translates into improved throttle response and noticeable power gains, delivering a maximum increase of 9 horsepower and 8 foot-pounds of torque at 6500 RPM, even on a completely stock vehicle. The addition of secondary air inlets also enhances the intake system's sound, allowing you to appreciate the turbo spool and blow-off valve. This is a departure from Dinan's traditional fully sealed systems, where induction noise is less prominent. Not only does the Dinan intake enhance performance and sound, but it also enhances the visual appeal under the hood with its immaculate carbon fiber construction. It's a worthwhile addition to an already impressive vehicle.
Key Features:
- More Power: Experience maximum gains of 9 horsepower and 8 foot-pounds of torque at 6500 RPM on a completely stock vehicle.
- Enjoyably Louder, Sportier Sound: Hear the turbo spool and blow-off valve with an enhanced engine sound.
- Improved Throttle Response: Feel the difference with better throttle response for a more engaging driving experience.
- Outflows Factory Intake: The Dinan Cold Air Intake outperforms the stock closed box design by at least 58% in terms of airflow restriction. By allowing the engine to breathe more freely, this intake system lowers the intake air temperature, optimizing performance gains. Even on a completely stock vehicle, you can expect improvements of up to 9 horsepower.
- Larger Volume Air Box: The Dinan intake system features a 60% larger air box compared to the stock system, providing ample space for increased airflow and improved performance. The larger volume allows for better air distribution and ensures optimal flow dynamics.
- Increased Filter Area: With a 40% increase in filter area, the Dinan Cold Air Intake maximizes airflow efficiency. The stock intake offers 82 square inches of filter area, while the Dinan intake provides a substantial 115 square inches. This larger filter area promotes better filtration and airflow, resulting in enhanced engine performance.
- Quick and Easy Installation: The Dinan Cold Air Intake is designed for straightforward installation, allowing you to enjoy the benefits of improved performance in no time. With detailed instructions and all necessary hardware included, the installation process is hassle-free.
Flow Bench Testing:
The Dinan Intake System has undergone rigorous flow bench testing to ensure its superior performance. The results demonstrate a significant improvement over the factory intake, surpassing its restrictive design. By optimizing airflow and reducing restrictions, the Dinan intake system unleashes the true potential of your BMW, providing noticeable gains in both power and torque.
Note: For vehicles with a brace, the version with a brace will fit both cars with and without a brace. However, the version without a brace will not fit cars equipped with a brace. Please ensure the correct version for your specific vehicle.
Upgrade your BMW M240i, M340i, or M440i with the Dinan Cold Air Intake, and experience a remarkable improvement in performance, sound, and aesthetics. Unlock the true potential of your vehicle and enjoy a more exhilarating driving experience with Dinan's expertise in intake system engineering.
