Dinan 17-20 BMW 430i Cold Air Intake

Beyond the additional sound opening the semi-open intake takes the same path to success as its closed box counterpart. Improve upon the factory design by increasing flow via a larger airbox and filter element thereby improving throttle response and lessening the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign are a major factor in ultimately producing a more potent intake, they are not the only variables in creating a more efficient design either. The devil is in the details which is where Dinan thrives. Dinan engineers focused their attention on the intake pipe itself where numerous improvements could be made. In factory configuration, the intake tube comes complete with baffling and a small Helmholtz chamber to reduce unwanted sound. As a byproduct, these features also cause a more turbulent airflow path which robs the factory system of potential power. These two specific details are diametrically opposed to our intended market's desires, so the removal of these features was paramount. Through numerous iterations, a carbon fiber intake tube was developed that eliminated flow disruptions and allowed the natural sound of an unimpeded intake tract to sing. All told this thorough methodology of design allows the Dinan carbon fiber intake for the B46/B48 engine to elicit gains of 6 HP and 6 TRQ at 5000 RPM on a completely stock vehicle. Semi-Open - Carbon Fiber - F22/F23/F30/F31/F32/F33/F34/F36 For those who own a closed box Dinan intake (D760-0048) but now want to switch to the semi-open intake without purchasing a completely new kit, you can order the retrofit kit, SKU D763-0213-G-A (lid only), separately.

• 50 State Emissions Legal (partial application list): CARB EO D-176-56 (2019-21 F2x/F3x 230i/330i/430i Only)
• More Power: + 6 HP @ 5000 RPM & + 6 lb-ft @ 5000 RPM (+ 5 WHP & + 5 WTQ) without additional modifications
• 34% increase in filter area (stock: 76.3in², Dinan: 102.1in²) for optimum flow
• Free flowing injection molded Air Mass Meter housing (ove 20% larger then stock)
• Larger volume air box (30% larger than stock) for increased breathability
• A pronounced sporty sound courtesy of a semi-open design
• Optimized carbon fiber intake tube
• Quick and easy installation
• Improved throttle response

Upgrade the factory intake system with the Dinan D760-0048-A semi-open carbon fiber cold air intake, engineered for BMW models equipped with the B46 or B48 engine. This performance intake improves airflow, throttle response, and intake sound while helping reduce the strain placed on the turbocharger. Its semi-open design delivers a pronounced sporty induction sound without sacrificing the efficient airflow characteristics of a properly engineered airbox and filter system.
Dinan increased the airbox volume and filter area to support improved breathability compared with the factory configuration. The injection-molded air mass meter housing is over 20% larger than stock, while the airbox provides approximately 30% more volume. The filter area is increased by 34%, helping the system maintain strong airflow under demanding driving conditions. On a completely stock vehicle, the Dinan intake is engineered to produce gains of up to 6 horsepower and 6 lb-ft of torque at 5,000 RPM, with no additional modifications required.
The optimized carbon fiber intake tube removes factory baffling and the Helmholtz chamber, which can disrupt airflow and suppress natural intake sound. Through extensive development, Dinan created a smoother intake path that supports more efficient airflow and allows the engine’s induction note to be heard. Installation is designed to be quick and straightforward using the factory mounting locations and connections. The intake fits select BMW 2 Series, 3 Series, and 4 Series models, including the F22, F23, F30, F31, F32, F33, F34, and F36 chassis.
This Dinan D760-0048-A intake is semi-open and intended for applications listed in the vehicle fitment information. Owners of the Dinan closed-box D760-0048 intake can convert to the semi-open configuration by purchasing the D763-0213-G-A lid separately. Emissions certification applies only to specific applications; verify the applicable vehicle and approval requirements before installation.
