The M440i/M340i is an impressive car in terms of performance and style but that is not conveyed when viewing its lackluster stock intake system swaddled by seemingly unfinished strut braces. In stock trim, the M440i/M340i comes with a dry and lifeless airbox housing a basic panel filter that is also accompanied by an intake resonator whose job it is to eliminate turbo/intake noises. The same noises that those in the performance world relish. Essentially BMW has seen fit to give M440i/M340i owners an airbox that looks uninspiring, flows adequately but not ideally, and emits no noise. The exact opposite of what the platform exudes otherwise. The Dinan carbon fiber intake for the platform rights these wrongs and delivers a semi-open intake capable of flowing 58% more air than the stock system resulting in additional top-end power and increased throttle response. At the same time revealing a more aggressive, sporty carbon fiber appearance, and an increase in sound courtesy of the removal of the intake resonator and implementation of a semi-open design. In order to achieve the gains in flow that set the Dinan intake system apart, the entire lower box of the system, and not just the lid, has been reworked and enlarged in an effort to make use of as much of the available real estate as possible within the engine bay. In turn, this allows a 40% larger, custom, free-flowing filter to be housed within and maximum flow to be realized. However, a secondary inlet has always been desired by Dinan in order to effectively fill the volume of the enlarged airbox and increased filter surface area. This desire led to a multitude of experiments being conducted on the effectiveness of a possible open-air inlet in the system. With different shapes, locations, and sizes of openings being tested, the goal was to ensure that the added secondary inlet did not cause any unwarranted side effects such as an increase in air temps in the system. This is commonplace with open-air intake systems where overheated engine bay air is employed in the intake tract. The results of these tests showed that the patterned openings present in the final iteration of the box located on the opposite side from the engine provided a perfect balance of additional volume to assist the factory inlet all the while not causing an increase in turbo inlet temperatures. This was the case regardless of testing conditions (single/multiple gear pulls, constant speed, 0-100mph runs, etc.). With more air being pulled into the system, throttle response is improved and additional power is realized in the form of max gains of +9 WHP / +8 ft-lbs of torque. The secondary air inlets also allow the intake system to be more audible so the turbo spool and BOV can be appreciated. A stark difference from Dinan's traditional fully sealed systems where induction noise is not nearly as recognizable. Not to be outdone by the increased power and sound, the outwardly visible system is made of immaculate carbon fiber so the under the hood appeal is vastly improved over its drab and utilitarian beginnings. A worthy piece to add to an already impressive vehicle. Features: More Power: Max gains of 9 WHP and 8 lb-ft of torque @ 6500 RPM on a completely stock vehicle. Enjoyably louder, sportier sound. Improved throttle response Outflows factory intake by 58% or more. Larger volume airbox (60% larger than stock). 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow. Compatible with all G2X MX40i's with and without factory bracing. Quick and easy installation

Looking for more, for less? The all new G2x/G4x Mx40i PEX Intake delivers all the performance and sound benefits as its carbon fiber sibling -- just with less showmanship -- resulting in the best dollar-per-horsepower B58 intake system available from Dinan. The Mx40i's are an impressive lot in terms of performance and style but that is not conveyed when viewing its lackluster stock intake system swaddled by seemingly unfinished strut braces (where applicable). In stock trim, the Mx40i comes with a dry and lifeless air box housing a basic panel filter that is also accompanied by an intake resonator whose job it is to eliminate turbo/intake noises. The same noises that those in the performance world relish. Essentially BMW has seen fit to give Mx40i owners an air box that looks uninspiring, flows adequately but not ideally, and emits no noise. The exact opposite of what the platform exudes otherwise. The Dinan PEX intake for the platform corrects these wrongs and delivers a semi-open intake capable of flowing 58% more air than the stock system resulting in additional top end power and improved throttle response. At the same time revealing an enhanced OEM-like appearance that blends seamlessly with surrounding factory plastic under hood components, and an increase in sound courtesy of the removal of the intake resonator and implementation of a semi-open design. To achieve the gains in flow that set the Dinan intake system apart, the entire lower box of the system, and not just the lid, has been reworked and enlarged to make use of as much of the available real estate as possible within the engine bay. In turn, this allows a 40% larger, custom, free flowing filter to be housed within and maximum flow to be realized. However, a secondary inlet has always been desired by Dinan in order to effectively fill the volume of the enlarged air box and increased filter surface area.

The secondary air inlets also allow the intake system to be more audible so the turbo spool and BOV can be appreciated. A stark difference from Dinan's traditional fully sealed systems where induction noise is not nearly as recognizable. While power and sound are the stars, the modest PEX construction fuses effortlessly into the factory engine bay for a reserved visual that despite basic materials still manages to draw attention. It's an economical solution to form and function for a vehicle that permeates both. Features: More Power: Max gains of 9 WHP and 8 lb-ft of torque on a completely stock vehicle High heat deflection PEX construction and an OEM look Enjoyably louder, sportier sound Improved throttle response Outflows factory intake by 58% or more Larger volume air box (60% larger than stock) 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow Compatible with all G2x Mx40i's with and without factory bracing Quick and easy installation NOTE: This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA.

HP Gain: +13hp
Trq Gain: +13ft-lbs
Airflow: +28% over stock

aFe has engineered the Momentum GT intake to outperform the stock air box and deliver substantial power and torque gains over the factory system. The B58 3.0L Turbo benefits from aFe's oversized cotton filter element in a Rotomold plastic housing that blocks heat saturated air while flowing more volume of cooler dense air. The system has been CAD designed to achieve the maximum volumetric flow rate into the turbo. The intake tube is a smooth, unobstructed single piece from the air inlet to the airbox and incorporates a port for the air flow sensor. aFe's advanced engineering and design have made this a direct bolt-in intake upgrade.

The aFe filter has been designed specifically for this application and uses aFe's high flow/low maintenance design. The ProDry S filter has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe Pro5R filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

Features:

  • +13 HP and +13 lbs. x ft. Torque max gains
  • Outflows factory intake by up to 28%
  • High Quality One-Piece Roto-Molded Sealed Housing with Auxiliary Air Scoop
  • CAD-Designed Roto-Molded Intake Tube
  • Lightweight high gloss, clear-coated 2 x 2 twill-weave carbon fiber trim on housing for styling
  • Built-In Sight Window Provides Easy Inspection of Filter Without Disassembly
  • Pro 5R oiled 5-Layer Progressively Finer Mesh Cotton Gauze Oiled Media for Maximum Performance
  • Unique (Patent Pending) Filter-to-Housing Interface for Easy Installation
  • No Cutting or Drilling on factory Parts for Faster Installation
