Dinan BMW G20 M340i Carbon Fiber Cold Air Intake System

Part Number(s): D760-0052

Applications:

• 2019-2021 G20 M340i

Product Page(s) / Pricing: dinan.info/G20-M340-CAI

Release Date: Available Now!

Description: The M340i is an impressive car in terms of performance and style but that is not conveyed when viewing its lackluster stock intake system. In stock trim, the M340i 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 M340i 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 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 air box 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/Benefits:

• 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 air box (60% larger than stock).
• 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow.
• Quick and easy installation.

It's coming. Doing the emissions testing on it this week assuming other items dont take to long and need to be re-tested.

They are linked on the bottom of the product page on our website under the "tech resources" tab.

Will it also fit the 2021 m440i ?

Would not. The bracing on the M440i interferes with this design/lid. An alternative is under development.

What is the status or eta on the tuning device for this platform?

I do not do ETA's, especially with software, as timelines change often with new developments/requirements and additional hurdles the factory may throw in with updates, etc. That said, callibrations are done. Delivery/unlock methods are not. Progress has been slow but there has been progress.

Do I need this? No.

Do I want this? Yes.

Such is life as a car enthusiast. Continually broke as you want more "things". Give in to the urge and settle the itch. Even if it is fleeting. YOLO. =)

[12v_dub]

Looks much better quality over MST intake.

Sigh. I am beginning to think Dinan is biased against the beaver.

[TruthOne]

This looks really good and tempting . Wife will kill me.

Haha so true. I think it’s a good price so I plan on purchasing one.

Totally understand. I just hope we see it available sometime before the end of the year.

Well, we own an M340i (2 if you include an employee car) while we haven't actually been able to get a G22 in here physically to date. They seem to be incredibly rare here in AL/GA yet. All of our development so far for it has been derived from buying stock components and doing some backtracking. We do have our own beaver in the form of the M4 hitting in the next 30 days or so though so they aren't totally written off.

You and me both. Hopefully much sooner.

Hey at least it's not -17 like it is in Minneapolis right now

[franky818]

Umm... my 330i is patiently waiting for this part. Can you paint it red ❤️ I'll pay more I don't want carbon

[BobTheBimmer]

Any plans to make this available through Canadian dealers? Ready to pull the trigger but no shipping to the great white north available on your website. 😫

It'll be carbon. Sorry. =/

Canadian dealers have access to it the moment it is launched as well. Usually takes them a few days to populate websites and stuff but if you call/visit directly they can order for you. Alternatively you could order from other e-tailers that do offer international shipping.
