Overview:

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:

  • 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

Huge Upgrade!!!
After just a week of using this mouse, I can confidently say this is the best peripheral purchase I have ever made. I initially wasn't in the market for a new mouse, until my scroll wheel broke on my razer mouse. I decided to just pull the trigger on the X2 Superstrike instead of purchasing another razer mouse. The mouse material feel is excellent, and the wheel is great as well. I've also seen some reviews disliking the skates on the X2 Superstrike, however I personally found them to be great. The haptic feedback mouse click seemed a bit gimmicky before I actually used it. Right off the bat, the mouse click feels incredibly responsive and similar to that of any high quality mouse. You get enough feedback and it doesn't feel that much different from a regular mouse click. But, you also have optionality to adjust a ton of settings, like accuation, feedback strength, etc. For gaming, with the right settings, this genuinely feels amazing, and that's before the performance upgrade. As many other reviewers have noted, it noticeably decreases latency on top of all of this. Another huge perk with this mouse I found, was that it's almost dead silent as well. No more loud clicking! My only critique with the mouse are the side buttons and the size. The side buttons are the only part of the mouse that feel "cheap". Because I use the side buttons often in competitive games, I notice it a lot more than probably most people would. I also have large hands, and this is the smallest mouse I have used. I got used to it pretty quick, but the mouse is on the smaller side. Nonetheless, if you are looking to upgrade your mouse and have the money, I would 100% recommend. This feels as impactful as going from a 60hz monitor to a 144hz+.

Works so well I got a second one!
Size: One Size
I rarely write reviews but I came here specifically because this mouse is great! As someone who is technologically challenged I appreciate everything about it-- I bought one of these 5 years ago and use it heavily everyday, it still works like a dream which is why I bought a second one to use on a separate computer. Started using this new one and it was just as easy to set up as the first one, just plugged in the USB piece and was able to use it immediately, no further setup required. As a bonus, it already came with batteries like the last one did (by the way I never turn off my 5 year old mouse and the same batteries are still in it working great). Smooth operation, ergonomic, easy to use, and portable!

This is a GREAT Mouse!!!
Size: One Size
This is a great mouse !!! I purchased it almost 6 months ago and it is still working smoothly. I found that Logitech has great products that last. I like all 5 of the functions and use them all on a regular basis. This is perfect for right handed people as it has great gripping as well as fits nicely in my hand

Have to use the USB Receiver on the Front of Your PC
Size: One Size
This is a great mouse as long as you plug the little USB receiver into the front of your pc and not the back. Plugged into a front port, and the thing just flew, smooth as silk. I moved the receiver to a port on the back, and it got choppy, would freeze, and was really slow.
