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. 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. 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.

Dog loves them, but don't leave them unattended
Style: Small, Size: 5 Chews
My pug loves these. Be careful, they sometimes crumble into shards, so always be present. My dog has swallowed some and threw them back up.

Well made dog toy
Color: Blue
The snoops are great for our active labrador. He is a very aggressive chewer, and so far, has not destroyed a snoop yet. He has mulitples. They are a great size for filling with treats or kibble and they keep him engaged in the activity. He even likes to carry them when he does his zoomies sometimes. They are lightweight and sturdy, and the material is nice and flexible. Great toy / puzzle ball to have around for your pup!

Very durable
Color: Blue
I have never written a review but just have to say how much our Pitbull LOVES this toy. It is very sturdy very good since he is such an aggressive chewer. This is only the second product I have found that he can’t destroy in 5 minutes. It keeps him busy for a long time and plays with it long after the treats are gone which is good as too many treats and he would gain weight. Highly recommend it. He weighes 70 lbs and the largest one is the perfect size. Kibble doesn’t work as it empties out immediately. I use Beggin Strips cut to size just to fit in the hole—they will come out but not all at once and survive his chewing on the toy.

Great you made super well
Color: Blue Lil Snoop, Color: Blue Lil Snoop
This is such an awesome toy. It’s super durable strong bounces and a perfect size. We got the small. We got blue because our pup can see it. It allows for creativity and endless limits to what you can make for it to be a fun experience. It has a nice sized hole in the center which allows you to add treats and food. Pop it inward and it slightly if large enough prevents the treats from coming out super fast. The ball rolls bounces and they can grip it nicely.
It is easy to clean
The only thing I didn’t like was the way the plastic tabs were situated inside the toy as you just be careful you don’t allow it to drip inside and dog gets it. No noise just fun. Our 15lb Cavapoo loves it

FUN AND DONE!
Color: Orange
First, I looove that I could get this dog toy in my favorite color! The orange color also helps to locate it, if your doggo has rolled it somewhere you don't know.
This bowl toy is very durable, safe, and easy to pull open and fill. The only reason I don't give it 5 Stars is because the opening is so big, after it's closed, that unless you have pretty large pieces/treats in it, or jam-pack them in, they easily fall out, when my dog rolls the toy around.
What I do, is put a whole Greenie in the bowl and then add treats around it. She's thrilled to have a treat or two spill out, as she rolls the bowl around. But what really keeps her occupied is trying to get to the Greenie. This is where the durability plays such a key role! Our dog is a Pit-Terrier and an extremely aggressive chewer, but the fold in the bowl is so strong that even her attempts to chew through it or claw it out don't work. That said, I would still supervise your dog's play with this. I know, if she really wanted to, our dog could eventually chew through the strong material to get to the Greenie, but thank goodness it's too thick and too wedged in to be worth all that time. The awkward shape of the bowl also makes it hard for her to grip it in her mouth foe chewing.
For a dog's quick fun, amusement, and reward, this is a winner!!
