BackgroundThe B58 engine, introduced with the F-series, has proven to be a real gem of an engine, capable of high outputs with great character. However, there are a few week points that needs addressing, both for performance and reliability. The B58 comes equipped with a water-to-air charge cooler that is coupled a with front-positioned heat exchanger (water radiator). The heat exchanger serves to cool the water circulating through the charge air cooler, which in turn helps dissipate heat from the charge air before it enters the engine. The charge air cooler is integrated into the intake manifold on the B58, making it an intricate and dense construction, demanding accuracy in the design and execution by us as an aftermarket producer.
Challenges with the factory components
Owners of tuned B58 engines often confront the issue of rapid heat soak in the charge air cooling system, particularly when the vehicle is used for track days. Elevated intake air temperatures may prompt the ECU to decrease the power output, or even switch the car into limp-home mode. Regular spirited street driving can also cause similar issues.
Additionally, the factory installed direct injection system, with its obvious benefits, is not well suited for high horsepower applications or ethanol flex fuel usage. To be able to inject more fuel, many turn to installing port fuel injector spacers between the intake manifold and the cylinder head. The downside with this solution is that it positions the injectors in a funny angle. As a result, the fuel hits the walls of the intake runners, leading to potential fuel puddling.
As is often the case, factory components can become limiting factors when you strive for high power levels, particularly in terms of airflow. The factory (OE) intake manifold is such a component, that not only restricts airflow but also poses a significant risk of cracking under high boost levels, due to its plastic construction.
The do88 solution
Bar&Plate coreOur manifold features a Bar&Plate design air-water core, which incorporates densely stacked cooling fins, offering great heat transfer. The core is precisely 102 mm (4 inches) thick, maximizing its effectiveness for this specific application. Both the air and water fins´ characteristics have undergone careful evaluation to achieve the ideal balance between optimal cooling and airflow.
Innovatively designed cast end tanks
The charge air and cooling water are evenly distributed across the core through carefully designed, cast end tanks. The development of these end tanks involved a comprehensive process, including 3D-scanning, multiple design iterations followed by Computational Fluid Dynamics (CFD) analysis and 3D-printing, before arriving at the finalized prototype. We opted for cast end tanks over CNC-machining. Casting allows complex shapes that better serves the desired function. To us, maximum performance supersedes the bling factor!
Engine Cover Compatibility
A goal during the development of our do88 manifold was to keep compatibility with the standard engine cover. It goes without saying, many enthusiasts prefer to maintain the original appearance of their engine bay if possible. With this in mind, we invested significant effort to design a charge air cooler that not only makes a massive performance upgrade, but also have the possibility to use the engine cover. We managed the challenging task of accommodating our manifold under the engine cover.
Moreover, it is possible, with modifications, to also integrate our auxiliary fuel rail. To do this, the sound-dampening material beneath both the engine cover and the hood must be removed. Additionally, the standard engine cover mounting pins must be replaced with longer ones, which we include in our kit. Note that installing the engine cover in this elevated position brings it very close to the hood; slight trimming or reshaping of the hood's support structure can be done to increased clearance. We have verified this compatibility exclusively on the BMW 340i F30/F31 models.
The devil is in the detail and to date, this unique feature sets the do88 kit apart from the competition. High performance builds tend to be made by enthusiasts that value the appearance equally as high as the sheer performance without compromise.
Key Features
Versatile Manifold Design: From Fuel Injection to Power ModificationsOur manifold outlet tank is pre-configured to accommodate auxiliary port fuel injection. A custom-made fuel rail with female AN-8 threads is available to purchase separately, this easily installs to the outlet tank. We designed it for compatibility with Injector Dynamics ID1050x-34-14 or Bosch EV14XK (short) fuel injectors. If you opt to not use port fuel injection, we provide injector blanking plugs for your convenience. Additionally, each cylinder runner on the outlet tank is equipped with a 1/8 NPT port, suitable for nitrous or methanol injection - a commonly used power modification for the B58 engine (sealing plugs are included).
Extra Measurement & Vacuum Ports
Integrated into the side of the manifold inlet tank, do88 has incorporated a 3-port pad directly into the casting. This feature offers the flexibility to measure additional parameters or serve as an extra vacuum source. Should you choose not to utilize these three 1/8 NPT ports, sealing plugs are provided in the included hardware kit.
Advanced Thermal Management
Included with the intake manifold is a special thermal barrier spacer, engineered to insulate the aluminum intake manifold from conductive heat transfer from the cylinder head. This barrier effectively lowers intake air temperatures (IAT´s), enhances the efficiency of the charge air cooler, and helps minimize the issue of heat soak. Unlike the OE plastic intake manifold, the do88 manifold is made from aluminum, capable of withstanding higher boost pressures. The thermal barrier spacer reduces the conductive heat transfer, otherwise typical to aluminum components. The spacer features a robust seal, achieved through custom-made, high-specification FKM-silicone O-rings. These O-rings are installed in precision-machined grooves for a secure fit. This approach offers a significantly better seal compared to other competitors´ methods, which often rely on less reliable sealing agents.

He was OBSESSED!!!
Size: Large, Color: Dinos Frills (Gray), Size: Large, Color: Dinos Frills (Gray)
Our year and a half old lab was excited the moment he saw it come out of the box ! He had many toys that he tore into shreds within a day so this was his first “heavy toy “ that wasn’t easy to tear .
I think he loves the design and feel of it , as he carried this thing EVERYWHERE and even to bed . Him and his sister share toys but this was his , he claimed it lol
Now if it wasn’t for us telling him to stop trying to kill the Dino he could have easily tore into this thing within a couple of days . However since he started chewing gently he became obsessed with the squeaker , and used that as an alarm that he was up every morning in bed 😂
The quality of the product is actually pretty good but it’s not bullet proof, and our smart dog was able to sneakily tear a whole in the nose and some how pull out the stuffing .
All in all I would definitely buy another toy from this company because they are made with quality for dogs , and lasted about three weeks longer than his average toys ! It was his favorite toy 💕

Not indestructible
Size: Large, Color: Dinos Frills (Gray)
When I googled “indestructible stuffy dog toys” this popped up. My 9 month old pup loves stuffies but destroys them quickly and eats stuffing if not caught quickly. Well, this indestructible toy is cute but my dog had it torn apart in under 4 minutes so…🤷🏻♀️

Great for Tough chewers!
Size: Large, Color: Dinos Frills (Red)
My dog is a tough chewer and absolutely loves this toy! He was able to get a little stuffing out of the leg so far and it’s been about a week. This might sound like a short amount of time but it usually takes him under 15 mins to unstuff a large toy even if they are advertised for “tough chewers!” This is a very large size toy and would be good for any larger breed. He carries it around the house and constantly keeps his Dino with him. Since Ive found GoDog toys I’ve only been purchasing them because of their durability. I’ve tried Kong and Bark toys previously and they just do hold up long and are usually more expensive. This toy is a great value and dogs love them!

LOVE this brand. Have many of their styles. This is basically an unstuffed toy.
Size: Large, Color: Dinos Frills (Gray)
I have about 10 -12 different styles of the GoDog brand toys. It is like Xmas when my Malinois dogs get a new GoDog toy. Have loved this brand for many years and have some toys which have lasted 5-6 years -- minor "surgeries" stitch they back together -- until I retired them. They have never just worn out. Just to be clear:
THESE TOYS ARE NOT CHEW PROOF. NO STUFFED TOY IS CHEW PROOF.
However, this brand of stuffed toy is more chew proof than other brands. But if you are looking for a chew proof stuffed toy be advised -- IT DOES NOT EXIST!! No fabric is chew proof. Even if they invented such a fabric I would not want to ruin my dog's teeth by letting them try to chew through it. Protecting one's dog's teeth should be the highest priority.
If a dog can chew through a PLASTIC KENNEL and even METAL WIRE KENNELS (yes, it happens) then they can easily chew through a puffy, fluffy stuffed toy. The "Chew Guard Technology" language may be misleading to some customers who are disappointed in the brand. I defend the brand and have used it for many years. No, I don't get paid or get free toys.
Since I have had many styles within this brand and even have the pink version of this style I thought I knew what I was getting. This is basically a toy without stuffing which some people prefer. For whatever reasons my dogs prefer toys that are stuffed. Really stuffed with a firm density that they can sink their teeth into. So this toy will be OK. I can tell it will not be one of their beloved toys like some of the brand's other styles such as the purple brontosaurus. My fault for not reading more closely and assuming the grey version would be exactly like the pink version which is fully stuffed. If they get bored with these two I keep some of the Chew Guard toys stock piled.
BTW one can wash and dry these toys. Yes, eventually the squeakers suck up some water and die but one can replace the squeakers. Also on Amazon. So I am willing to replace the squeakers a few times in the life time of one of these toys to be able to wash and dry them occasionally. Usually takes a couple drying cycles to get the heavily stuffed toys dried completely.
If you have an aggressive chewer you may wish to look into Goughnuts dog toys or other hard rubber toys that are designed for aggressive chewers. Even then, with a determined dog, the Goughnuts toys can be chewed through. I think they offer a replacement guarantee. The other brand which has some toys of hard rubber is West Paw. An excellent brand that also offers a one time replacement. Bully Sticks are another option for chewers.
PLEASE, PLEASE, PLEASE stay away from the hard plastic chew toys like the Nyla Bones. Hard plastic toys will destroy your dog's teeth over time. I learned the hard way (no pun intended) and ruined one of my dog's teeth. Vet asked if I allowed my dog to chew ROCKS !!!!!! Every tooth was cracked or fractured. Not wishing to pull teeth I had to pay for some very expensive root canals and caps. Vet's advise: If you can't dent the toy or chew with your finger nail DO NOT offer to your dog. Good advise to follow. Even some of the Bully Sticks (Costco Brand) are so hard they can chip or fracture teeth.
Best for you and your dog.
