do88 performance intercooler designed for an easy fitment in your BMW.

Significant advantages with do88 performance intercooler (OEM intercooler):
- Greater core volume: 15517 cm3 (6933 cm3), 124 % larger!
- Larger frontal cooling area , 1151 cm2 vs 658 cm2, 75 % larger!
- Air flow at 0,15bar/2,18psi pressure drop: 498 CFM (354 CFM), 41 % higher!
- Peak powergain of 13 hp! Measured on 335xi N55 with Stage 1 tune.
- Lower post intercooler air temperature at same conditions: 43°C (58°C), 15°C lower! Measured on 335xi N55 all stock except the intercooler.

This intercooler is constructed to deliver the best cooling efficiency during tough conditions. Exclusively manufactured in aluminum with continuous welds, it guarantees reliability and endurance when you really need it. The increased core volume improves cooling efficiency and lower the intake air temperature. Naturally, this being a do88 performance product, we have executed thorough, severe and continuous tests developing this product to ensure best performance. Not one compromise has been made. This intercooler is immensely optimized to the given space for an easy fitment.

The stock intercooler has quick click connections for both hoses. These connections are both restrictive for the airflow and is not ideal in terms of reliability with a high boost tune. The stock intercooler has rubber hoses and plastic J-pipe (intercooler outlet pipe).
We have redesigned the intercooler connections to conventional Ř3; (76mm) hose connections. We include reinforced silicone hoses and a 2,5; (63mm) mandrel bent aluminium J-pipe to match these connections. Our J-pipe fits together with stock charge pipe or any aftermarket charge pipe that is designed to fit together with the stock plastic J-pipe.
All these improvements result in better cooling, lower pressure drop and a much more reliable intercooler setup for high boost tunes.

The 124% increased core volume is an achievement we are proud of. It´s a remarkable difference. Perceivable, to say the least. The engine pulls better all over the revs and withstands repeated full throttle runs without building heat. The perception of an intercooler being something to upgrade only after a major engine tune is false, yet widely spread among customers and car people. During hot Swedish summer days, at repeated pulls, inspired driving or even at ordinary driving in a hotter climate area, it doesn´t take much of an effort from the engine to generate dangerously high inlet temperatures even on a standard, non-tuned, car. The cooling capacity with an OEM-intercooler is in many cases inferior which will affect the usable power outtake. The heat has to be eliminated, or else the promised output will be decreased as you start giving gas.

The stock intercooler plastic air guide will need to be trimmed (see instructions) to make it possible to install our large intercooler. This is required for most aftermarket intercoolers with a large stepped-core design such as ours. When the plastic air guide is trimmed it leaves a large gap at the top of the intercooler which lets valuable ambient air flow slip past the intercooler core. We could not accept this so we designed a plastic air guide which prevents this from happening, it is fastened on top of the intercooler core (this air guide is included in the kit).

This intercooler comes with everything necessary for an easy installation. Bolts, washers, hoses, clamps, J-pipe, air guide and installation instructions is of course included.

Do take care of your engine. Choose do88.

Perfect fit, secure pencil slot, great touchpad.
Color: Navy Blue
EXCELLENT Keyboard case. I tried several to find the right one. Tried a bluetooth keyboard by itself, but there wasn't the convenience of an "all in one". Tried another one that had a magnetic connection between the ipad and the keyboard, but the ipad was not as positionable as I needed it to be. This "folio-type" case is similar to what I use for all my other tablets and devices - slim, securely closing, perfectly fitting my 3rd gen ipad pro - AND the slot for the apple pencil is PERFECTION! The touchpad is a little stiffer than I like but then I realized I DON'T actually have to press it to use it - just a tap accomplishes the same thing. I rely on the touchpad for a lot and this case is just really exactly what I need.

good value and battery life
Color: Purple
Love this!! the keyboard has a good life on it and charges pretty fast. I at first didn't really like that it detaches, but being able to hold the keyboard in my lap and type on the screen while I sit on the sofa is actually pretty nice. the trackpad does have a bit of a learning curve, but gestures/hotkeys are all listed on the bottom so it's easy to check whenever necessary. The material of the case itself also cleans really easy. I spilled a drink on it and it wiped right off. I feel like this is a pretty good value all things considered, especially when similar products at big box stores can eb a couple hudnred bucks. The only downside is that the keyboard, while slim, does add a bit of bulk to the case. It's not a huge deal for me, but my boyfriend who also has an ipad did notice the difference immediately.

Works
Color: Light Gray
Heavy! It is a nice case and the keyboard works good. Turns off randomly, but not too annoying. This case is heavy though! It at least triples the weight of my iPad, which is opposite the reason I got an iPad Air. Too late to return, I just take the keyboard out, but it must be the magnets in the case that are so heavy.

Fantastic keyboard!
Color: Navy Blue, Color: Navy Blue
Pleasantly surprised!! And less than half the price of an ipad folio keyboard - I know, one feels like one has to stay in brand. So I was nervous about buying a keyboard that wasn't made by Apple. But to be honest, the Apple keyboards and mice have betrayed me on numerous occasions. They have not earned my loyalty and need to reassess their dubious life choices. I needed a protective cover to stop my cats doom scrolling while I am asleep. I am OK with them using the internet - even though I have had random people text me back a picture of a large feline left nostril and just the letters WFT? It is what it is. I think they are little geniuses. But they scratch the ipad surface which is annoying. So I thought, what the heck - I am about to do my RN-BSN online and need a way to make my ipad transportable while protected, and set up so I can easily bang out some homework assignments on the run. Easy set up! What a relief! Tech usually hates me - sees me coming from a mile off and starts planning to at best ruin my day, and at worst have me calling my therapist. At first I started reading the instructions and my teeth hurt from the bad translation into English. But even with that negative energy I was able to set it up very quickly. Everything just WORKED!! I know. I set a low bar. These days one has to. This time I didn't need to. The cover is sturdy, soft and coffee resistant, thank goodness. The keyboard just plops on, connects through magic and immediately makes me feel like I am not as stupid as I thought! Absolutely recommend this wonderful keyboard - I dunno who do this voodoo but I am very excited. Crack on my lovelies! Make those dreams a reality.

Great product!
Color: Light Pink, Color: Light Pink
I really love this. The baby pink is so cute! I had my hesitations because I couldn’t see if the pink would be as good in real life. It’s like a soft blush color. Honestly, I was going to drop $350 on the Magic Keyboard for my iPad Air. Which is ridiculously expensive. This is a way better alternative. It fits my iPad pen. The iPad itself fits perfectly. I thought the keyboard was going to be tacky and cheap. But it’s pretty legit too. I love that when I’m done using the iPad, the whole case protects everything, even the keyboard inside and especially the camera lense. The magic key board does not have that feature. Like that it’s magnetic too. The material is so soft to touch. I can see how it can get dirty with ink spot if not careful. Overall, really happy with this purchase!
