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.

Wait to see
I am just starting to use it and I have to use it for a couple of weeks to help me know if it’s works but what I notice after applying it to my hair it’s just makes it so smooth and soft

Lashes like Garbo
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer, Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I think this might be my new go to mascara. I have the teeniest tiniest lashes ever, they are straight and stick out from my eyelids and without mascara I look like I have no lashes so it’s a struggle finding mascaras that make my lashes look lush. Let me start off by saying that the primer is amazing. As soon as I put it on my lashes grew over twice in length! It didn’t clump and separated my lashes like whoa( the clumping with these lash fiber or extra lengthening mascaras is always horrendous so that was a wonderful surprise), it dried in about 20 seconds and then I put on the coal black mascara. Vavoom ladies! Instant fabulous lashes. So far I have experienced zero flaking after wearing for long periods of time , it hasn’t smudged or melted when I’m dancing up a storm or getting my workout on and the length of my lashes is practically miraculous. It is not cry proof. It’s super easy to remove and doesn’t tear out any of my eyelashes though, so that’s another plus! Also, I have celiac disease and a host of other random allergies and am allergic to SO MANY products it’s ridiculous, but luckily I am not allergic to this magic mascara. I recently discovered that this doesn’t smudge on my bottom lashes either! I’m almost 40 and I have never found a mascara that didn’t smudge on my bottom lashes. I’m so oily that even waterproof ones didn’t work! I stopped wearing it on my bottom lashes for anything but photo shoots after 20yrs old because the smudging made me look like an old lady with terrible makeup skills,but now I can once again rock liner on my bottom lashes! I included a terrible picture ( I hate getting my picture taken!) and tried to crop it so you can get an idea of how amazing this mascara is( look at those lashes practically touching my brow bone!),because I know I always want to actually see the results of people using the product, so hopefully it helps. :-) Ps: I don’t have mascara on my bottom lashes in the pic as I didn’t discover it was even a possibility for me until I bought a tube for my bestie ( another oily faced queen)and she told me there was no smudging:-O

Mascara is good, but don’t expect the best - smudges & flakes sometimes
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
This mascara is very good for lengthening when you use the primer. I’m not sure I’ve noticed a volume/thickness increase, but have noticed lash length does look longer. I usually give it about 30 seconds for the primer to dry before using the mascara, otherwise it does clump a bit. I would also recommend wiggling both wands along your lashes during application to avoid clumps. In general I do like this, but noticed a few other important points: it will definitely run a lot if you get it wet (e.g. rain or crying), it will flake or smudge a little by the end of the day - especially if you rub your eyes, and while it does not make my eyes itch, I found it best to put in my contacts AFTER the mascara is fully dry. I’ve accidentally got some mascara a few times in my eye with the wand/trying to smooth out clumps and it totally made my contacts (daily wear type) useless after that. That all probably sounds like the mascara isn’t worth it, however I still actually like this mascara. I’d say it’s perfect for an average day’s wear, just not an extended day or in some cases. It does come off fully for me.
