DO88 Performance Air Intake System

  • BMW M2 Competition – 2019-2020 – Model: F87
  • BMW M3 / M3 Competition – 2015-2018 – Model: F80
  • BMW M4 / M4 Competition / M4 GTS / M4 CS – 2015-2020 – Model: F82 F83

The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X has two air filter boxes that feed the turbos with fresh air. The OE air filter boxes have panel filters that are quite small and therefore quite restrictive for the air flow.

Our goal when designing this new intake system was that it must be enclosed, so it does not draw hot air from the engine bay which many aftermarket intake systems do. If the intake system draws hot air from the engine bay it is directly equated with warmer charge air (higher IAT). During all tests we have carried out during the development of our entire BMW F8X M2C/M3/M4 product range we see clearly how the power band is directly equated with the IAT (Intake Air Temperature) and turbo inlet restriction.

When designing our upgrade intake system, we started with 3D-scanning the engine bay on our M3 Competition. This gave us an exact 3D-model of the available space to design our intake system in. We found that we could use large double cone BMC air filters with large filtering area for high flow not just when new (small filters starts to flow worse after short usage). We could also use 3” (76mm) tubing which we designed with as few and smooth bends as possible to reduce the air flow restriction. To eliminate hot air from being drawn into the air filters we designed heat shields and lids that together with rubber seals makes our system feed the engine with nice cold air. Our intake system uses the OEM fresh air inlet ducts that feeds the air filters with fresh air from the grille. We have tested these, and they are not a restrictive part in this system and with the pressure zone that builds up behind the grille at speed adding scoops will not make much difference.

Our intake pipes are manufactured in 76mm (3”) mandrel bent seamless aluminium pipes. Both the intake pipes and heat shields are finished with a tough matte black structure powder coat. For the air box lids we went for a design made in a lightweight polycarbonate material with a nice satin black finish.
All these improvements have resulted in an impressive +10 hp top power gain and in the mid-range RPM we see up to +20 hp / + 40 Nm. This test was performed on our M3 with a BootMod3 Stage 1 (93) tune.

Significant advantages with do88 performance intake system (stock comparison numbers):

  • +10 hp peak power gain!
  • +20 hp / + 40 Nm increase in the mid-range RPM!
  • 769CFM air flow at 0,025bar/0,36psi pressure drop (678 CFM), do88 13 % higher!
  • The BMC filters are regenerable for long life!
  • Improved intake sound! If even more intake sound is desired, the system can be used without the lid on the air filter housing. This will in some conditions give higher intake air temperature.

Extra deep queen sheet set 6 piece
Color: 18 - Navy Blue, Size: Queen
These sheets fit my 17" mattress perfectly. They dop pop off even after several days of getting in and out of bed. On occasion they do need to be pulled down. They are a great value for the money, I will be buying more in different colors. I love that they are wrinkle free and so soft. They're great if you have other colors to switch the flat or fitted sheet to create a new look.

Decent sheet set with truly deep pockets. VERY soft and comfy!
Color: 16 - Light Sage Green, Size: California King, Color: 16 - Light Sage Green, Size: California King
The sheets seem to be of decent quality (maybe a little on the thin side). I ordered the light sage green. They seem to have a bit more of a yellowish tinge than I expected but not too bad. I washed them as soon as they arrived and was dissapointed to see several spots on the fitted sheet. I might have blamed something in the wash cycle but they were washed alone in a clean machine and another reviewer also noted what looked like "oil spots" so I am assuming something during the manufacturing process? The sheets truly do have deep pockets! I have a deep mattress plus a topper and the fitted sheet accomodates well. The set came with 4 pillowcases, which I didn't need but some extras never hurt! I would say examine the sheets before you wash them so you can return them if they have stains. Update* Having slept on these sheets for a few days, I have to say they are extremely soft and comfortable!

Microfiber Has Come a Long Way
Color: 22 - Spa Blue, Size: Queen
I have one of those beds where the head and foot of the bed can be raised or lowered as needed, much like a hospital bed. Except in this case, the mattress is soft but supportive and very thick. If you measure the side from the top edge to the bottom edge of the mattress, it measures a bit over 12 inches. That means, if I want the mattress to actually stay in place it needs to have at least a few inches to tuck under, or it just pulls loose. Many sheets that advertise that they are "deep pocket" sheets often barely go around the mattress, and even clips don't help keep the bottom sheet on. It also means more difficulty in the first place to make the bed if I have to do it myself (I have a "hospital bed" for a reason). I did have two sets of sheets that I loved and were just deep enough to stay on fairly well, but I have had them for several years now, and they have started to get a bit thin in spots and the elastic on the fitted sheet is not as taut as before. Sheets are expensive, but I also have a sensitivity to rough and scratchy material, so the texture had to be something I wouldn't find irritating. The last time I bought "microfiber" sheets was probably when "microfiber" was a new thing, and it usually was some kind of knitted, stretchy material like a t-shirt, but had a tendency to pill badly after a few washings. Still, I needed sheets, and it was winter, and those stretchy knitted sheets were soft and warm, so I ordered two sets of the Extra Deep Queen Sheet Set--one in white, and the other in "spa blue". When they arrived, I was very surprised to see that the quality of the fabric actually mimicked very fine cotton sheets. They were brand new as expected, and they didn't smell or anything, but I do wash things like towels or sheets and some clothing before I use them. They weren't really dirty, so I just washed them in a small amount of detergent and cool water. The directions suggest gentle cycle, but I have a "bulky" setting on my washer that seems gentle enough on sheets but helps avoid issues like the load getting off balance in the tub. I dried it on the low, delicate setting with a sheet of fabric softener to cut down on static and because I wanted a nice scent. The sheets came out beautiful, and have since been used and washed again, and they so far, look and feel even more luxurious than before. I especially appreciate that the manufacturer but a label on the fitted sheet to indicate that the side that was to go on the top/bottom of the mattress. The sheets are VERY deep. More than I require, but now they stay on the bed, no matter how far up or down I move it, or how much I toss and turn. I also bought a set of sheets by another brand, but I really should have just paid the few dollars extra for another set of these. If you are used to those 800-count Egyptian Cotton or those fancy silk and bamboo blend sheets, you're probably going to hate these. But if you ever had to settle for sheets from Dollar General or Walmart, this is going to be a definite upgrade. (My favorite sheets from before I think I ordered online from Sears or Kohl's that were some kind of cotton and synthetic blend. ) Overall, for basic soft, comfortable sheets I can recommend these. They seem to be very warm, so I wonder how "breathable" they would be in the summer, but I tend to be very cold all the time anyway. I love these sheets so far. I'm tempted to order one more set if the other brand ends up being too annoying to deal with.

Perfect set of sheets
Color: 25 - Burgundy, Size: King
This set of sheets were perfect! They are soft and easy to put on our King size bed which has deep fitted corners. The price was great too!! The burgundy looks just like the picture. They are wrinkle resistant- I washed and dried them before using them for the first time and they were wrinkle free. They are not heavy in weight.

Great Sheets
Color: 35 - Lavender, Size: Queen
I really thought the sheets were really nice. I have been looking for good sheets that didn't cost and arm and a leg. The deep pockets are great. I have a mattress that has deep sides, plus I have a topper on that, so the sheets fit great! They are cooling and comfortable to sleep under. Also, I was able to get the color I wanted, lavender. I will be buying another set and do recommend them highly!
