DO88 performance side mounted charge cooler for the intercooler system, designed for an easy drop-in-fitment in your BMW M3 / M4 F8X.

The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X uses a Top mounted water-cooled intercooler instead of an “regular” air-cooled intercooler. The coolant in this system has its own separate cooling circuit combined of two parallel connected radiators and a pump. The larger one of these two parallel connected radiators is positioned in the front of the centre cooling module, the second smaller one is located in front of the right-side wheel arch.

Reducing the water temperature in this circuit is directly equated with improved cooling of the charge air (lower IAT). Due to this reason, it is important to have high performance radiators in this system to maintain as low and stable IAT as possible during tough driving. 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 peak power is directly equated with the IAT (Intake Air Temperature).

When designing our upgrade performance radiator, we started with 3D-scanning the space in front of the right wheel arch of our M3 Competition both with and without the bumper. This gave us an exact 3D-model of the available space to build our radiator in. We found that the size of this radiator could be increased considerably both in frontal area and thickness if we also designed a new air ducting between the radiator and bumper cover.

Our final design have a 68mm thick dual row core with multi-channel tubes. We have kept the OEM style single pass flow layout. Our design extends both the core height and thickness by 28mm, all this totals into a frontal area increase of 18% and core volume of a massive 100%. To make it possible to install this massive radiator we designed a beautiful carbon fibre air ducting that is manufactured from prepeg material in autoclave process. Our radiator has a drop-in installation with the OEM cooling lines.

These improvements have in our tests resulted in a 5°C IAT reduction in combination with our side mounted radiator upgrade.

All this hard work result in a product that in one way or another really will enhance the performance of your vehicle no matter if it is a standard car or a heavily modified monster! On track, on street, on strip, this radiator will be your true companion!

      Firm and comfortable
      Item Package Quantity: 2, Size: Standard
      These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

      Quite good. I am actually surprised. Too small for queensize
      Item Package Quantity: 2, Size: Queen
      These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

      These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

      amazing.
      Item Package Quantity: 4, Size: Queen
      WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!
