Hot Air Intake (HAI) on a Mini Cooper S R53 JCW John Cooper Works using a custom K&N RU-1550 Filter

A controversial modification, where the airfilter is situated right in the hot air from the engine bay. But the idea behind this modification is the least amount of restriction in the intake, meaning less pressure drop = more power! This was tested on NAM (NorthAmericanMotoring) forum and the results where interesting. Side effect: louder supercharger whine, which is a good thing on a Mini Cooper S!
You need a universal K&N RU-1550 filter, a jubilee clamp and some rubber pieces. Thats about it...

Nicht gut. Motor bekommt zuviel Warme Luft besser im Kasten lassen und die hintere Luft ansaugung vom Filter Kasten größer machen . LG

Check the results which were measured in the thread on MBWorld. Even though that also would be my first guess, the results are very interesting. If the car is moving the incoming air does not have a time to heat up extra in the engine bay (only by the supercharger), meaning the IAT can be the same as with a normal intake. When the car is stationary, then the incoming air has time to heat up extra before its sucked into the airfilter.

Yes would 100% only recommend when moving but for long periods that will be an issue. I have a k&n typhoon mounted into the back where the stock is with a cut out and it makes the supercharger very loud. Probably a better bet

@@ryanclarke4448 Depends on your personal preferences. In the end I went with a bigger throttle body and created a custom intake with a big airfilter. Picture 1: flic.kr/p/2kPhRQt . Picture 2: flic.kr/p/2kHaM3W
