A great upgrade for the Supercharger R53 MINI Cooper S is the GP Intercooler if you're looking for that OEM look and can afford it.
With an increased size over stock you'll see a huge improvement in cooling the Inlet Air Temps (IAT's) allowing the car to hold power for longer periods of time under boost.
The GP Intercooler has one of the best recovery rates for top mount intercoolers for the R53.
An ideal part for those with reduced supercharger pulleys running more boost than stock.
Includes top cover.
