BAR-TEK® upgrade Water cooler fits BMW B48/B58

Upgrade Water cooler kit: Put an end to reduced performance in the B48/B58 engine!

You finally want to use the full tuning potential of your G Series B48 or B58 engine? The potential of the 40i, 20i and 25i models is enormous! Unfortunately, we have a bigger problem here: as soon as the charge pressure is increased, the charge air temperature also increases significantly. So as long as you are happy with the standard performance, everything is fine. However, if you want to increase the power because you simply want to enjoy all the power, the temperature of the charge air increases. What happens then is exactly the opposite of your desired result: because when the temperature rises, the performance drops.

The solution: cool air for the 40i, 20i and 25i models

The charge air in the B48B20 and B58B30 engines is not cooled down by the ambient air, but by its own cooling water circuit. We exploit this fact to increase power and performance. Because with our MW B48/B58 engine water cooler kit we improve the cooling performance so blatantly that nothing stands in the way of an extreme increase in performance!

100% more radiator volume with our B48/B58 water cooler

Our B48/B58 water cooler is perfect for you if you really want more power. With a thick 65mm core, the available space is used to the maximum. The material significantly improves heat transfer and increases the cooler volume by 100%. The special mesh allows enough air to pass through for the engine water cooler sitting behind it. The BAR-TEK® water cooler is the optimal cooling upgrade for the B48 and B58 engines.
