Upgrade water cooler suitable for BMW F Series B48/B58 BAR-TEK®

Upgrade water cooler-Kit: No more reduced performance in the B48/B58 engine!

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

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

The charge air in the B48B20 and B58B30 engine is not cooled by the ambient air, but by its own cooling water circuit. We utilise this fact to increase power and performance. With our BMW B48/B58 engine water cooler kit, we improve the cooling capacity so dramatically 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 to achieve more power. With a thick 65 mm core, the available space is utilised 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 behind it. The BAR-TEK® water cooler is the optimum cooling upgrade for the B48 and B58 engines.
