Do88 high performance intercooler designed for easy mounting on your BMW.

Significant advantages with the do88 high-performance intercooler compared to the OEM intercooler:
– Greater volume of the nucleus, 15517 cm3 vs 6933 cm3: 124% larger!
– Larger front cooling area, 1151 cm2 vs 658 cm2: 75% larger!
– Airflow at 0.15bar/2.18psi pressure drop: 498 CFM (354 CFM), 41% more!
– 13 HP peak power gain! Measured on 335xi N55 with Stage 1 tuning.
– Lower post intercooler air temperature under the same conditions: 43°C (58°C), 15°C less! Measured on 335xi N55 all stock except the intercooler.

This intercooler is built to offer the best cooling efficiency in difficult conditions. Made exclusively of aluminum with continuous welding, it guarantees reliability and resistance when you really need it. The increase in core volume improves cooling efficiency and lowers the temperature of the intake air.

The stock intercooler plastic air guide will need to be cut (see instructions) to make installation of our large intercooler possible. This is required for most aftermarket intercoolers with a large stepped design like ours. When the plastic air guide is cut, it leaves a large gap at the top of the intercooler that allows valuable ambient airflow to slip past the intercooler core. We couldn""t accept this, so we designed a plastic air guide that prevents this from happening, it is fixed above the intercooler core (this air guide is included in the kit).

This intercooler comes with everything needed for easy installation. Of course, bolts, washers, hoses, clamps, J-tube, air guide and installation instructions are included.
