• Port for methanol injection (1/8 -27 NPT) on the charge pipe. Plug included if not used.

This BigPack consists of an all-aluminum intercooler and a complete package with 2.5” aluminum charge pipes and silicone hoses. This package replaces everything between the turbo and the throttle body, thus providing drastically improved flow and cooling efficiency compared to the original.

The intercooler is manufactured with CAD-designed, flow-optimized cast end tanks and a carefully selected core to achieve the best possible cooling effect with the lowest possible pressure drop!

The charge pipes are made from 2.5” extruded aluminum tubing, mandrel-bent to the correct shape!

Specially designed, high-quality silicone hoses with 4-ply polyester/aramid reinforcement to withstand high temperatures and pressures.

It is worth noting that the original intercooler with its associated charge pipes was designed for the power the car had from the factory. When increasing power or during very hard use of the car, even in its original configuration, its performance is no longer sufficient. So, even with increased boost pressure / software upgrade / chipping, our BigPack will provide improved performance!

A common misconception is that you cannot get good cooling performance from an intercooler in the original placement and that a front-mounted intercooler / FMIC would be much better. But in reality, the do88 BigPack is far superior to most FMIC installations where only a core with too small a cooling area can be fitted, which often also has partially blocked airflow from, for example, a crash bar, which in many cases can result in worse cooling performance than the original.

The do88 BigPack comes with all necessary parts for installation in the car. Installation is done using original mounting points.
