The OEM charge-air-cooler manifold for the B58 engine is adequate in cars with little or no modifications. However, it starts to really its weaknesses in cars that have bolt-on modifications, turbo upgrades, increased fueling (such as port injection), and performance tuning. In addition, the OEM intercooler system has been known to suffer from heat soak in demanding racing conditions such as time attack, endurance racing, drag racing, and drifting, as well as spirited driving on the street.
