An internal combustion engine may include a housing and at least one cavity arranged therein for receiving a coolant flow. An exhaust gas cooler may be provided for cooling an exhaust gas flow. The exhaust gas cooler may be configured as a stacked disc cooler including at least two stacking discs, an exhaust gas inlet, a cover plate and a screw-mounting plate for screw-mounting to the housing. The exhaust gas cooler may protrude into the cavity of the housing when the screw-mounting plate is mounted to the housing. The screw-mounting plate may have a spacer element disposed at the exhaust gas inlet. The spacer element may protrude in a direction of the at least two stacking discs and enlarge a distance between the screw-mounting plate and an adjacent stacking disc of the at least two stacking discs to position the exhaust gas cooler further into the cavity.

An intake adaption system for internal combustion engines of vehicles employing an aftermarket intake air assembly including high capacity intake ducting and a low resistance air filter. Intake air sensors provide intake air condition signals of filtered intake air to the engine. A CPU includes a routine for modifying the intake air condition signals of the filtered intake air to the ECM. Tables alter the appropriate sensor signal or signals to correct for the calibration and predictions made by the ECM based on the original equipment. A first table translates the intake air condition signals from the intake air sensors indicative of MAF into the engine to provide actual MAF into the engine. A second table generates a pressure offset responsive to MAF into the engine to provide the ECM with a lower pressure value than actual, avoiding a diagnostic trouble code.
