Disclosed is an intake distributor for an internal combustion engine that includes an integrated heat exchanger. This exchanger includes a support plate that ensures its rigid mounting in the distributor and peripheral seal that form an essentially continuous circumferential airtight barrier between the exchanger and the distributor, peripherally dividing the interstitial volume into two. The subdivision plane of the interstitial volume is perpendicular in relation to the plane of the support plate, and the peripheral seal consist of two complementary components that are connected to one another and made integral with the exchanger.
