The small factory unit heat-soaks quickly under hard use, robbing power. The AMS Performance BMW M340i B58 Heat Exchanger is a direct-fit upgrade that keeps intake temps low and power consistent whether you're drag racing, running high-speed pulls, or living in a hot climate. It slides into the factory mounts and connects to the existing coolant lines — no cutting or drilling.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMotorsport-grade dual-pass heat exchanger core\u003c\/li\u003e\n\u003cli\u003e54% increase in core volume over stock\u003c\/li\u003e\n\u003cli\u003e122% added coolant capacity for greater thermal stability\u003c\/li\u003e\n\u003cli\u003eCNC-machined 6061 T6 billet aluminum end tanks\u003c\/li\u003e\n\u003cli\u003eOEM-style fitment features for secure, factory-style mounting\u003c\/li\u003e\n\u003cli\u003e5mm tall louvered fins for maximum heat-transfer efficiency\u003c\/li\u003e\n\u003cli\u003ePlug-and-play install using factory hoses, clamps, and mounting points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFully assembled direct-fit heat exchanger\u003c\/li\u003e\n\u003cli\u003eComprehensive installation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRecommended companion: \u003ca href=\"\/products\/ams-performance-bmw-b58-intake-manifold\"\u003eAMS BMW B58 Intake Manifold\u003c\/a\u003e.
