BMW M3 Heat Exchanger - Dinan - High Performance - '15-'18. Upgraded primary cooler for the S55-powered F80 that combats heat soak and keeps power consistent.

Developed through extensive testing, Dinan's 40mm-thick core was chosen to respect main radiator airflow while adding 60% core volume and 19% face area over stock. Average reductions measured: 9° at the intercooler water circuit and about 6° intake air temps. These improvements yield repeatable gains on the stock tune of roughly +10 hp and +20 lb-ft. Rubber isolation mounts enhance durability.
