BMW M3 E90 E92 E93 S65 4.0 litre V8 Induction System Upgrade by aFe Power

Transform how your E9X V8 breathes with this premium aFe performance intake. Expect sharper pedal response, stronger mid-range pull and that addictive V8 induction note every M3 owner wants. We run this intake on our own builds and customer cars and the feedback is consistent - crisper torque delivery, cleaner airflow and a serious uplift in driving feel with a quality finish that lifts the engine bay.

Available in a stealth black tube or stunning carbon fibre, and with your choice of performance filter media, this bolt-on upgrade uses the factory airbox as a heat barrier for genuine cold charge benefits while maximising flow to the S65.
