E92 E93 335d ATM Cold Air Intake Kit 335D-INT-EU-O & 335D-INT-EU-D

For the N57-powered E92 and E93 335d - not the N54/N55 petrols, not the F30 - this ATM cold air intake replaces the restrictive OEM airbox with a free-flowing path to the twin-turbo diesel’s compressor inlets.

• Stage 1 & fast road fit: Works cleanly with stock ECU maps; no check engine lights, no MAF recalibration needed
• Track day ready: 8-layer oiled cotton filter (EU-O) or dry synthetic (EU-D); both flow more, trap better, last longer than paper
• No cutting, no drilling: Uses the factory snorkel location and mounts directly to the OEM airbox flange - bolt-on for the N57D30A engine
• Decat or full stage 2? Still compatible: Designed to complement aggressive tuning, not fight it
• Diesel induction note, not drone: Hear the turbos spool - not the cabin rumble
