Eventuri Matte Carbon Air Plenum for BMW E9x M3 S65 V8

Part number: EVE-E9X-CF-PLM-MATTE

Transform the character of your S65 V8 with Eventuri’s matte carbon air plenum. This is a straight swap for the factory plastic chamber and is engineered from 100 percent prepreg carbon fibre, including the internal velocity stacks. The result is a sensational ITB induction note with a clean, motorsport-grade finish that elevates your engine bay. Volume is carefully matched to the original unit, so drivability, throttle response and smooth power delivery remain exactly as they should.

Looking for a BMW M3 V8 sound upgrade, E9x M3 carbon air chamber, S65 resonance box, CSL-style intake noise, M3 throttle trumpet cover, carbon induction plenum, or matte carbon engine dress-up for the E90 E92 E93 M3? This Eventuri unit is the enthusiast favourite for unlocking that iconic howl while keeping OEM manners.

Key reasons to choose this upgrade

• Matte prepreg carbon fibre - heat resistant, rigid and dimensionally stable
• Direct replacement - no cutting, no coding, designed to locate like factory
• Compatible with the standard airbox and performance intakes, including Eventuri systems

Construction and specification

• 100 percent prepreg carbon fibre lid and base
• Eight carbon velocity stacks manufactured to OEM length and profile
