Question about this product?

We're happy to help.

The Eventuri BMW E9X M3 (S65) Black Carbon Inlet Plenum – Gloss is a precision-engineered upgrade developed for one of BMW M's most celebrated naturally aspirated engines. Designed specifically for the 4.0L S65 V8, the carbon plenum replaces the factory plastic assembly with a motorsport-grade alternative that enhances induction sound while significantly elevating the appearance of the engine bay.

Constructed entirely from pre-preg carbon fiber, including the internal velocity stacks, the Eventuri plenum preserves the carefully engineered internal volume and runner geometry established by BMW. Rather than pursuing marginal peak horsepower gains, Eventuri focused on maintaining the S65's throttle response, linear power delivery, and drivability while unlocking a richer, more aggressive induction sound.

Extensive acoustic development allowed Eventuri to optimize the carbon fiber wall thickness and resonance characteristics of the plenum. As engine speed rises, the intake note builds into a sharper, more exotic soundtrack reminiscent of the E46 M3 CSL, creating a more engaging driving experience throughout the rev range.

Designed to integrate seamlessly with both the factory intake system and upgraded carbon intake components, the plenum offers precise fitment through CNC-machined aluminum mounting flanges and integrated sensor provisions. The high-gloss carbon fiber finish transforms the appearance of the engine bay while replacing the aging factory plastic plenum with a centerpiece worthy of BMW's final naturally aspirated V8 M engine.

For enthusiasts looking to retain an OEM-inspired appearance, an optional Genuine BMW OE S65 ///M V8 emblem is available. When selected, the emblem is professionally installed before shipping to ensure precise alignment and a clean factory-quality presentation.
