Doorbusters BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW 3 Series E90 (2006-2011)

Turner Motorsport E9X M3 S65 Carbon Intake Plenum

Unlock the full character of BMW’s legendary S65 V8 with Turner’s in-house engineered Carbon Fiber Intake Plenum—designed to enhance airflow, elevate induction sound, and integrate perfectly with OEM components.

Delivering over 13 CFM more airflow than the factory plenum, this upgraded unit is crafted entirely from high-grade prepreg carbon fiber, including the internal trumpets. The result? A stunning visual centerpiece and a dramatic increase in induction roar—an addictive, CSL-like soundtrack that transforms every throttle input.

Engineered by Turner, Built for Enthusiasts

Turner’s development process starts with a full 3D scan of the S65 engine bay. Our engineers refine every contour in SolidWorks before validating performance on a flow bench. The plenum is then produced using a 2x2 twill carbon weave and a UV-protected gloss clear coat for a long-lasting premium finish.

Multiple carbon layups were tested to fine-tune tone and resonance, culminating in an intake plenum that produces unbelievable induction volume and a razor-sharp V8 wail while maintaining factory fitment and sensor compatibility.
