Over 13 CFM more airflow than factory intake plenum! Beautiful Carbon Fiber construction with a roaring induction sound!
At Turner Motorsport, all our Carbon Fiber Intake Systems are top-of-the-line custom-engineered products that we developed in house. Our engineers took it upon themselves to design a prettier, cost effective Carbon Fiber Intake Plenum for S65 owners to compliment our E9x Carbon Fiber Intake System while retaining OEM features. Our S65 Carbon Intake Plenum is no different. Our Carbon Fiber Intakes start with a 3D scan of the factory intake and engine bay. Our Engineers use these 3D images of the chassis to design the intake plenum in SolidWorks modeling software. Using a Flow Bench, the Intake Plenum is then airflow tested against the factory intake, to ensure optimal airflow improvement against stock. The final product is a beautiful and functional Carbon Fiber Intake Plenum, CAD designed for perfect integration with the OEM inlet ducting and stock mounting locations. Our Carbon fiber Intake trumpets flow an average of 13 CFM over the stock BMW intake.
Our E9X M3 S65 Carbon Fiber Intake Plenum is made from 100% high grade prepreg 2x2 twill weave carbon including the internal trumpets, this plenum replaces the OEM plastic plenum allowing the naturally aspirated BMW V8 engine to generate more inductions sounds taking the driving experience of the M3 to a whole new level. The raw V8 rumble gives the M3 an almost CSL like sound and is truly an intoxicating experience. We went through several iterations using different carbon thicknesses to fine tune the sound and the resulting plenum generates an almost unbelievable induction volume and tone.
Our Carbon Fiber Intake Plenum can be used with the OEM airbox or any aftermarket intake system. Paired with our E9X M3 intake system, you're sure to upgrade the look and sound of your S65 engine.

Airflow efficiency and maximizing the potential of the stock intake design were the keys to development for the Dinan S65 intake. Dinan improves on the factory air box system by using a larger K&N filter combined with a precision molded carbon fiber intake tube. The increased amount of air feeds the engine and elicits a slightly more audible and sporty tone over its stock counterpart. Dinan claims 8hp and 5ft-lb torque gain with this kit.
For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This intake is worth 3 points toward your Dinan badge.
