Formula 1 Derived Induction for the Audi R8 4.2L FSI V8

Note: This is a custom, made-to-order performance component. Please allow a lead time of approximately 8 weeks for delivery. Once the order is placed, it cannot be cancelled.

Who It’s For: This system is engineered for the discerning Audi R8 owner utilizing the high-revving 4.2L FSI V8 engine. It is designed for those who demand track-ready thermal management and maximum volumetric efficiency from their induction system.

The Problem: While the factory intake is adequate for daily driving, the 4.2L FSI V8 generates significant engine bay heat that can lead to heat soak in standard plastic airboxes. Furthermore, traditional paper filters create a pressure drop at the high RPM levels where this engine makes its peak power, limiting the engine’s ability to breathe during spirited driving or track sessions.

The Solution: The BMC Carbon Racing Filter (CRF) replaces restrictive factory components with a 100% carbon fiber support structure. Unlike plastic, carbon fiber acts as a superior thermal barrier and allows for a thinner, more rigid internal geometry that optimizes flow dynamics. This keeps intake air cooler and maintains constant pressure within the air-box, ensuring the engine receives the densest oxygen charge possible.

Why This is the Ultimate Upgrade

  • Optimized Flow Dynamics: Derived from BMC’s experience in F1 and MotoGP, the CRF design minimizes turbulence and maximizes air velocity into the plenum.
  • Superior Thermal Resistance: The 100% carbon fiber construction withstands the extreme vibrations and high-temperature environments of the R8 mid-engine bay.
  • Sustainable Performance: The multi-layer cotton filtration media is fully washable and reusable, outperforming OEM paper filters in both filtration surface area and longevity.

The Performance Promise

Professional Insight: Having worked on the Type 42 chassis for over a decade, I can tell you that induction is where the V8 truly wakes up. This BMC CRF kit isn’t just a filter; it’s a specialized tool for maintaining peak power when the engine bay starts to get hot. Note: Due to the increased airflow efficiency, ECU programming may be required to fully optimize the air-fuel mapping.

Installation & Tools

The Wrench Time

  • Estimated Time: 60-90 Minutes
  • Difficulty: 4/10 - Straightforward bolt-on, but requires patience around tight engine bay clearances and delicate carbon trim.

Tools You Will Need

  • 10mm socket and ratchet (for battery terminal & OEM brackets)
  • T20 Torx driver (for Mass Air Flow sensor screws)
  • T25 & T30 Torx drivers (for engine bay trim panels and airbox retaining bolts)
  • 7mm nut driver or flathead screwdriver (for intake hose clamps)
  • Non-marring nylon panel popper (for OEM engine trim grommets)
Mechanic’s Pro Tip (The "Gotcha"):
The 4.2 FSI V8 on the Typ 42 R8 utilizes a dual-intake, dual-MAF setup. The OEM VAG electrical harness clips become extremely brittle from mid-engine heat cycling. When disconnecting the dual MAF sensors, never pry aggressively on the release tabs. Push the connector body forward into the sensor first to relieve tension, then depress the release tab with your thumb until you hear a soft click before pulling back. Snapping these clips leads to intermittent unmetered air codes (P0171/P0174).

Phase 1: Removing the Factory Part

  1. Disconnect the Battery: Open the front trunk (frunk), remove the cowl cover, and disconnect the negative terminal using a 10mm wrench to prevent ECU fault codes and protect electrical circuits.
  2. Remove Engine Bay Trim: Open the rear glass engine decklid on your 2006-2014 Audi R8. Using a T25 Torx driver and a nylon panel popper, carefully unbolt and lift out the side engine bay trim panels flanking the dual airbox assemblies.
  3. Disconnect Dual MAF Sensors: Locate the twin Hitachi/Bosch MAF sensors on the left and right OEM intake tubes. Depress the locking tabs and disconnect both electrical plugs.
  4. Loosen OEM Couplers: Use a 7mm nut driver to loosen the hose clamps securing the factory intake accordion couplers to the dual throttle bodies and airboxes. Disconnect the small vacuum breather lines attached to the factory piping.
  5. Extract Factory Airboxes: Remove the mounting bolts securing both OEM air filter housings using a T30 Torx socket. Pull the left and right airboxes straight up to release them from the lower rubber mounting grommets, then lift them clear of the engine compartment.

Phase 2: Installing the Air Intake Carbon Racing Filter Audi R8 4.2 V8 Quattro HP 420

  1. Transfer the MAF Sensors: Using a T20 Torx driver, remove the factory MAF sensors from the OEM housings. Carefully transfer them into the new carbon fiber intake housings, ensuring the internal O-rings seat flush and the airflow direction arrows point directly toward the throttle bodies. Fasten using the supplied hardware.
  2. Mount Lower Brackets & Carbon Housings: Seat the lower carbon racing filter assemblies onto the factory rubber mounting grommets on both Bank 1 and Bank 2 sides. Secure the mounting brackets using a 10mm socket, snugging the hardware down without over-torquing against the carbon weave.
  3. Install Silicone Couplers & Breathers: Slide the multi-ply silicone couplers over the twin throttle bodies and intake pipes. Reattach all factory vacuum and PCV breather lines to the integrated CNC bungs. Tighten all worm-drive clamps firmly with a 7mm nut driver to eliminate any post-MAF unmetered air leaks.
  4. Reconnect MAF Harnesses & Reinstall Trim: Reconnect the electrical harness plugs into both MAF sensors until the locking tabs click securely. Reinstall the Audi R8 engine bay side trim panels using your T25 Torx driver.
  5. Reconnect Battery & ECU Throttle Adaptation: Reconnect the negative battery terminal using a 10mm wrench. Turn the ignition to the ON position (do not crank) for 30 seconds to let the throttle bodies align, then start the engine. Do not touch the gas pedal for at least 20 seconds while the ECU learns base idle trims and adjusts to the increased airflow of the carbon racing intake.
