Race quality - Race proven

Our S54 Carbon Fiber Airboxs are designed to replace the factory airbox, improve performance and weigh only a few lbs!
These beautiful Carbon Air Boxes are for when performance is key; based off the principals of the DTM cars and E46 CSL intake, we have tested and tested various intake volumes, runner lengths and contours to find a shape that would improve on the already excellent results of the CSL intake...

With our VAC S54 Race Airbox, you have found everything you need: No longer do you have to fight with currency conversion; battle with low quality parts from unscrupulous sources, or intake kits that promise power gains and don't deliver...
The quality of this airbox is great, and it weighs next to nothing, along with perfect fitment and real-world durability.

VAC Race Style Airbox:
VAC has the intimate knowledge and experience to improve upon the OE CSL Airbox:
Our exclusive design uses a different helmholtz resonance to have a charging effect on incoming air for maximum high RPM power (just like the CSL Airbox, but with a different tuned volume and shape).
This airbox is one of the keys for making maximum power when your goal is to exceed the CSL in performance. Can be fitted to the E36 & Z3 with S54-swap with minimal modification. Our airboxes also include their own velocity stacks so no core stacks are required.
Gains another 15-20HP more top RPM power than the CSL Airbox! Ideal for the race track.

• Extremely light weight
• Improved engine output
• Much more top end HP gain than CSL box, only a 5HP low-RPM sacrifice around 3k RPM
• Compatible with OE Alpha N programmed ECU or aftermarket standalone ECU
• Exclusive to VAC design
• Blank finish, with VAC sticker you can attach if desired (new style, not pictured is included)
• Excellent quality fit & finish
