Our VAC CSL Carbon Fiber Airbox Package includes our VAC-CSL box and an ECU tune
so you can directly replace the OE factory airbox, eliminate the MAF sensor, and improve performance
while dropping weight! In this kit we include everything you need, including adapters,
fittings, air temp sensor, and an ECU tune so you're up and running reliably as soon as possible!
Our comprehensive kit, and software, along with the beautiful craftsmanship of our CSL-Style Air Box makes for an excellent combination when exceptional performance and exotic esthetics are key: This is more than an air-intake; double digit power gains, artisan craftsmanship, and sound like you have never heard propel your car into a whole new level of performance, sound and visuals.
No longer do you have to purchase an airbox overseas, battle with low quality
kits that are far from comprehensive, buy a separate tune, or wait for cheaper
copys of our system.
Our quality is unrivaled, with excellent fitment and durability that is both
street and track proven. Our kit is specifically made for converting a non-CSL E46 M3 into a near perfect replica, with even more flexibility so you don't have to hunt down the expensive parts from BMW that are no longer available, or simply too costly.
This is teh ultimate CSL conversion package...

'CSL' Complete Airbox & Tune Conversion Kit
Along with a VAC flash to you ECU, you can achieve the exotic, naturally aspirated performance you crave on your S54! Reliability and performance live in harmony.
Owners of the E46 M3 and S54 powered vehicles know; it has been a challenge for many tuners to improve on BMWs factory power output and delivery.
The CSL was BMWs ultimate achievement with the S54 offering true motor-sports performance on the street, or dominance on the track.
As an exact-performing replica of the OEM box with some proprietary tweaks to allow simpler installation on
non-CSL vehicles, our CSL box utilizes the 200mm intake diameter, internal BMW Motorsport panel filter (click above to add), fitting for air temp sensor (included), and elimination of the mass airflow sensor as on the CSL.
Also can be fitted to the Z3M Coupe & Roadster.

VAC Tech Info:
Q: Can this run on my factory BMW ECU?
A: Yes! Includes our custom Alpha /N software. Engine functionality is just as reliable and smooth as the OEM BMW E46 M3 CSL with our excellent software. We have different tunes available, please make sure you have a compatible engine and exhaust configuration before you order.
Q: Can I use this with my Supercharger/Turbocharger kit?
A: No, it is for use with N/A tuning only.
Q: What else will I need for this intake to function?
A: Our kit is the most comprehensive available! It includes the needed fittings and sensors, hoses, and the correct tune to adapt to a non-CSL or Z3M model that others who just sell boxes don't include.
This kit can be used with the standard E46 M3 bumper, or modified for use with the CSL M3 bumper & CSL-cold air plumbing. We can also include a Cold Air Adapter so that you can use your OE Non-CSL cold air duct!
Q:Is this an exact replica of OEM?
A:We have revised our Airbox to be an exact replica of OE in performance, except that it now is a perfect replacement for Non-CSL model cars: fits in Z3M and E46 M3, and does not require you to
disassemble the factory AFM to harvest the Air Temp Sensor or use the CSL breather lines.
Our carbon weave and sticker are now a excellent match for OEM, and its nearly
impossible, unless side by side to tell them apart- even then its difficult.
All boxes include new trumpets so your core trumpets do not have to be cut up from your original box.
