Default Comprehensive CSL Intake Thread

Types of Airboxes:

OEM
  • Pros: Perfect fitment, likely most durable
  • Cons: Very expensive (~$6000), very difficult to find, hardware (filter, clamps, shutoff valve, etc.) likely sold separately.


Karbonius
  • Pros: Cheapest ($1800-2000), OE replica, uses all OE hardware and ducting
  • Cons: All hardware (filter, clamps, shutoff valve, etc.) has to be sourced separately. Some minor fitment issues.


Evolve
  • Pros: Includes alpha-n tune and all necessary hardware, designed to draw cold air without special ductwork, customer service. Available in both matte and gloss. Never heard of any fitment issues
  • Cons: Must use Evolve tune (unless you want to throw away money), does not use OE filter, cannot use CSL flap or ducting.

Those are the big 3. There are a couple others out there. Geoff Steele is popular in the UK, but I'm not really familiar with the specifics of their airbox. VAC is supposed to be awful



Wiring (for CSL DME Conversion)
You have two options: Either buy an OE CSL harness (pn: 12517833336) or modify the stock harness. You can buy an OE CSL harness for $600 - $1000 depending on the supplier; it requires minor modification to work properly with a manual car
