CT4-V Blackwing Carbon Fiber Airbox W Filter Upgrade w

 carbon fiber airbox lid system for the CT4-V Blackwing is a work of art. And it also performs! Internally, this revolutionary new airbox design functions in a proprietary manner that increases airflow and boost, without the ECM being aware of the changes. If you bolt this intake to your completely stock CT4-V Blackwing, you will instantly gain 30 to 50 peak whp. Even more impressive are the 70 plus whp gains you’ll have near redline!

These performance improvements take place with no other changes, and no tuning required. Idle, drivability and fuel economy will all remain the same as stock, as long as you stay out of the boost. This intake system is safe for any fuel octane from 91 on up. If you’re currently running the JB4, you will need to work with us for some custom settings at the time you install the carbon fiber intake.  In most cases, you will start with your current JB4 settings, then reduce all numbers in the Fuel Bias column by 10%.  In order to check and/or edit the fuel bias settings, click on SETTINGS, then USER ADJUSTMENT.

Coupled with custom tuning, you can expect to see gains of approximately 100 whp on 93-octane. colder spark plugs with smaller gaps are required at this level, and when add on with downpipes, you can make even more power!
