STILLEN News: STILLEN Cold Air Intakes Receive A.R.B. Exemption

May 26, 2017




Street-legal status equates to being able to smog and register your car with ease while avoiding fix-it tickets and visits to the courts and/or the state referee. This becomes particularly important if you live in California or any of the 49 other States of America that subscribe to California’s style of stringent emissions requirements.


Developing performance products that achieve street-legal status involve a significant investment of research, development, time and money. To this end, STILLEN prides itself on the engineering time invested to garner measurable performance while maintaining compliance with the standards set forth by the Air Resources Board (A.R.B.). STILLEN employs a Nissan “CONSULT III” diagnostics computer to monitor and log vital data channels to ensure reliable and consistent performance. This means that STILLEN Intake Systems do not require ECU calibration and are a truly “Plug and Play” performance upgrade. No “check engine” lights and no idling issues.


Obtaining an Executive Order from the A.R.B. involves prototyping and testing to prove that our STILLEN Intake Systems do not affect the vehicle emissions control devices. Periodically, we resubmit and update our product listings with new products as well as updates to existing part numbers and additional qualifying vehicle applications. STILLEN’s most recent release included the highly anticipated VR30DDTT Intake System for twin turbocharged 2016+ Infiniti vehicles (p/n 402856, 402856DF).


STILLEN’s list of qualified products has also expanded its coverage under A.R.B. E.O. # D436-22.
