I just wanted to check, do you know what the warranty issues are if a customer installs a product like your cold air intake onto a vehicle under manufacturers warranty. I just didn't want to do anything to invalidate my warranty with Holden.

Technically any aftermarket (non factory) upgrade can void warranty. However from experience, our cold air intake kits for the Cruze have never been an issue. In saying this though, if your vehicle is still being serviced by Holden, you can always revert your car back to standard prior to taking your vehicle in to Holden for service, or in the event of a warranty related claim.
