*ECS Tuning Official Policy regarding Borg Warner KKK Turbocharger Warranty Claims*

To be eligible for warranty consideration, Borg Warner has stipulated that KKK turbochargers (or turbocharger kits) must be installed by a professional repair facility.

• Warranty claims must be accompanied by a receipt from a professional repair facility showing the date and vehicle mileage when the turbocharger was originally installed.
• An additional receipt from a professional repair facility must accompany the warranty claim indicating:
• Date and mileage at which the turbocharger failed
• Reasons for turbocharger failure
• Proposed repairs intended to correct the cause of the failure (if any)

Borg Warner will, at its discretion and with proper documentation, replace a turbocharger that has failed due to defects in materials and/or original workmanship. All associated labor charges for diagnosis and repair are the responsibility of the vehicle owner.

Let me know if you have any questions.

Jason, your entire business model is built on DIY, but this turbo is not warranted unless a professional shop installs it? Most of us are more quality focused on our own rides than a shop would be. Just saying. Thoughts?

Not our policy, that's directly from Borg Warner. Many manufactures actually have this policy in place when it comes to specific components.
