12. Continued

This is what was removed from the Snorkel Connector Hose to fit correctly inside of the TRD Air Flow Accelerator Hose. I recommend cutting off less than you think you need, and fitting before removing off too much. A total of two cuts were made with a NEW razor knife.

SNORKEL ONLY: If attaching an aftermarket Snorkel to the TRD Air Flow Accelerator Hose use the 5" Stainless Hose Clamp (purchased separately) to secure the TRD Air Flow Accelerator Hose to the TRD Lower Air Box.

Mine flashed a Check Engine Light after a few hundred miles and started rough idling and stalling. Took it to Toyota. They reset the code and everything was fine. They told me that the computer has to Learn the new air mixture, but once the code is reset there are no issues. Clicked 5k miles on the odometer today.
