A cold air intake for a truck that has an intercooler in the turbo system to cool the air. What?
Take a look at the video Project Farm did on YouTube about engine filters and how the K&N did. (Walk.)
Did you disconnect with the engine off? If so, you should have received a message asking if you'd disconnected, and of course, you need to select YES.
Rehitch and go through that sequence.
I've had it on one day, and I'm not planning on sleeping in it. For ventilation, the front slider might be fine since there's a positive-pressure air vent on top. If more ventilation were needed, you could rig up a strap to keep a side door almost closed since they want to be up when unlatched.
I can't swallow the idea that an octane change will get rid of any engine noise. Pre-detonation yes, but our trucks won't have that because of the ECU.
Now, you believe it, so that's okay.

I'm trying to do this relocation. I've two nuts removed from the third brake light and can't find a third, like in the Tundra video.
The light doesn't want to budge. Is there a third, or how did you get yours out?
Thanks.
