IMO
They do it so they can have another reason to void the warranty.
But yeah, when i checked the manual it said keep it under 4k rpm until break in is over.
I have some universal ones... just havent taken the engine bay apart yet.
I'm still researching water/meth ... only videos on YT I am finding are about q50/q60
thats a great deal
I had to go out of state to get the color i wanted, and I saved almost 5k from what the local dealer wanted to deliver the same car to me from out of state.
Oh.. cool didnt know that was an option.
I guess you can look on it to find the model and then try to get a manual for it online.
or search the model on YT to see if you can find a review that talks about how it works.
You talking about the one built into the windshield near the rear view mirror?
I wasnt aware it was for the driver, i thought it was only for frontal crash avoidance.
