Yeah, so I'm a newb...whats a MAF?

Used in a sentence, "My CAI came with an attached 87mm MAF."

Thanks for the help.

 

Mass Air Flow sensor.

 

What's its purpose? What's it do?

 

"Mass Air Flow" is the actual housing & usually comes w/ sensor inside your CAI housing that leads to the air filter - to measure the amount of air coming in to the engine - the sensor records this and relays it to the computer and then to the engine to help determine things like air to fuel ratio, etc.... - that the Diablo or XCaliber or some other tuner is required on the 05 s is to optimize this process...

 

Ahh cool, thanks for the explanation...=)
