Anyone know the measurement stock MAF position to the throttle body? I want to change mine, which is about 12 inches, closer to the factory distance. Thanks for your help.

I've sen them butted up against each other and 500mm apart.

The difference in performance can't be much as even Toyota/Lexus had differing dimensions between the different vehicles the engines were fitted to.

Zuffen , these vehicles must have slightly different MAF maps then. The small differences in MAF response introduced by different MAF to TB distance are easily addressed by the fuel trims, I believe. So, in short, there's no need to worry as long as the engine is ok. But there's nothing bad about making things perfect either.
