q45 throttle body
 

ok possible a dumb ass question, but what do they come on???

if you meen on what car! i think its from lexus or infinity not sure

<smacks forehead> Infinity's Q45.... hell you could have even Googled that.

There are a couple different revisions which vary in size from one to the next so if you have a specific one in mind be sure to get the inside diameter first.

i did a google, found a bunch for sale and how to mod to toyotas/nissans etc but not what it came off. my bad!

but now that you mention it, it is kindof obvious what car its on.

I've no idea what you were searching. "Q45" brings up nothing but Infinity hits. Well, at any rate you've got the answer.

yep time to raid pick and pull
