Thread: Q45 throttle bodys

I'm in search of a Q45 throttle body at my local scrap yards. The general question I'm getting is what year, and if it has traction control. So what year cars should I be pulling it from, and has it changed from 1990-1996? I'm assumming I'm looking for something between 90-94 though just because of the whole obd2 thing... but who knows for sure?

90-94 without the aluminum elbow on it

What about the traction control, does that matter with or without?

Without iirc

ok thanks for all the help dave.

NP. I'm pretty sure the one with the TC looks like a tumor growing out the TB

Some people are saying the Q45 is 85mm some others are saying 90mm which one is it?

One is I.D and the other is O.D. Saying it's 90mm makes it sound more impressive and easier to sell.


In reality, the Q45 TB is 82mm ID after the throttle plate. No guessing here, measured with dial caliper.

I can see why they say it's 90mm I 'm definitely less intimidated by it now lol. Thank you bro.
