Carburetor is a car part, but prosecutable is not

My wife and I like to listen to PuzzleMaster Will Shortz.on NPR.

This week’s challenge is from one of my favorite puzzle makers Merl Reagle:

Take the word carburetor, add two letters and rearrange the result to name another car part. And the answer is one word. What car part is it?

It took 1 minute to write a program to solve this, 6 second to run it, and it’s pretty clear that “prosecutable” is not a car part

If you learn the answer from this post, to be fair, please do not submit your answer to NPR.
