Okay, since last week we had such a good puzzler, we are gonna ask for more synonyms this week. 

So, the puzzler is, what other words can you all come up with that are automotive in nature, but have another meaning which are synonymous?

So examples are tire and exhaust. 

Another example are the words block and plug. 

And another one, bolt and dash. 

So just like last week, what automotive words have secondary meanings that are synonyms?

Good luck.
