Engine bay paint code for the Spirit R titanium
 

Anyone know the color code for the engine bay color for titanium grey as it seems is different color compare to body color?

It should be the same color as the rest of the body, they spray the entire chassis in one go. The part under the hood does not get the complete paint process so that may explain the color difference.

engine bay doesn't get the clear top coat

That's a bingo.
