Default Clear powdercoating on intake

Earlier, I asked about stripping powdercoating off an NOS lt-1 intake because it looked like silver paint. I tried a section at the back and found out that it was clear powdercoating only. I really don't like the look of it, because like I said, it looks like silver paint. Is there any advantage to leaving it on there? Will it turn yellow like clearcoat will on an engine? Thanks a lot.

Not if its a good quality powdercoat. They bake the stuff at 400F+, so a couple hundred degrees of engine heat isn't going to bother it.

Thank you. I'm still debating whether I should strip it or not.

But beware if you have exhaust crossover ports on your intake manifold.
Exhaust gases temperature is much hotter than 400°F and could slightly bake your paint near these ports,
or at least yellow it...
