I recently picked up an under carriage splash guard for a 2017 accord and I’m going to retro fit it onto Frankenstein. I don’t like road grime and water getting on my oil pan and engine and feel like they should have installed one from factory. Looks like they didn’t start making them until 2017. So that’s where I’m at now lol. It actually covers everything up until the exhaust tunnel so the engine is completely covered from road garbage.
Unless it's got a heat shield, you might want to rethink adding it. The exhaust will melt that plastic the first time it gets warm enough. It's either that, or add a heat shield to it.
