having a conversation with another Jeep friend, I noticed he didnt have the plastic engine cover installled on his penstar, we went back and forth about wether is just for show or it directs air flow under the hood for cooling.

2018 yes, 2020 JT no
 
I always thought jeep intended it as a dust cover, but that is just a guess.

A few people I know trashed theirs because they thought it trapped heat. Logically seems to me that it would keep heat in, but I have never tested it.

Coincidentally took mine off my JK for the first time last week at 120K miles.

My throttle body position sensor plug is cracked and I have it electrical taped up. Was thinking ditching the cover might keep the tape from melting as much, hah.
