undertray removal
 

hope someone can help is it best to remove front undertray to get better air flow over tmic and engine cooling or is it best left on

Its best left on, removing it will increase under bonnet temps.

Long history of discussion for this one - have a search for previous threads as I seem to remember there was never a set conclusion.

I keep mine on as I take my car to the track and it's good for protecting the bottom of the car when I run out of talent and end up in a gravel trap!
