Drilling honeycombs while on car?

[Torinate]

Hi there.

I really dont want to take the front bumper off the car...

Has anyone successfully removed the blocked honeycombs from just the air inlet area? I’m hoping to open up the closed honeycombs to allow more air in.

I’ve read dremels, drill them out, hot knife and soldering iron...

Anyone have pics or information on the best way to do this?

Don’t want to butcher it either...

Thanks for the help!

I did mine with a dremel and a small drill bit (1/4 " or smaller). I drilled a hole into the corners of each honeycomb and then slid the drill bit sideways between the holes. The drill bit heats up from drilling and slides thru the plastic like a hot knife thru butter.
