Hi! Im installing grille lights on my s550 and i wanted to see if there is a way to cut out the false/closed honeycombs in the stock grille to make room for light. Anyone know how to do this job clean and easy?

I used a small router, used it on the back of the grill. a 1" bit.
You need to cut the back excess plastic... It's messy, but at the end all holes will be open... I'm trying to loate my post of few months back.....

Look at the backside of the grille. You will see a line around each part where the honeycomb is. Used a dremel with a cut-off wheel and follow the line.

Wish I could hear more about this. Maybe there is another thread?
Sounds like with a router you just cut deep enough to take the blanking off the back. With a dremel its time consuming and easy to screw it up?

I also went the way of using a router with a 1" bit. Set it to remove just under 1/4" of material off to open up the honeycombs. This is a messy process as you have plastic shavings everywhere from the router. However, makes for a very clean look once it's all done. There will be some very small shavings attached that I used an X-Acto knife to clean up. Here's the end result before reinstallation.

I used a soldering iron/gun. It had a flat blade adapter that resulted in a nice clean job.

Does anyone know why some of the grill is closed off?
I think with open grill, engine will take longer to heat up. Particularly when its cold outside. Open grill also increases drag.

Adjustable / active grill would be better.

I can speak for the turbo; air flow efficiency. Working with the Active Grill Shutters which close at higher speeds forcing more air around the car rather than through it, drag is reduced. Since I live from stop light to stop light I opted for maximum cooling by deleting the Active Grill Shutters and opening up every factory blocked honeycomb.

You guys saw the pictures of the test mustangs, the ones with nose all covered...see how little an area is open for air on those. Of course we don't know what engine is in there.

stop light to stop light, with an open grill, the engine could take a longer time to get fully hot. If you are on the gas during that time, its not good for the engine. And if you aren't on the gas, then heat shouldn't be a problem.

Think "possible hood flutter" at highway speeds. I opened the triangle at the triangular cold air intake [Velossa inserted from the back] only. No flutter.

Not everyone experiences [or admits they have] hood flutter, but you might. Use of any of the aftermarket 'open grilles' can also result in this issue.
