Has Anyone Modified the Front Radiator Intakes?

Great info guys! Thanks!

I will be doing mine soon. Dunno about the lights, but I like what you were thinking.

Merry Christmas everyone!

I'll bet the ALMS / Rolex GT3's don't have A/C rads fitted and they probably don't have electrical cooling fans installed either. The screens are only there to protect them from flying debris.
The amount of air passing over the radiator surfaces @ 150mph is more than enough to cool the engine - running @ slower road speeds with many stop / start requirements will load up the cooling system far higher than on the track.

Day to day street driving and racing on a track are certainly different, and put different demands on the car. I see 180-210F from the on-board diagnostic tool in typical traffic with A/C on. Hot track days are a different story with temps hitting 240F when the car is fully heat soaked. Track driving generates a lot more heat so I think intake screens are a well tested and proven improvement.

If you're looking for real quality you can't go wrong with Zunsport grilles, I just I installed them on my 997, here's a thread about them: Zunsport Grilles - Rennlist Discussion Forums
