My tendency is to delete both for better airflow to the intercoolers, but I do like the extra light they provide in the fog/snow. Major dilemma!

That is a neat idea just using screen behind the driving light holes, kind of ghetto, but functional.

or just replace the light.

I'm a lazy b?strd.

That "scientific test" was for ONE boosted run with fog in place and ONE boosted run with fog removed (unless i just missed the part of him boosting consecutive runs).

When evaluating the effectiveness of any intercooler or intercooler "upgrades", you must take into account multiple consecutive boosted runs.

I have data logged and helped data log multiple passes on intercooled and non-intercooled cars. What i have found is that IAT's WILL go up with each consecutive boosted pass. This indicates you need to keep your intercooler operating at close to peak effiency for not one, or two passes, but 5 or 6. Keeping obstructions away from the front of the intercooler, or intercoolers (or even getting an intercooler if you don't have one, lol) will help.

Also, Letting your car sit in the afternoon sun or at a stoplight to "heat soak" the intercoolers is nothing like throwing boosted air through it.

Of course you can't believe everything on the internet, so take my advice with a grain of salt, as you should that "scientific test".

Sorry, i am now off my soap box ;)

driving the passes in bliding snow.

Sure looks good!
