it actually does the reverse. Blocking off the air from entering the motor from the bottom will help lower temps.

Small update. This splitter creates quite the high pressure area above it. It *should* do this, but I haven't actually had my magnehelic gauge out to test it. A few hundred miles of mountain drives tested it just fine.

I've never experienced this sort of bug carnage. It was horrific. I cleaned grasshopper guts out of my intercooler twice and there was still more to fish out when I got home. And never mind my lower lip's new yellow paint.

My two companions, both NAs with the R-package lip, did not have this problem. There were bug guts, but nothing like this. Maybe 20% as much.

This splitter really doesn't belong in the track forum, but it's nice to see visual evidence of it doing something right. My old homemade protective splitter never did anything quite like this.

I miss the NM mountains.

You need to find a dirt track shop and pick up some SS mesh radiator guard. I had to put it on my car to keep rocks and small animals out of the fins.
