a friend of mine and I have started a Stunteam as a program to reach out to students. I own a Seville STS 4.6L NS, and one of the kids suggested "supping" it up for Performance Driving. Several thoughts that came to mind for that kind of driving were A.) Synthetic Oils (I've seen strings on this, but none of them really addresses "drag-racing"/performance driving) because the engine will be naturally running hotter. B.) NOS kits C.) Cold air intakes (though I cant seem to find any or K and N Filters for the newer caddy engines). Any and all thoughts welcome!!
