No debris were on my TB. To me, it seems that if it releases fumes, it's over a long period of time and you'll probably be OK. A friend of mine told me he knows a guy with a turbo'd mustang that has partial PVC intake and hasn't had any trouble. But the CTA intake is better to go with just because it's smoother, and it's bigger helping to gain in mid/high rpms. Heat soak sucks though. If only street flight had made an intake for us.....
