Good point Aaron, that is very much a possibility.

However, since my commute is high speed highway where the secondaries are already open anyway, I'm hoping not to accumulate any buildups. But if I did more city driving, I'd be less inclined to pursue this type of mod.

Frankly, I'm more concerned about options towards filtering out or externally dumping the crankcase vents. Our intake manifolds get awfully nasty in a hurry anyway. wink
