I don't think so. If you look at the stock airbox for both the SVT and non-SVT, the air inlet is rather small compared to the rest of the box. IIRC the hole is only a couple inches in diameter at the most. Its almost literaly the definition of a bottleneck. I would think that having the K&N or similar filter surrounded by a box is still allowing more CFMs than that small inlet. Plus, I would think that having temps closer to ambient would negate any CFM restriction created by the box. Call it a compromise.

If you're worried about enough air getting to the filter, do what Demon did and run some kind or hose from the fender up to the filter.
