My filter is shielded and the open end is right up against the OE opening, so while driving, cold air flows in from the grill, through the opening and directly into the air filter.
There is also no way to do a true cold air system, as there is no way to mount a air filter in the bumper and really no way to route tubing up to the tb.
Jays intake provides much the same performance increase as mine but his uses a open element air filter and thus is prone to sucking in more hot air than mine. Easy fix though, just use a filter with a heat shield.
I would not say there was a large increase in performance but enough to be noticable. There was also really no increase in intake noise.
