I don't know much about CAI, but I keep hearing that they simply let more trash in. How much of this is true with the Volant? Also, how hard is it to re-oil the filter?
Since this thing has two inlets (one in the front, and one in the stock side location), could I put a deckplate in replace of the front location? I would love to do this so that I could later do the internal snorkel mod on the side outlet, and find a way to block it from noise when I don't need it.
If this thing really does save this much gas, and filter the same, then I'm getting it. The way I figure it, it'll actually pay for itself in less than a year with my driving.
The only thing I'd be worried about is if you drive in really dusty conditions frequently. The filter element is obviously going to filter worse than a stock filter, with the idea being that the oil will catch the fine dust, but there have been studies that prove this isn't the case. This should be obvious, since the whole purpose of an aftermarket intake is to increase air flow and reduce flow restriction.
The nice thing about the Volant is that it puts the cone element filter inside an airbox which is insulated to keep the radiant and convective engine heat from heating the intake air. It also uses the factory location in the fender from which to pull cool air. Generally, this means cleaner air. Quick blasts through a dust cloud won't make it into the fender or airbox, and even if a relevant amount does, the filter will do its job.
As for the hole in the front of the Volant box, this small hole points forward (toward the back of the passenger headlamp). I've done alot of looking in this area and have determined that a decent (not large) amount of cool air probably flows in this area. Again, unless you are driving in very dusty conditions, I don't think this is a concern. A simple way to know for sure, is to simply put some duct tape over the hole, then you know for sure that air is being pulled from the fender.
Even if you do drive in dusty conditions, but still wish to have the intake, many companies make a "sock" to put over the cone element. This sock will be much more restictive than the filter, but will filter out fine dust. The advantage of the intake system now being its flow dynamics vs. stock, and not flow restriction.
As for re-oiling, it doesn't look hard. Just unscrew the lid from the top of the box, undo the filter element and oil then put it back. Seems like a 5 minute job...
