Thanks for the info/point-of-view -- and don't worry about pissing on my Cheerios. I am kicking myself in the rear for spending money on that setup.jweltch said:I'm looking at the picture of that intake and thinking to myself: "Where is the >cold< air coming from?" and I can't think of an answer. The FIPK (and other single sided intakes) moves the filter directly into the path of cold air entering from the front of the truck (where they instruct you to remove the rubber flap - allowing the air to enter) with a heatshield in place in an attempt to insulate it from the engine/exhaust heat.
Both filters on that dual intake setup appear to be directly over the exhaust manifolds with no attempt at sheilding the heat away.
I don't want to be the one to piss in your Cheerios, and keep in mind that I have absolutely NO emperical evidence of this, but I doubt that you've gained any HP by using this, and believe that this is the reason for your loss of MPG. Have you tried to put the stock intake back on to see if the MPG improves?
I was actually going to stop tonight and buy a K&N drop in and put the stock housings back on. I have been thinking and thinking and the only way I know to "insulate" the air from engine heat is to have the filter in a box -- but then the thought of having the air coming through the grill and rammed into a filter sounds like it is "cold" air. So, I cannot decide on a K&N drop in, or a 360. The 360 setup looks as if the filter is down by the passenger side exhuast manifold or at least just above it....so I am wondering how that is "cold" air.
