your running stock filter set up vs the K$N system..did you try the K$N element only vs the K$N system??. Smple volume of air will cause some cooling effect..give me a graph of the two K$N systems vs each other and then you get my attention..also I'm curious and not knowing...do the stock systems run a silencer style pc like the fox bodies did?, if so was it intact duing the stock run?..and if so was it intact during the K$N system run..though it likely was not in or unable to be used. You may be correct that the K$N system does indeed have SOME effect over the stock system..but I would like to see the above mentioned stest prior to making a decision. Also I would need to see a dyno graph to be convinced that the temp drop if does exist in above test..does affect HP numbers. I do know BBK style Mac style CAI systems are appearance only modifications..I would be very interested to see the K$N system work effectively..hell I'd likely be interested in the install myself.
