I don't recall the name of the computer we used to scan, but it is a quality scanner that is used at my brother'* shop and serves reliably on the multitude of autos it has been used on.
As far as conditions, it was relatively chilly this past weekend, BUT, someone had made the contention that the intake was knocking and vibrating, therefore causing the KR. Regardless of the temperature, this portion of the issue is proven untrue as long as the intake is mounted correctly. Someone else commented on "heat soak". But again, unless you are running a heat shield wrap the way WillWren mentioned in another posting, all your parts will get hot in the summer regardless of whether it is rubber or metal or whatever. So if you do get KR in the summer, the sole cause is not the material your intake is made out of, but more likely the cumulative effect of ambient air temperature, the temperature at which your engine components operate and/or how quickly you can dissipate the heat your engine and/or components generate. You would generate tons more performance if you were to say vent your engine bay with fresh air compared to fiddling around with what your silly intake pipe is made out of. Its primary function is to suck in fresh air and somehow we are missing this point here. The air traveling through a simple tube is not going to heat up anywhere nearly as much as it will compared to what happens when the air is compressed in the SC regardless of material. (We are talking about a lot of friction in the SC compressor)
So what issue the other person had with this intake is unknown. This may come down to the age old question - is it the component or the user with the problems? or in gearhead terms - is the problem a loose nut in the wheel or the loose nut sitting behind the wheel?
