I too have the HKS intake and I like it the only problem I see though is that it will be a little bit trickier to custom built a cold air box since it is bigger than the SLR around 8 " in diameter.
Stormy, what do you mean by "No spot for the Air Temperature senser on the HKS intake" mine has a tubing from the top of the HKS intake connected to where the original oem intake tubing was connected. I think there is a different in design from 2000 to 2001 model..
another problem is that I have to buy another filter every 10,000 miles, bummer..anyway I just put a shop vac prefilter on top of the hks filter to make it last longer...
