I was gonna hit up the Auto Parts stores after work. TGIF. I hate ordering something that I can get locally. Go crazy waiting! As far as I can tell, it's not specific to the Redline, just a filter that has the same attachment point, diameter, and fits in the airbox properly. I tried to look up the KN0008 number and it's not listed at K&N, the all have numbers like 2115, 2165, etc.
That is what I have (E-1009) and it is a perfect it. It is not the easiest thing to get in. The OEM is not attached to the lid, where K&N is clamped. This giving much less room to get it in. There is another thread that explains the easiest way to get it in and out. Main things I remember is to pull the heat shield back on the radiator hose that goes over the airbox lid and two sets of hands is a great help one putting the filter back in and one squeezing the radiator hose flat. Take the screws completely out of the lid so you don't punch a hole in the hose as well.
