Very slightly tapered.

i have a spectre one..trying to find a skinny one..i got a 10 in cone,think its to big..

I cant find a k & n filter ..im on website looking for 1 ..

I didn't have to cut any brackets out of the way, I did have to remove the front bumper cover though. Pass the tube through, then put the filter on, then put the bumper cover back on.

yikes..hmmm don't want to really do that..

How did you hold down the ECM?

The kit I bought came with a bracket to hold the PCM down. You could also take a piece of thin sheet metal or whatever you have around, cut it to be about 2" wide by 5" tall. Bend to 90* at the 1" mark, drill a hole in the middle of the first 1" big enough for a self tapping screw. Place next to the PCM, then bend it 90* again over the PCM and secure with your self tapping screw at the bottom. You could also paint the metal, maybe with some underbody coating. Also, removing the bumper cover isn't bad. Take out your splash guards on both front wheel wells, I believe there is a single nut for each side of the bumper cover that when loosened should allow you to slide the bumper cover forward and out.

well I worked in a body shops for 15+ years but I don't like doing my own stuff for that anymore lol...hot rodding is different.
