The same idea should work, the exact measurments might not be the same, you will just half to test fit, and build your own. pick up a 3" to 4" rubber reducer, and a 45*-4" elbow, and some 4" pvc, and try.

Here's my intake, quite easy to do, very simple. Cost me $66 out the door with a $10 off coupon from advance. It's 4 inch tubing with a 45 degree bend, I tried the 22.5 degree bend but the filter was to big and was hitting I believe the cruise control. I bought one 3.5 to 4in coupler, bought a 7/8's holesaw bit for IAT, came with the grommet. K&N filter 4x9 inch very pleased. I actually saw on the butt dyno you can def feel the difference. Supercharger screams like a baby. I also had a old 45 degree elbow and since my car is a 98gtp I already had the triangle duct where the guys use the roof flashing. I attatched the 45 degree bend on the inside of the fenderwell to duct cold air right to the tip of the filter.



Pic quality sucks, cell phone pic but you get the general idea.
