Ok, first off take a look at this
K&N Cold Air Intakes page. If you'll notice they make the typhoon for the XRS and the 2004 XR. Now the three cars look like the air intake manifold is in the exact same place with the exact same clearance all around. I wouldn't know though since I don't have access to all three cars at once.
Now you might disregard the next two suggestions but try looking on e-Bay or at Autozone. With e-Bay the intakes are clearly marked. With Autozone you just need the diameter or a silicone transition and maybe some extension tubing and bracket.
Now my last suggestion is a company called
Fujita. Apparently it's a very well known company but not inexpensive at all.
Well happy hunting, hope you find what you're looking for.
