I was messing arround online on the search of a decent but cheap CAI for my Reno because my old intake cracked. (I made a short ram using pvc pipe, and It worked really well but didnt have a way to secure it to the car.) So I came across one that looked like it would work. it is for the Eclipse 01-05 gs rs link:
eBay Motors: 00-05 Eclipse GS RS 4 CYL Cold Air Intake 01 02 03 04 (item 180267452776 end time Jul-24-08 22:56:15 PDT)
With very little modification i got the intake to fit! Here are the things that had to be done in order for it work:
-Cut away the insert for the crank case breather hose on the shorter pipe and with a dremel make the hole bigger to where the sensor can fit.(you will have to buy a little air filter for the crank case brether, i got it for $10).
-Modify the aluminum bracket provided to hold, secure the intake.
-Cut the end of the longer pipe, so that it become straight so you can fit the air filter.I used aK&N cone filter instead of the crappy one they sent.
I liked the CAI better than the short ram I had, felt an increased acc.
So for about $45.00 you can have a very decent CAI system!
when I get a chance I`ll post pics.
