I am getting an IceBox soon for my CL. Price is $240 shipped. Compech Dyno's show an increase of 13hp & 8 ft-lbs over stock, more than even the AEM.

"...a stock 2003 CL-S 6 Speed and it was 221WHP and 207.7 WTQ. With the Ice Box installed it is 234WHP and 215.7 WTQ."

I could only find IceBox dyno graphs for the Integra and Civic. I wanted to keep a conservative look, so the icebox was my choice... extra bonus that it makes more power than all other intakes!
