I've been looking at ECP radiators. I think someone on here said the fitment was all wrong. I know CSK loves his ECP. I have also looked at Northern Radiator and KKS Motorsports. I've heard a couple good things about both. Seems that lots of people have reviews on the 26", 22" seems a little harder to come by.
Check your local roundy round shops, that's where mine came from. The factory replacement hoses even work.
