Mine's coming out ASAP thanks to busted plastic. Here are the details. Nismo: Confirmed 16% greater cooling capacity, bolts in. 2" Koyo: 20-30% better, Heli-arc welded, cores are NOCOLOK-brazed (no epoxy). Needs new bracket. custom Howe: Nobody sells these, but they are a popular choice? Needs new bracket. 2.25" Z1 (also Howe): billet CNC machined neck, bolts in but not a popular choice stock Maxima: I heard this was an option.
I need one that will plug in easy and keep the fan shroud. Any other recommendations?
