Nice product and looks

Bought it in advance for a planned 2.5"intercooler" sys& PROGRSSIVE N.O.S SYSTEM . I'm going to use it to mount the 2 nitrous nozzles. As it's aluminum and can be drilled and taped.

Fits great and does what it says

If you do a full stack intercooler you'll need this. With my particular set up it works great! I am running a North Star TB, on the ****** the TB mounts to. They rotated it slightly, with the n* the throttle cable bracket sticks up now and pokes my goods insulation. I fixed it by kissing the bracket with a cut off wheel. If I were running the stock TB I don't thing this would be a problem. But the n* doesn't need the rotation. Also it's got this crinkle satin black coating rather than gloss black shown as the pic.

Needed more hood clearance on a intercooled Gen V

Worked great in getting me a little more clearance from the throttle body and hood

Another Good solution from ZZP

Adapter I received was more of a textured paint and more matte than glossy, I don't mind just knows its different than picture. This part installs well and came with good hardware. No problems. Works great
