That intercooler is all aluminum, it's the basis for the GH intercooler. Good stock repacment. But The GH core is about 70% thicker (2.0" core vs 1.25" core), flow benched and formed inlet and outlets, drain plugs and bungs, etc. GH cooler is made by CSF. CSF is one of the biggest names in aftermarket and OEM heat exchangers, radiators, intercoolers, etc.
Also that stock CSF cooler is available for probably $160 so keep looking if you want a better price. But no, this isn't the same level as the GH IC, I've had both.
