⚠️ BE AWARE: Not All Intercoolers Are Created Equal

Many less reputable sellers offer intercoolers that may look identical on the outside, but inside they use a cheap Tube & Fin core. These cores are typically 30–60% lighter, far less durable, and deliver only a fraction of the cooling performance of a true Bar & Plate intercooler.
