The consistent finish and fitment of Pro Series Intake Manifolds is the result of care taken by the foundry to produce high-quality parts as demanded by Skunk2. Clone manifolds can be identified by their irregular casting marks near their badges (2), unpredictable finishes and blemishes, and slightly square-shaped plenums (1). Genuine Skunk2 Pro Series Intake Manifolds can also be identified by their acid-etched, stainless steel nameplates. Notice the slightly rounded corners and shiny appearance when compared to the clone. Also notice the make-shift, trimmed corners on the clone manifold’s Pro Series nameplate. Once you know what to look for, spotting the clones, and then avoiding them, is easy.
