The 930 intercooler has complex shape end tanks including the use of O-ring seals as opposed to rubber hose unions. There are also a number of Mounting brackets, auxillary pluming take off, and sensor bosses. The end tank structure must also be sturdy enough to accept engine vibration since the intercooler is mounted directly onto the engine, and fatigue cracks would not be acceptable. Quality is critical for correct fitment as can be seen in a recent thread.

The intercoolers you see marketed for the japanese imports have very simple end tanks, most being made from folded sheet metal. They have no auxuillary pluming take-offs or bosses. Some are marketed as universal fit. The customer is expected to drill holes in the rad panel for mounting as well as cutting large holes in the rad panel for the inlet and outlet hoses to pass through. Nothing complex in nature at all besides making the installation look professional. Plumbing is done with aluminum or rubber/silicone elbows and hose clamps. Bolt-in but requires tin snips etc. depending on application.

Professionally built kits for Japanese cars sold by the like of HKS etc are also expensive, but well engineered too.
