BMW X5 X6 Intercooler (Charge Air Cooler) 17517809321 (2006-2014)

A smoke test or boost pressure test performed by a qualified mechanic is the most accurate diagnostic method. However, visual and physical signs often include a heavy coating of oily residue around the plastic end-tank seams (as PCV oil blow-by escapes through the crack alongside the air), or an audible hiss of air escaping when accelerating.

It is highly recommended. The rubber and rigid plastic charge pipes that connect the turbocharger to the intercooler, and the intercooler to the throttle body, are notorious for degrading and snapping off at the connection joints. Since you must disconnect them to replace the intercooler, inspecting or replacing them simultaneously is smart preventative maintenance.

If your current intercooler is leaking boost pressure or has heavily crushed fins, installing a new unit will restore "lost" horsepower, making the car feel significantly faster and more responsive. However, this is an OEM-spec replacement and will perform exactly like a brand-new factory unit; it is not an oversized aftermarket racing upgrade.
