The magnuson-moss act can be tough when it relates to aftermarket car parts, especially if the warranty provided will replace the part for free under the written warranty. It (the act) was written to keep OEM companies from requiring customers to pay for their "part" and voiding a warranty if the customer decided they wanted to buy another companies "part" that complied with their OEM's standards.

BMW warranties their OEM intercooler and will replace it free of charge while the car is under its warranty period. If you choose to install another companies intercooler and request warranty repair on "something" that is attached to the intercooler (like everything downstream of the intercooler), BMW has the right to deny warranty repair but they must demonstrate, and document in writing, that the other companies intercooler caused the problem to the part(s) you are trying to get replaced under warranty.

Also, the FTC has validated the right to install "aftermarket" parts, including specialty parts, on a vehicle:

But BMW can still void your warranty, or refuse service/parts free of charge under warranty, if they demonstrate and document that the aftermarket part was the cause of the damaged part(s) you are attempting to get repaired under warranty.

I'm no lawyer and I'm not saying that the Wagner Intercooler doesn't comply with BMW's OEM standards but the magnuson-moss act isn't a 100% safety blanket.

Just trying to help here, these things can get tricky
