Ebay user said using comptech parts does not void factory warranty (including headears, downpipe, etc..) Is this true?

 

It will not void the warranty unless the part can be proven to be the source of any problem.

For more info on the Magnuson-Moss Warranty Act, check out the following links. Note, this law does not specifically apply to cars, but to any warranty. Notice one of the links is off the Kingston Technology (memory manufacturer) website. Good explanation.

I believe it's under Title 15, Chapter 50:

I'm not a law student, just an engineer... so feel free to correct me if I'm wrong

 

well, in fact as long as it's not proven to be the direct cause of damage, any aftermarket mods won't void warranty. not just comptech on acura
