Just a quick question: I'm thinking of installing the Ingen intake and Apexi N1 Muffler on my '03 P5, will this affect my warranty? Thanks in advance for any help.

 

Use the search function at the top of the page, this has been covered before.

Exhaust shouldn't matter at all.

Intake shouldn't matter either, unless the cause of any problem in the future can be directly linked to the installation of the intake.
Just take it off if you have any problems, easy 5 minutes.

 

i would say that it shouldn't viod your warrenty except the it will void your exhaust and your intake warrenty but that doesnt matter. to be on the safe side with the intake if yiou have engine problems take out the intke and put the stock one in before sevice... you know how dealerships are if the can pin it on something else to save them money they will even if its just an excuse.
