CaliGuy said:No one on this site can definitively tell you whether a certain modification can void your warranty. As far as the law is concerned a dealer cannot deny a warranty claim unless they can PROVE that your mod caused the issue at hand. This is NOT to say that some dealers will deny your claim anyway!
Please do NOT post any threads solely for the purpose of asking a warranty questions! These threads will be immediately deleted!
You may, however, post or start threads about your warranty experiences.

No aftermarket part or accessory that is properly installed on your vehicle will entirely void your original vehicle manufacturers warranty. It is the dealership's responsibility to prove that your modification directly caused or affected the failure you are trying to resolve.

I am going to take delivery of a FBP Si Sedan on 6/20. After having been on this site for a little over one month, I already have the modding bug. I have read countless threads about CAI, header, cat-back exhaust and Hondata reflash. The mods that I have read about or watched on videos have convinced me that I want to do these things once my car is properly broken in.
One of the pressing questions that I have had is about the warranty. Will these things void the warranty? I have researched a number of threads and have read about the Magnusson-Moss act. I did find a couple of sites that may help out. Notable are the ones from SEMA and the one from HondaCare warranty. On the HondaCare warranty page, scroll down to part IV section C: Note that the breakdown had to be caused specifically by the part in question.

Hope this helps out all who are looking to mod their cars and are concerned about the warranty being voided. As always, creating a relationship with the dealer service manager is probably the best way to keep your warranty.
I have a modded Infiniti G35 sedan. I have a Kinetix SSV racing intake manifold, Stillen CAI, Stillen cat back exhaust and HKS DLI II CD ignition. All were installed by the dealer and my warranty is still intact. When I got my car back from the dealer, I was so happy, that I bought the service manager and mechanic who did the work gift certificates to a very nice restaurant. A little kindness and appreciation goes a long way with the service people.
