I don't mean to sound like an ass, but read your warranty booklet. I say that because I, too, was wondering things I could do that would void the warranty. The booklet is pretty easy to follow and lays things out for the most part.
The basics of what I got from it are....Honda doesn't mind if you use non-Honda parts or get it done by non-Honda people, so long as the following is met:
1. Replacement parts of are equal or better quality of craftsmanship as OEM.
2. Repairs/mods are done properly.
3. Nothing was abused or misused.
4. The parts were designed specifically for your year and model vehicle.
If you make a mod that is not in compliance with the above, it does not void your entire warranty. The dealer will refuse warranty work if it can be shown that your modification caused the failure.
For example, if you put in reverse EL guages, and your cluster fails due to electrical malfunction, they may void your warranty. However if your wheels all fall off, that's still covered.
Bear in mind I do NOT work for Honda, and what I've said here is merely
my interpretation of the warranty. Your best bet is to call the dealer or call their zone office and ask them directly.
I do know for a fact that some dealers are more liberal with warranty work than others.....it's really up to your dealer. If you disagree with the dealer, though, that's where the zone office comes in.
