Well that all depends. If the JRSC causes damage to your engine, then, no, Honda probably won't cover you. But if you damage the JRSC, Jackson Racing might. Like anything else aftermarket though, it works the same way. If you put springs or coilovers and something brakes, same ol' song and dance. Body kit and something flies up underneat the front lip and into the radiator ... probably won't be covered there either because the gap between the radiator and lip or bumber is larger; using a Spoon magnetic oil drain plug, let's say the magnet detaches and janks up your engine ... sorry again; spark plugs not recommended for your car, spark plug wires, non-honda oil cap, bla bla bla, the list goes on and on, hell, I could've broken my leg today when I nearly stepped in a big hole, oh well. On the other hand, it is your car, and that's up to you how you want to upgrade it, after all, that's what makes it fun, it's the "custom" in customize.
