It isn't just Honda vehicles that are so picky about the parts you use. I know many of you are trying to save money by purchasing aftermarket parts, but to be honest, they don't always work out. In some cases they even cause more problems than they fix.
If you do go aftermarket, get the best quality you can afford; you'll thank yourself later. Putting cheap aftermarket parts on your vehicle is like playing Russian roulette. You can really mess things up and make the problem you were trying to fix worse in some cases.
I'm not saying all aftermarket parts are bad; in fact, some of them are the OE (original equipment) supplier, so what you're getting is an OE part without the dealer markup. With a little research, you might be able to find the original supplier for your vehicle’s parts. If so, this would be your best aftermarket option. Some aftermarket parts, however, are just cheap knockoffs of the originals. With these, you often get in the door cheap, but it's not long until they fail and you're right back where you started. Remember, your repair might only be as good as the parts you use, so be sure to use the best parts you can get your hands on, aftermarket or otherwise.
