Spark plug and wire question?
 

Mazda RX 8 2004 Spark Plug Wire Set Set of 4 Spark Plugs | eBay will these fit a 2007 rx8? The part numbers are ZE81/RE7CL/RE9BT and it says that the plugs and wires are OEM. Maybe this is a stupid question? I just need them as soon as possible.

the only company that makes Rx8 spark plugs is NGK, so there is no aftermarket, you're just shopping on price.

the OE wire set is either sumitomo or Yazaki (i don't recall off the top), and the one in your ad looks like it might be NGK, which should be totally fine

Yeah, those are the correct parts.

Keep in mind that you can probably get them faster from your local auto parts store. Advance carries them for sure, not sure about Autozone or Pep Boys. They typically aren't in stock at the local store, but most stores can get them in either later the same day or early the next morning, with no shipping fee. (This is assuming that you are in the US)

I also tend to distrust buying maintenance parts from Ebay. Too many things can go wrong easily, and too many people have no idea what they are selling.

Denso also makes RX8 spark plugs. Mind you they are almost twice the price of the NGK though.

bought mine from rockauto but auto zone price matched the one I failed to buy online from rockauto,
16.97 or so
