Spark Plugs?
 

Has anyone any info as to whether E3 spark plugs can/should be used in an RX-8?

Does E3 even make a plug for the RX-8? Even if they do, unless you've got some specific reason otherwise (turbo, racing, whatever) stick to the OEM plugs.

You can get the OEM's from Advanced Auto Parts for about $60 using their coupon codes and picking up in store too!

Ok, cool.

What about these NGK Iridiums?: RockAuto Parts Catalog

:fingersx:

Link doesn't work here.

OEM Plugs are the NGK Iridiums, at least in Germany.

As far as I know, RE7C-Ls are for the American/world market and RE8C-L are for Germany and other Countries with roads without speed limits because they can take more heat. Trailings are the same, just don't have the number here at the moment.
