New NGK BUR7EQ / BUR9EQ Spark Plugs
This might be old news for some of you...
I never realized that NGK redesigned these plugs recently? It looks like there's a really minor difference in "reach" spec... Also, the center electrode matterial has been changed? The BIG difference is the with the "semi surface" tip to a regular, single electrode tip? These what Mazda recommends for the RX-8 now? -Ted

Haven't noticed a thing, I'm getting set of 7s soon. I'll check to see if they're any different from the last set.

Are you saying they look like this?
 That is a picture of the RX-8 spec Leading Plug (RE7C-L). If so, that's weird since their catalog shows the old (ie: 'normal') style plug.

If that is the case, NGK is using the same picture for both leading and trailing plugs.
I have a set of NGK RX-8 plugs in the garage, but I'm too lazy to go check :-)

It looks like the 9's haven't changed as much as the 7's? The reach spec has changed... Better for us? BTW, the "old" 7's and 9's are listed "N/A" from Summit. -Ted

I would trust things from the manufacturer more than from Summit, they could've messed a few things up when they copied and pasted the info.... I dunno, I'm kinda want to see a new one next to an old one....

I just got mine from rock auto yesterday. No changes from the old style, but the box had the same part # (5255 and 4764) as the old style too, so no changes expected.
