New NGK BUR7EQ / BUR9EQ Spark Plugs

RETed · 02-06-2013, 10:51 AM

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?

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.

FC Zach · 02-06-2013, 11:42 AM

That's if I get a newly manufactured set of course.

djmtsu · 02-06-2013, 04:07 PM

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.

Actually that would likely be the RX-8 Trailing plug

djmtsu · 02-06-2013, 06:02 PM

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 :-)

***TitaniumTT*** · 02-06-2013, 07:22 PM

I just bought two sets of BUR9EQ's and a set of whatever the colder plug for the 8 is..... lemme go check and see....

Pete_89T2 · 02-06-2013, 07:29 PM

I just ordered a set of NGK BUR7EQP/BUR9EQP's from Rockauto, I'll let you know what they look like when I get them.

***TitaniumTT*** · 02-06-2013, 07:45 PM

That's where I got mine from.... Oddly enough, they are the cheapest....

***TitaniumTT*** · 02-06-2013, 07:48 PM

RX8 ones look like RX8 plugs, BUR9EQ's look like they always have

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.

That's odd.

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....

Pete_89T2 · 02-09-2013, 01:13 PM

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.
