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 |
