New NGK plugs not stamped on ring

Gents,

I went searching for new plugs today. All the NGKs I've ever used have something stamped on the ring, just above the threaded portion, such as "ASSEMBLED IN U.S.A. FROM JAPANESE PARTS" or "/ / / / JAPAN / / / /". All the used BKR6EIX-11s I pulled out of my Sequoia had the stampings. I went to almost all the O'Reilly, Advance, and Autozones nearby and all the rings are blank. Is that the new normal?

Thanks,

 

I don't know but as long as you're buying plugs from a legit retailer they should be fine. Don't buy any from Amazon or eBay.

 

I just bought a set of NGK 4687 IFR6B-K from RockAuto. I'll let you know when they get here. What I do know it that for this particular plug, O'Reilly was more than twice the price compared to RA. Worth the wait.

 

I just got NGKs shipped from RA, no stamping on the ring either.

 

Budget cuts

 

As promised, I just got my new plugs from RA. Not sure what's up. I sure feel better about them having "JAPAN" stamped on them, which they do.

 

You like them better than the BKR6EYA the OM calls for ?
Considering trying the NGK BKR6EGP G-Power Platinum's next plug change.

 

I'll let you know after I install them at the 100K service.
