These can't be China. I bought New Old Stock Made in U.S.A. Green Stripe that is what the ad said and was recommended to me.

I bought these advertised as NOS http://rover.ebay.com/rover/1/711-5...0001&campid=5335822911&icep_item=152717023797

Then they are NOT TSX but TS....

Country/Region of Manufacture:

United States

I was just joking but check the plug itself when you get it, it'll be marked where it was made....

As said, the TSX plugs are the same but come pregapped at .060, TS (older version) is .045 gap.

Oh LOL. I will. I saw the new ones being made. The box has different graphics and the plug no longer has green stripes or any green. I may have to educate my mechanic because he told me that the NEW Delco plugs are made in USA. I don't think he knows made with Japanese parts in USA....

I have read the "new" delco copper plugs are made by Autolite........ 🤔

Today I learned why I killed so many HEI modules running a huge plug gap - despite having a huge coil, CD ignition box, and bright yellow spark plug wires.

Even the Bosch website says to gap my plugs at .045 So I guess that is the proper gap for R45TSX
