R45TX spark plugs

I went to autozone today to get a new set of plugs for my truck. Its got a small block 350 in it. They said that the stock AC Delco plugs (R45TX) are not available anymore. What the heck is up with that, and what do you guys use for plugs?

Re: R45TX spark plugs

I think the ones I put in my truck last week were R45CX or something crazy like that, they were just what NAPA had in stock and they seem to work pretty well so far.

Not sure what year your truck is so I didn't search - but AC's website is very helpful.

Re: R45TX spark plugs

Well yesterday I went back to autozone to pick up some other parts and I actually found a guy who new something about cars, yeah I know I couldn't believe it either. He gave me the R45TS plug. He said he didn't know what the R45TX was. They were quite a bit different. I went with the TS's and they worked, so I'm still confused on the difference.

I dont think there is a R45TX he must have thought it was.

That will help you find out what your plug is.
