Went to autozone today and asked for the NGK tr-55's everyone suggested I get, and the guy gave me NGK tr-5's claiming they are the same, I don't agree, but I figured someone on here will know for sure, are tr-5's the same as tr-55's

I'm not sure the difference...but there is definitely both kinds... I always get the TR-55 from Napa.

Here is a thread on this:

NGK TR 5 or TR 55's?

From my understanding the only difference is the heat range, so no they aren't the same.

the reach of the tr5 is longer and it has a gasket you have to use the tr5 with dart heads and they come gapped .039 instead of .06 you need stock

No, you want NGK part number 3951 for the 55's.

I was not aware that a gasket style plug was needed for dart heads. (not saying your wrong, I never thought of that) Is this correct? If so I guess I've been running the wrong plugs. I've kept tr55 in mine. I never looked at the heads to see if they were angle sealed or washer.

They say the newer darts can run either but i believe they where originally made for gasket style and a 3/4 plug so you can have a wider variety of plug to pick and choose your heat ranges... im still trying to fig out what i want to run in my darts lol
