I need some spark plugs tonight and no one has the TR55 in stock. What are some comparable plugs to these and where would i find them?

this is for a n/a 383

thanks

 

I had the Bosh Platinum 4 in my car. I swear by them. I did remove them to try the TR55's Good plugs too..

My car is normally aspirated.. Get the Bosh Platinum 4's and you can forget about them...the just work good. Mine were working great when I took them off. If anything they will last a long time on a N/A engine like mine.


when my TR55/s wear out I will just put the Bosh back on... I saved them. I only had like 30k miles on them though.

Any parts store can cross reference plugs for you. I run Champions in mine. I'm not sure of the model but they were corss referenced with the NGK's a couple of years ago. I change them every year. It is a pain but regular plugs don't last for 50,000 miles the way I drive. Of course I don't use plats as the pucks tend to fall off.
