View Full Version : AC Delco --> NGK equivelant

I was recommended the AC Delco MR43LTS Copper plug as an alternative to the IR plugs (expensive) in our 2010 LSV with Assault 325 (non catalytic).

I am trying to cross reference to NGK but I am getting 2 different models.

One is the TR5 and one is the BPR6EFS. Anyone know if these are the same, or which one is the correct one?

NGK TR5 is a direct cross to MR43LTS.
