Those marroons at total seal even after me saying 29 times I had a 4 cylinder -- sent me enough rings for a V8 -- the bad news is they charged me for them too.
SO here's the deal $150 shipped to you
4" standard gapless 1st and 2nd
For some reason they only do the 4inch bore sets for 8 cylinders,you would be better to keep them as spares surely
