I removed the R45TS plugs from my ZZ4. These are not the plugs specified on the Sallee Chevrolet site. Sallee says MR43LTS come standard and FR5LS or Rapid Fire #5s can be used. My question is the plugs I removed have a short thread and bevelled seal. I don't think they are orignal. The Plugs called for by Sallee have a longer reach and a gasket seal. The FR5LS plugs look like they will extend into the combustion chamber and I'm worried something might hit. Is this mormal? The Old plugs were working ok, but they are not suppose to be the correct plug. Also this ZZ4 was purchased in 2000.
