Black HOV Bought Used Posted June 30, 2005 Report Share Posted June 30, 2005 I am looking to change out spark plugs during header installation in a couple of months. Which plugs are recommended for a normally asperated engine? Has anyone else heard of the E3 Spark Plug? JEGs has them. I have used them in my small engines when the champions failed and they really make a difference. Does anyone have any information on how well they do in the VHO 6.0? Are the stock plugs worth keeping? I intend to change out the wires too. Most likely will upgrade to the MSD 8.5s. Any other suggestions out there?
