    Ricky, go to TFS's website, they have a chart for what plugs to get for their heads. Then just apply the logic for how many steps colder you want vs stock since I believe they give you the stock heat range.

    Autolite 3933's will fit but cover a broad range of NGK's plug heat ranges. I use the NGK R5671A-10 plugs in mine for 15# on pump gas.
