These NGK iridium-tipped spark plugs are stock heat range. They come pre-gapped to .031", which is fine for a stock-power car.
Note! Use extreme caution when gapping an iridium-electrode spark plug. The electrode is extremely thin and brittle and will break if you apply too much sideways pressure.
Set of four spark plugs.
Fits all 2002-2005 Subaru WRX.
