The NGK Iridium IX LTR6IX is a single OE-replacement spark plug with a fine iridium center electrode and a tapered ground electrode. It is a direct-fit plug for many Ford, Mazda and other engines that specify the LTR6IX heat range, so it suits drivers replacing worn plugs or upgrading from standard nickel plugs. Against platinum and copper plugs it holds its gap longer and takes less voltage to fire, though it is not a gimmick plug and offers no gain over a fresh stock plug of the same spec. Buyers should confirm the LTR6IX part number against their engine before ordering, since heat range and thread length must match.
