## Description

Genuine 8 pack NGK Iridium IX 4469 Spark Plug

Review: OEM quality. Cleared up a mis-fire. - My 2004 Titan started to develop a mis-fire yesterday. The last time I had this problem I took it to the dealer who said it was the plugs. I pulled the old plugs and they still looked new (NGK platinum). I got these delivered overnight and installed these new plugs. The truck fired up easily and with a smooth idle and no mis-fire. These saved me a trip to the dealer and probably a decent bill. The back plugs are a little difficult to get at but doable. All plugs were at the proper gap.
Review: Legit NGK - Weren’t counterfeit so that was a big plus
