## Description

Genuine 8 pack NGK Iridium IX 6509 Spark Plug

Review: Good spark plugs and for a good price. Also grab a gauge to properly gap! - Working well so far. Product was packaged nicely and authentically from NGK. Plugs feel sturdy, and fit in socket and were installed and torqued easily. Plugs will need to be gapped manually with a gauge.
Review: Best quality, most power and efficiency! - I replaced the original Motorcraft plugs with these high quality Iridium NGK plugs in my 2017 F150 5.0 with 76,000 miles on it. I IMMEDIATELY noticed an improvement in smoothness power the first time I hit the throttle! I checked the gap, but didn't need to adjust it thanks to great accuracy out of the box. Probably the easiest plugs to install because DOHC Ford lol! These should outlast any other options due to the Iridium's great durability!
