Review on NGK 6046 DCPR7EIX Iridium Spark by Roderick Reynolds

Revainrating 5 out of 5

Great product - needs clearance for HD

Just installed on a 2007 Street Glide. They came out of the box with a 0.025 gap. Harley recommends .038 to .042. I set them to 0.038 to account for wear and put some dialect grease on the connectors. Lubricants are not recommended for these plugs as the coating acts as a lubricant. In this case, reduce the torque by 30% to avoid over-tightening. Watch my full installation video on the unboxed YouTube channel /channel/UCQo58nrEgVVPDEgy5wwJ7dw
