SPARK PLUG – 16EA – CHAMPION COPPER PLUS 570, recommended and proven to run best, no CEL problems, cheaper price, and will exceed the recommended 30K mile replacement schedule.

NGK 5306 gapped to .045"

I didn't choose them, they were sent to me from Inertia with the rest of my performance build parts. When I pulled my stock Champions I thought they looked pretty good considering how long they had been in the engine. I'm interested to see how well these NGKs hold up.

x2 I have tried other from platinum iridium to E3 none have improved fuel economy E3 actually made it run like crap the others seemed to run ok you may get a longer change interval but the extra $$ I would want a performance or mileage improvement. This is old school before we wasted money throwing away good plugs but the copper ones can be cleaned electrode filed flat and re-gapped for another 30,000 miles at least. When I went to school for auto mechanics we never threw away working plugs cause they were old and we rebuilt parts like starters alternators power steering pumps and boxes not like todays mechanics in our throw away society lol
