Just bought a set of ngk6IEX's after a thread nicely started had them on there from spark plugs.com or some website. I was trying to find copper plugs for the sr20 but kept just getting iridium results. Anyway thinking I should have got 7 or 8. Car will be running 300hp when mapped. Should I...
wanna change my plugs
don't want your standard platinum or iridium ones (there not stadard but you know what i mean)
ngk platinum is ~100 PFR6B-9
ngk iridium about 100 as well BKR6EIX
i'm after the part number for the copper plugs for the s15...does anyone know it?
i plan to change plugs...
