Time to swap the plugs on my old girl, last time i did it I used the pricey NGK's they recommend at Super cheap for like $25 a plug.

I remember reading however that the cheaper copper plugs are as good or better just that you should change them more often.

Whats the consensus on this? What would be best suited for a mildly modded gt like mine that runs a 15 psi tune daily and 18 psi when i want to go just a little bit faster.

How about heat range and gap etc etc.

Experts please do your best to bore me with spark plug chatter.

As above. I just use the recommended iridiums, but gap them down to about 0.6mm

Sounds like the jury has returned a verdict, iridiums it is.

What do your current plugs look like? Black, sooty, wet, or white and dry. You can choose heat range to adjust for how it is tuned and/or running. In NGK 1 is hotter and 10 is cooler (check their website, as I maybe ass about face). You can also choose gap size (some NGK’s may have a -11 etc meaning 1.1mm or -9, 0.9mm). Bigger gap I believe gives a bigger spark, so long as you have a coil to match and leads with appropriate resistance.

Electrode size and shape, and protrusion most likely aid ignitability, whereas material e.g iridium enhances longevity.

Cheers,
Dogs
