I was told I should run these:

50-UR4-IX NGK UR4-IX Irrdium Spark Plugs, Stock heat range, gapped at .035 $6.00 Buy Wish

They are the iridium ones so they are good for 100K under normal driving conditions. I have a few weeks before it starts to warm up for me to do this so I'll keep researching.

You guys have any expierience with the fire sleeves? Since I am sticking with the manifolds I heard these are a good idea as well.

Thanks
