At least they were only $4 per cyl each so I only blew $24 plus tax.
2/21/07 update. New stock $100+ plugs still did not take miss out of idle.
2-1-8 UPDATE : I replaced 3 of the ignition wires where my records show I picked up some misfires based on my code reader. I am down to a rare occational mis fire. I sat in my brother in laws 2007 Suburban and it idled worse than my 1999 with 130,000 miles. I decided my rough idle is so small I can ignore it.
