NGK's
They were AC Delco. Today I drive the truck and it has a miss under load. So, I go to advance and argue with the parts guy untill he gives me new plugs for exchange for the platinums that messed up. He said they don't have a warranty of any kind. Then I point out to him the warranty is good for 3 years or 100,000 miles. I've only put 10,000 miles on them and its been 13 months. Well, today I put the new plugs in. And I realize 2 of my MSD wires are messed up. So I'm thinking the MSD wires are the reason for the miss. I went to O'reillys and bought the cheapest set of plug wires. But it got dark before I had a chance to put them in. I tried, but the manifolds were still hot and I don't enjoy getting my hands on them. Tommorrow after the cable guy comes to disconnect my cable and internet, I'm changing the plug wires. Hopefully that fixes the miss.
