    I run single electrode spark plugs in my 3.4l engine? About a month ago I decided to swap out my plugs and wires. So I went to napa and asked for Denso plugs and wires. Guy comes back with the plugs and wires and I open up the plug boxes to check to make sure the gap was correct. Yes, I brought my own handy dandy Feeler gauge :p All the gaps were fine, so i went home to get to work. Logged on to TW to make sure there wasn't anything unusual about the plug changing on the engine and noticed everyone says to run the dual electrode plugs. I say to myself, "hmmm... The plugs I just bought are only single electrode... Whatever I'm sure they'll work fine." and proceeded to swap all the plugs and wires. When I finished I fired up the truck and she ran perfectly. Better than she was with the old plugs in fact. Should I go back and buy the correct plugs or will I be ok with the ones I have? Is there any danger in running the plugs I have? Thanks for the advice.

    i think you will be ok. a cylinder only needs 1 spark to ignite. you can't ignite it twice.

    Thanks for the responses. I'll probably grab a set of the correct ones today. Today's the first day I'll be near any sort of parts store since I switched them out. Around 100 miles round trip to the nearest Napa store. Now another question... Does anyone know the real reason why you're only supposed to use the duals? So far every thread ive found says, "because Toyota says so."

    I never investigated as to why, but I have tried different single electrode plugs on teh 3.4, and in a few cases, the CEL came on. To add, the truck ran much better (smoother, stronger) with teh dual electrode plugs.

    I'll see how she runs once I get the correct plugs in there. There was a noticeable improvement in performance with these plugs that are in there now so maybe the old ones were just so bad that even the wrong new plugs made it run better... Who knowss
