    Default Denso Spark Plugs

    I need to do a Spark Plug change on my 6.0 soon and was thinking of using Denso Iridium Plugs(Part#5325). I was wondering if anyone has any feedback about these, and if so, could you please let me know what you think. Thanks

    If you search the forums, there is a long thread on spark plugs and which ones are best. Good luck!

    never heard of them, but these truck engines can respond badly to plugs other then the OE Delco plugs. if you search enough on this site you will find TONS of threads on this particular issue.

    Had a buddy reccomend them and I put Denso Iridium's in my dads 96 truck 4.3l v6 and my brothers Jeep 2.5l 4cyl, last summer when I did their tune ups. The truck idels a lot lower than it use to, plus they say the fuel mileage has improved. My brother said his jeep runs better and hasn't had mis firing problems like it use to. I'm putting them in my truck this summer.
