Hey guys. Looking to do my spark plugs. Everything points me to iridiums, but am wondering if anyone runs anything else that works just as fine??

You can use other kinds, they just may need changing more often. I have a set of "single" iridiums in as the name brand 4 were on clearance for like $12 due to some Supercheap auto clearance sale, they hade none of the double iridiums left so I just found the compatible type and re-gapped them. No issues a year later.
As long as temp range is correct, and the gap is correct, it will be fine. The non iridiums will just deteriorate more quickly, so it may be worth checking every year and adjust the gap again/cleaning.
