2007 Tacoma 2.7L Regular - 145K miles
I bought 4 spark plugs iridium Long Life from Denso.com specific for the Tacoma.
3 of them have over 5.2 KOhms 1 has 4.5 KOhms of resistance.
Is it something of a concern? Is it ok just install them?
That much difference I'd go back and get a new set that we're all the same
