Thanks for all the information!
The OEM spark plugs on my car call out to be changed at 100,000 miles. Would purchasing and installing the Iridium NGK 92145 spark plugs also give me the same maintenance interval as the OEM spark plug? (Being that they are iridium spark plugs)
Yes, they should give you the same service life as the OEM plugs. However, whatever the manufacturer lists as the plugs' service life is what you should expect.
It is very likely that any iridium/platinum topped plug will list its service life to be 100K miles, which is the same as the plugs that came in yours. But even if the plugs you buy do not promise 100K, they will still work just fine your engine*.
Also, be sure to check the gap on the new plugs. They will likely be the correct gap already (0.044"), but I have seen instances where the new plugs had to be re-gapped to match the spec'd gap, so it's not unheard of. And if you do have to alter the gap of the iridium/platinum tipped plugs, you must use the correct type of gapper, which is NOT the old-school slide-a-gap kind that use the plug's tip as the fulcrum to bend the electrode.
If you do not have a torque wrench, get one (1/4" drive will work, but 3/8" drive is better). The plugs will need to be properly torqued down into the cylinder head. You'll have to look up the torque spec for your particular engine, but it will be pretty low, like 15-20 ft/lbs.
* - As long as you don't crazy and buy one of the gimmicky kind like E3 or RapidFire. Those aren't known for their robustness in operating in any engine, any platform. Stick with the known name brands, single electrode, and you'll be fine.
