    If that is the case, then maybe put it off for the 90k service that I had planned in a few months?

    Stick with a decent quality plug. Cheap plugs work fine too, just won't last as long and may need slight gap adjustment out the box. Stick with NGK plugs for Japanese cars.

    Replaced spark plugs on a vehicle with Hyundai Theta 2.4L I4 engine recently. Came stock with Denso Iridiums. Supposed to last 100k miles. Looked really good at 98K miles / 8 years when I changed them. Just normal used spark plugs. Had no peformance issues. Probably could have left them alone for another 50K miles. I see no improvement with fresh NGK Iridium plugs. Wouldn't be surprised if it would be same deal on Mz5's 2.5L engine. So I think you can leave it in there for a couple more years and then replace with NGK/Bosch/Denso iridium spark plugs. (NGK is what I usually go with.)

    Maybe not another 50K but yes, they seem to be pretty durable. As they age (burn up), you do need to "mind the gap".

    I bought some OEM ones from a nearby dealership for a total of $50 and installed them myself at 80k miles. Easy job. Took under ten minutes.

    It's not bad on I4 engines I've dealt with. On my other vehicle, it took me a bit longer than 10 minutes but was not difficult and the cost of NGK Iridiums was only about $20 for a set of four! They vary in price a bit but getting a set for Mazda's 2.5L should be easy for under $30.
