Are T5 and 2.4i sparkplugs compatible?

Are T5 and 2.4i sparkplugs compatible?
Bought this one for my 2.4i 07 -
NGK
What concerns me is that Amazon says it's not compatible with my s40 2.4i 2007, even though I've heard it is.(from here)
And it says it's compatible with T5.
Checked the gap, it's good. Checked the thread, it's good.
Then is it compatible?
Thus, can I ignore Amazon My car recommendation?

I used RockAuto and compared the two plugs recommended for the different engines and they are exactly the same size and heat range with a slight difference in spark plug gap. Although Iridium plugs are overkill for a normally aspirated car it won't hurt anything.

You shouldn't notice anything. Iridium plugs with a smaller gap are used on turbo engines to prevent detonation and spark blowout. Neither issue is of concern for a non-turbo engine. Since the Iridium plug is more expensive it's even more reason not to use them. So did you find a screaming good deal you couldn't pass up?
