    I have a supercharger. Dealership said they couldn't get the Denso IK22s but had NGK Iridium's (#2309?). I went ahead with this. I'm not familiar with the latter...

    Thoughts?

    Denso IKH22 (5345) is the recommended plug for supercharged Tacomas, like ours. NGK Iridium 2309 is an equivalent plug. Both are iridium, which should provide longer life than other materials. Both also run at a similar (cooler) heat range than "standard" plugs, required when running forced induction.
