I was perusing the NGK USA website looking at spark plugs....as one does when looking for esoteric subject matter to stimulate the mind.

Anyway, the FAQ (courtesy of WristPin) lists the NGK V-Power plug BPR5EY (Part #1223) as being correct for an 85 22RE 4Runner. If you go to the following link however, you will see that you have two choices in "engines" (three counting the turbo).

NGK Spark Plugs USA

One engine is "2.4 L4 22R-EC FI" which lists the plug above. The other engine is "SR5 2.4 L4 22 REC FI" which lists a different plug: BPR5EY-11 in the V-Power with a larger gap, 0.044 vs. 0.032.

Now unless someone knows something that I don't, there was absolutely no difference between the engine in a Deluxe 4Runner and an SR5 (I own an 85 and used to have an 86 and ran and maintened them together).

Anyone know why they list the two different plugs?

Second question. Has anyone tried the Iridium plugs? Again, they list two different ones for those two engines with two different gaps. I've searched and read some threads where platinum plugs are not good for the 22RE but the description of these plugs leads me to believe that they would behave like normal plugs (but with Iridium coated electrodes).

Any experience out there? I found nothing quite this specific when I searched.
