NGK Spark Plug differences (1 Viewer)

[WarDamnEagle]

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.

Not sure this helps or not. Toyota only lists one plug for the 22r/re engines 1981-1995, W16EXR-U. They also list an optional "platinum/iridium" plug, P16R with the gap reset to factory specs.

=======================

Along the same lines of confusion ... The 3FE was used from 1988-1992 in the FJ62 and FJ80 Land Cruisers. The engine is mostly the same (different coil/ignitor), and Toyota specs two different plugs. The 3FE in the FJ62 uses the 22RE plug above, W16EXR-U. The 3FE in the FJ80 uses W16EXR-U11. Go figure what the "11" means. Plus, both 3FEs use the same optional "platinum/iridium" plug, P16R, but the plugs for the FJ62 need to be regaped to factory specs (.032"), while the plugs in the FJ80 do not get the gap reset out of the box (.044"?). My guess is the '11' indicates same plug, but larger gap out of the box.

NGK, of course, lists (mostly) different plugs for the two engines.

Maybe the SR5 gap at .044 makes more power? And if you got an SR5 you want the best right?

 

[WristPin]

i dont know why the gap would be different.
maybe the engineer for toyota had 2 shot extra espresso that morning.

wait they drink tea. maybe he had two teaspoons more honey that morning.

the iridium plugs, like platinum, are designed to ground backwards. as well as forwards. but always both ways on the one engine.

they will serve no benefit on a 22RE only they will last much longer than a v power.

the dual ground plugs are made for COP (coil on plug ) DIS direct Ignition System, and ignitions with high energy igntions, ( but not chevys HEI)

you shouldnt use any thing but a vpower or a regular denso. but the regular denso is just like the regular ngk.

of course!
oh, and while your at it, put some racing stripes on it, for that extra power punch!

the '11' is the gap

which is .044"

i'll add this image to that ngk thread i did in the FAQ

Thanks WristPin. And now I know more about spark plugs than I ever thought possible! Guess it's my own fault as I started the thread!

That chart is a nice addition to the spark plug FAQ

I haven't tried Iridium plugs yet. I just use the traditional spark plugs. So there are different kinds of spark plugs. I just came across a pulse plug. What is its difference from an IRidium plugs, NGK, and a traditional spark plugs??

you forgot one. Turning your hat around backwards.....

wristy, would it not be considered a benefit that the plug last longer?
