going to change plugs on my 2000 4runner sr5.gap is .43 since i've never dealt with a dual plug do you split the .43 between the two points or is it .43
each side.

Gap is measured from the electode to ground arm regaurdless of number ie 1 ground would be .43 center to arm 2 .43 from center to each arm and 4 .43 from center to each arm etc.

Have fun and remember DO NOT OVER TIGHTEN THE PLUGS. Your head is aluminum it will strip out. Also use dielectric grease on the caps so you can pull them off when you need to later.

use one of your old plug wires to thread the new plugs in not a socket, then finish with the socket, this will prevent cross threading.

You need one of these to set the gap on dual element plugs. Don't use a normal flat blade type--only the wire type in the pic. If .045 won't pass and .040 will, you are good to go. Like thor99, I use an 18" inch length of 5/8" inch fuel hose to thread the plugs. Makes it almost impossible to cross-thread.

What's the difference?

What's the difference?

Because the ground electrode has a concave shape on the end to maintain an equal distance from the side of the round center pin, the flat blade can't measure the distance accurately. The wire can slide through the curved gap.

Awesome, thanks for the tip.

does it matter if you use the single type or the double

Use correct plugs every time. The correct are neither double or single they have four.

Shit got my BMW mixed up there doubles are correct NGK BKR5EKPB11 Double Platinum are what I used. Do not use singles

 

[BlazeRunner]

The correct plugs are dual electrode, just like TheDurk pictured. Denso or NGK
