Do I need to use the metal gasket that comes with the sparkplugs I bought?

Also the manual mentions a 16mm plug wrench/socket, do I really need to get this or will any plug socket generally work?

Thanks!

Metal Gasket ??

Uhh never heard of nor seen a metal spark plug gasket..

Any pics ?


And I think when I just did my plugs I used a 5/8" from vatozone

Elton

The metal gasket should come with the plugs.

Bird333

Yeah, I mean the washer. So I do need to use it then?

Yep-you do--and anti seize as mentioned above

stir_fry_boy

Do not gap, take the plug out of the box, remove the cardboard over the electrode, put on anti seize and put in the engine just the way it is.

He needs to set the gap!

my plugs are 13/16ths..lol..and ONLY 13/16ths plug wrench will work...o well

you can check the gap of the plugs..i can almost gurantee you that they are already the correct gap....i always check mine just in case..and i've never found one that was wrong..lol

Are you talking about oem plugs??

Don't know about the 4 cyl engine but at least in the 5vz-fe engine, you only use dual grounded electrode spark plugs. I don't know if the 4 cyl has them or not. But now-a-days you rarely need to gap plugs. I can't remember the last time I gapped plugs.

Im Running the NGk-R BKR5EKB Dual electrode spark plugs. Gap calls for .044

You don't gap those. If you do, you ruin them. The distance between each of the grounds has to be precisely the same. If not, only one ground instead of two will work and you might as well put $2 platnium single gounded plugs in it.

i've tried about 10 different styles and brands of spark plugs...none seemed to be any better than the cheapo depo ones from oreiley's..so i use them..why spend a crap load on 4 name brand or whatever plugs...when u can spend just a few bucks on some cheap plugs that do the EXACT same thing...........

Use OEM plugs as they come out of the little box with some anti seize.

16mm is 0.629 and 5/8 is 0.625

Pains me to say this...you are correct! Just got off the phone with NGK and he confirmed it. Looks like im putting in some new plugs today! lol

Just an FYI--the only reason Yota used the twin ground electrode was because of the wasted spark ignition system--it fires the plugs twice as much--i.e...two electrodes.

I am running iridiums--i guess just because......

Whitey13

Single electrode? I just pulled mine and they were denso iridiums(single)

Well, at least Toyota hooked me up for free!
