Spark plugs part numbers?

[finnpoulsen]

I'm about to replace my spark plugs and I went to http://www.toyodiy.com to get the parts number. I can see I got two types to choose from, what is the difference and which is the best?

How many km, on the plugs? in the US we have Iridium plugs in the 1NZ 1.5L engine and they (purportedly) last over 100k kilometers. I would say a denso or NGK iridium would work well for a COP ignition. Is yours cop?

the 90080-91229 (L)
is the same as 90919-01176 (J)
as you can see they are the same (K16R-U)
all depends if your car is manufactured as (L) or (J)
(L)ocal or (J)apan SPEC
It wont matter which you put in except the saving of the 72cents
the're both DENSO brand
If your VIN starts with (J) japan
If it starts with a # its (L) local

:iono: go figure :iono:

hope this helps
