What Spark Plug To Use For 1998 Sc300 Thanks

[Scott Gordon]

Hi ,

I would like to replace my spark plugs on my 1998 sc300 and would like to know what the OEM plug was it seems folks refer to the oem plug but don't name it?

Also from what I have read should I replace the plugs in the car with with an Iridium plug or should I use platnum ?

finaly from what I've read I should use either Denso or NKG is one better then the other it seems NKG are a bit cheaper?

thanks

Scott

stock plugs are denso platinums.

I've used both, but the Denso's produced a higher spark compared the NKS. Also, 88-today toyota engines use Denso's so I'd stick with that.
