Disregard earlier reply. Morning brain read this as oil cap.

You need an S-Type cap and I'm only seeing the N-Type so far... Looks like it may be discontinued. The only S-Types I see are from way back or clearly replicas from questionable sources.

 

So S-type is what radiator cap we have?
I guess i'll have to go greddy or apex or something.

 

Yep, fortunately you have plenty of options. It's kind of odd TRD only offer the N-type now given how many of their vehicles ran the S-type. Perhaps the sales just weren't there.

Another option would be to buy whatever S-type cap for the cheapest price (That still appears to be good quality) and buy a TRD sticker for it. Looks like there are a couple different sites offering them.

It's literally all TRD did anyway.
