I am totally into Denso TT Iridium - I put those (the correct model obviously) into pretty much all of my cars, except for the V12s - there was some kind of reason as to why that was not possible.
Anyway: TT means: Twin Tip - there is a tip on each side.
My 3L V6 S-Type wants IT20TT
Your STR wants Denso IK16TT

If I found the correct information on the net, the first TT spark plugs were introduced in 2009.
That would be 1 year AFTER they stopped producing the S-Type.
Obviously they could not specify TT spark plugs as OE spark plugs for that reason...
I - for one - to not refuse to accept improvements in technology...
