NGK ILTR5A-13G
Denso ITV16TT
Who knows? Above sold by mx5Heaven and AutoLink, vehicle specific for mk3 2.0 models.
Mx5Parts offer 3 versions but no part numbers quoted.
Some sellers quoting Denso ITV 20TT for 2.0 model?
Blooming minefield! You do right to query it. Sorry can’t be of more help to you.
