hmm Im not too sure about the consistency of Mr Kinuagawa.
My right angle oil line feed is different to both of yours.
Initially I received the wrong V band flange but I contacted him and I had a new one sent to my door inside a week.
He also had 2 different listings for the T67 on ebay with one being $50 cheaper, I messaged him about this and he said they were exactly the same...
nothing major but something to be aware of if you buy one.
Good luck with the tune OMY31T im interested to see your results with the stock plenum vs Simon's with the "freddy".
