    I agree Matt, i have had both in my hands and they are indeed identical on the outside.

    If there was a difference it may of been right at the very end of the bt run or the very early st engines, but i am yet to see any part numbers to support this.

    I was told it by a guy who has raced an ae101 for years.

    Aware the fitment/ flow rate / part numbers etc are the same, nevertheless, he thought the spray pattern between them was different.
