I just asked the difference. And if you looks at my profile you can see I support innovators. i.e. MS manis and Top -feed fuel rail. I wait 5 months for the Manis from SZ and about 6 months for the Fuel rail from DA. I dont mind waiting. I spoke with ash about 1 hours ago and asked him if the were copys, he basically told me yes but not very good copys.
