Full Send Diesel has specifically designed our -10AN High flow fittings for people who have issues with oil backing up in the turbo. Many other comparable products are a restriction point for the oil draining from your turbo.

This results in oil pushing past the oil seals inside of your turbocharger. Our high flow drain fittings are punched out as large as possible and feature a smooth contour on the inside to increase oil flow and lesson the restriction that other products carry.
