If you're replacing your turbo with any Garrett based turbo kit or if you already have a Garrett on your Mazdaspeed 3 or 6 and want to get a better oil feed line setup, the Kozmic oil feed line is a great solution. It's a stainless steel, braided line that won't expand or bend very easily and will deliver a constant flow of oil to the turbo. Stainless steel fittings are included in the kit to make it a completely bolt on setup. The fitting on the turbo side is also a restrictor which is necessary for the Garrett ball bearing turbos. If you're wondering, these are much more convenient to put on when you are putting the turbo on simultaneously.
