Nissan did not learn from the MR16DDT. The KR oil feed line is designed exactly like the MR oil feed lines. And if you are not aware, those lines clog and fail ALL THE TIME.
This kit replaces the stock feed line with a performance based feed line that is designed to see much more extreme heat and vibration than your daily commute will ever put into it.
A custom made socket is available to make the install even easier.
Install is a breeze, and only takes 30-45 minutes with the appropriate tools.
