When driving on track oil pressure is everything. At anything over 1G of Lateral grip, the oil in your pan can slosh to a 45 degree angle. This can cause low oil pressure - not a good thing for the health of your engine. Our DIY weld-in baffle kit is designed to keep a plentiful supply of oil near the pump pickup which will prevent oil starvation. Once the oil pan is removed, installation is a breeze. Weld it yourself or take it to your local welder. Consider it cheap insurance against engine failure. DIY Weld-In Kit Includes 2x trap doors.
