This part may save your engine!!
The MMR cylinder head oiling modification (oil balance lines ) joins the left and right cylinder head together with the MMR Balance tube and fittings. In the event that the VERY small factory pressure orifice is clogged the head will continue to receive oil due to the MMR balance tube. MMR has seen hundreds of cylinder heads ruined because of oil starvation, this simple, easy to install mod will guarantee that your cylinder heads always remain lubricated along with perfectly balanced pressure.
THIS IS A MUST FOR ALL PERFORMANCE APPLICATIONS!!
