Description
We recommend this pump as an upgrade for the OEM LS3 oil pump in applications with added oiling system demands such as large external oil coolers, larger bearing clearances, turbochargers, etc. This is also the recommended oil pump for extreme (8000+) rpm applications. We recommend this pump as a replacement for the OEM L99 oil pump in all VVT applications.
