LF3/LF4 Camshaft With Upgraded Fuel Pump Lobe
This product is currently sold out.
This starts off as a stock OEM ATS-V camshaft. We then upgrade the fuel pump lobe on it. This increases the flow potential of the factory mechanical pump. Some people have had engine failures from simple bolt on cars without this mod. This is an absolute MUST HAVE for anyone wanting to flirt with E85 fuel. This works very well with our ATS-V tune and Flex Fuel Conversion Kit. The LF3/LF4 is extremely hard to keep timing correct, so we highly recommend our Cam Sprocket tool which can be found here.
