LS3 Intake Vacuum/Boost Reference Port Adapter to 1/8" NPT (LS3 Map Sensor) Push to Connect Fitting Not Included
Adapting a 5 Bar map sensor or to 1/8" NPT for auxillary connections is often an issue if you are not using a factory LS3 intake. It is difficult to plug and then limits your Vacuum reference ports as well. We have created this plug/adaptor which comes with an 1/8" NPT port for screwing in 3.5 or 5 Bar map sensors, push to connect fittings or plugs.
These ports have an 1/8" NPT female ports for hooking up push to connect, AN to NPT ports and more! You can also screw an NPT style MAP sensor directly into.
Note: We suggest reusing factory self tapping style hardware to retain this plug as the intake does not come with threads, however this plug is used in other intakes so comes with other size hardware.
This listing is for quantity one.
