Mercury Marauder Injectors

[SilverXJ]

2 beam at 20°.
Spray orientation angle 90°

Can you expand on what those two mean? Also, how do they compare to the Jeep injectors, besides the flow rating?

Two beam and spray angle are all needed for better atomization in the specific intake manifolds.
Spray distribution is also determined by the number of intake valves and location in relation to the injector, a better engine/throttle response is gained when the spray is directed onto the intake valve.
This is why some injectors can be installed in one position/ rotation only, using a locating lug on the injector body.

Jeep injectors are one beam with about 20° spray angle. since non of the common Jeep owners or even well known injectors shops have the tooling or knowledge for matching a "better spray orientation" one should keep the upgraded injector characteristics as close as possible to the stock one.
