Need to cap secondary injector bungs - what to use?

If you want a permanent fix....
Remove the LIM
Tap the holes with your favorite size pipe thread
Screw in the plug with a small amount of thread sealer

The pipe thread will prevent it from ever goin too far in and falling into your engine. The allen head makes it low-profile for a clean look and also saves space for working on your engine (no busted knuckles on this one!). You can use a straight thread with a bolt if you want...

Another option is freeze plugs and industrial strengthy jb weld or devcon. The same stuff is used to seal the intake ports on a peripheral port motor. Ground Zero provides freeze plugs with their lower intake manifold to seal the additional injector bungs if not being used.
