New Nitrous direct port injection method

[John R-]

Has anyone seen the new spacers by N.O.S. that go in between the fuel injectors & the head. It raises the injectors & rail about 1 inch higher to allow for a place to inject the nitrous. Similar to a plate system except it has fuel & no2 soft lines plummed into each spacer under the injector. No drilling or bending of hard lines required. Real cool idea, not sure how it pans out performance wise in real use?

sounds like a good idea. but if they were going to do that i could have just taken off my fuel rail for 30 minutes to tap in 4 ports right upstream and under each injector. would have been cheaper too(except when i want to take out the kit). how was their old direct port setup? i've only experienced wet injection systems.
