was looking to fit this rail ^ when i replace the plenum with the new powder coated one, but it say about grinding off some metal Note: If installed with an old-style upper plenum, you will need to grind away a small amount of casting above the #1 injector for the connector to clear. now i need to do this before i powder coat the plenum.

 

so were about and what do i need to grind off any help here would be good as i need to grind it in the morning

Dan, have you tried CZP live online via their 'Chat' ?

 

They might be able to advise

think it mite be this

if you get a 95 plenum the grinding isnt needed.Youll need a die grinder otherwise with a carbide bit.Thats what i use anyway.

i have a spare plenum here so a using that,yes was just reading on the later on you dont need to grind it. i think know now were i need to grind
