fuel injectors on a 86 S4 N/A . .400cc?

Looking at replacing the leading fuel injectors on my FC 1986.

I seem to recall 400cc's were what came on the car? .. . . . . .What fuel injectors should I put in there to get it back to OEM stock so I can smog it?

welcome to the board.

i think they are something like 440s, but to get to your question, why not have your injectors refurbished - especially if you're keeping it stock? that way you don't have to mess around with trying to "find" some.

Second this, the OEM injectors are great.

I had my blocked, filthy injectors refurbished and flowed (within like 2%) by Maple Racing in North Houston. Cost was like $25/injector, but he does just a basic cleaning and flow for cheaper also. Car is now superlively compared to before and revs out fine whereas before I think the secondaries were dead, and the car would hit a wall at 3800 rpm or so.
