88 S4 Injector seats
These are the injector seats from the intake manifold of my S4. They appear to be helping with fuel atomization...although it appears more like its preventing gas from puddling against the intake walls. They were hard to remove, I broke one and and luckily found one on a junk yard. They seem to be extremely brittle as is, if you look at the picture you can see the very bottom one started to chip. Did anyone have a better solution for this, so far I was able to replace o rings on it hoping it will fit. I'm scared with the one slowly chipping off that it don't come off some more and get sucked in.

razor blade and a steady hand. slowly saw at the o-ring in 2-3 spots, then get use a small wire cutter and break the o-ring where you saw'd at. go slow

I've already removed them and replaced them with o-rings. As to replacing them , I wouldn't know where to turn to on that. I was thinking this is a common issue and ppl found ways to get rid of them by using something else to atomize fuel.

i throw them in the bin and replace the stacked height with more of those flat sided base rubbers
two extra where the dual piece atomiser comes from ( primary )
and one extra for the secondarys
no more swallowing broken up spray diffusers that amount to 4/5ths of FA in a worked engine

yes the engine will run happily without the difusers or the air purge to the sockets
( indeed s4 doesn't have purge to secondaries and s5 does )
it may need more fuel in some colder engine conditions
- where i am from we even block the coolant crossover into the inlet manifold
cause that amounts to the other 1/5 of FA when your ambients are 20 to 40 C and your inlet manifolds get hot enough to almost cook from with-in minutes from startup
puddles and wet walls are not issues when your inlets are this warm
