Fitting ID injectors with OEM type lower cushions
 

I am about to replace my current Bosch EV1 injectors with some new Deka injectors that are basically the same as the ID ones to look at. The Bosch ones require me to pull out the OEM diffuser and seals from down the hole and then fit an adapter to downsize the hole for the 14mm o-rings.
I have since read that ID and other places sell kits where the injectors have a Denso (OEM style) cushion on the bottom of the injector replacing the O-ring so they can just straight drop into the engine without the need for additional spacers/adapters? Can anyone confirm if this still works when the OEM diffusers have been removed please as I don't recall there being a noticable step do the hole when the diffusers are removed. Just a plain hole the would allow the injectors to just fall right in?!
I could always put the diffusers back in but I gather it is advised you run without.
So which is my best option?

Thank you

I ran my IDs with denso cushions for a while and didn't like it, they seemed like they didn't seal very well. the denso cushions are designed to run with the diffusers in place.

you can either run FFE lower adapters and use double 11mm o-rings

or you can use adapters from xtreme rotaries in australia to run 14mm orings if you want.

(I actually have a set of these I'm not planning on using. PM me if interested)

Thanks for feedback. Good to know your findings with the cushions. As it happens I have the Xtreme rotary adapters on my Bosch injectors that are in there so maybe I will just stick with these and mod to suit if needed. They are a pig to fit in the block I found as there is no lead in on the hole. So I look forward to taking them out and refitting them again!
