While cleaning up my inlet manifold (bottom half) i managed to break one of the plastic things inside that the secondary injector sprays into... like a mesh on stilts..

Is it required? if so how can i replace?

 

You can order it from any Mazda dealership. If it's cheap (which I suspect) then replace it. Mazda put it there for a reason.

 

Its to help atomis the fuel so it can mix better with the fuel but its not realy need if you have good clean inj

 

Yeah i realise its there to better the atomisation of fuel.. the plasti on both are brittle and old so thinking just replace both while im at it.. ill be upgrading 2ndary injectors to 1680cc after motor is run in so the more atomisation the better i guess

 

diffuser will run without but there for a reason, my mazda dealer got it for me but they didnt stock it so took a week

 

well you may be in for a little supprise, i think the last time i bought some of thoes they were like 40 bucks a piece

 

chek mazdatrix..they got em....

 

53.72 for a pair.. not too bad i guess
