I'm about to finish my 2.3l build on my Evo 8 and noticed that my ID1000cc injectors seem to be loose. I wanted to see what type of injector grommets (insulators) you guys are using to properly seat the ID1000's. I currently am using a 204 lower cushion ((o-ring) part # 92.1) that Injector Dynamics supplied me with after getting injectors cleaned.
Any advice would be appreciated!

 

I could use some too but the ones on the intake manifold side.

 

Those are the ones I'm taking about, going from the bottom of injector to intake manifold.

 

personally i use stock insulators.

 

Got ya, I will try that if I run into any issues. I'm thinking the lower o-rings (cushions) just need to heat up to seat properly.

 

if you still on stock IM,stock insulators should sit snug,if they dry,cracked or hard and brittle,then you need to replace them brother.
