anybody can tell me the bosh 1600CC injector o-ring size or part number or where I can purchase a few? Also trying to pull the diffuser out of the secondary injector holes, how much force do I need with a pair of plier? I dont want to break them and have them fall into the injector hole, advise? THanks

 

The diffusers should come out very easily. There is a rubber gromet that you have to pull out first to get access to the diffuser. Like you said just becareful so you don't break it. Good luck. As for the O rings I just took my injector to NAPA and compared it to the ones they had there. I had to buy a chevy V8 kit so it came with a lot of O rings. It was very cheap.

The diffusers are tricky to get out. You can screw a 10x1.25 (?) bolt in there and pull them out with a little fuss.

You can get the injector orings from kgparts.com
