In the middle of a HG job on my 2000 D2. The Rave manual says to discard the SAI adapters and fit new ones. But they're like $55 each! Is it necessary to put new ones on?

 

I've never replaced the adaptors. replaced a couple of broken sai pipes
as needed

 

you only have to replace them if you damage them coming out

 

I re-use them also.

 

reused mine. Just don't put them in too tight. Use anti-seize on them - that gold paste.

Usually the problem is that these move when you are taking off the large bolt on the SAI pipes. You need a crow's foot to keep them in place.

Maybe putting them back in tight is good. Just don't break them.
