Superior K0136
No I'm not a dealer...not promoting parts.
Released in August 2017...who here has used them...what have your results been?
More importantly...who here has cut one apart to see the guts. Measured any of it, etc.

I've had great success with new AC Delco production check ball capsules...just be sure to seat them and double check for leaks in that area. But I'm always open to trying new things.

 

Is that a variation of this guy? Although I see with the Superior one you remove the checkball capsule.

No, I don't believe it is the same at all.
Sonnax makes a lot of wonderful parts...I don't feel like this is one of them. I will personally never use one of the sonnax capsules

I agree, I have never had a problem with the oem servo capsule. If there is no problem here, go to where there is an actual problem, and address that. So called fixes to where none is needed, just pay attention to what is going on.

 

yes very interesting....is the ac delco check capsule P/N the same as the old one ? ( or did the P/N ever change ? )
