I know there are a bunch of threads out there regarding using the Hyundai or Dorman parts, but most favor the Bosch part.

However, I’m an idiot and am not sure if I’m looking at the correct part as there is one that is a cylinder style with the hoses on each end, and one on top of it with hoses on it too.

Is it this one:



or this one:



I think it’s the second one, but I can’t find it on Rock Auto. Can someone throw me a bone? I hope this helps someone as I feel really dumb.

 

And I should probably give a bit more background. Obviously I’m getting P0441. However, my SAI pump only comes on intermittently from cold starts (not just the engine, but when it’s physically cold outside). Are they related?

 

The lower part.

 

Thanks! I can’t find it to save my life in rock auto. Got the Bosh PN by chance?

 

I just put this one in my P38 back in October and it seems to be working just fine.

 

OK, I just found this one. It’s a Bosch. From what I’ve read, it seems to be better?

 

I would expect both to work just fine. I'm am sure we will compare notes if one or the other goes bad too soon.

 

OEM Hyundai units work excellent, and you can go with a Bosch unit as the prices have come down a lot vs what they used to be. I personally use the Hyundai part = zero issues. You want to avoid the generic valves by like BWD, Dorman and companies like that. Those fail quickly from what I've seen.
