it wasn't the right part but in the pictures it has the 90 degree elbow but it didnt arrive like that. Then there's a 20% restock fee and pay for shipping to return it so its probably not worth returning.
***UPDATE*** Construction is great and the catalytic material is a nice addition. This is being used on a 2024 BMW X5M LCI with hi-flow catted primaries and the large-opening cap appears to be working. I had a lambda – delayed response code for several drive cycles, but now it’s cleared out with no CEL. My diagnostic tool says the code has been stored, but is currently not present.
They worked as expected use the small hole tip had a cel come on and a few key cycles later it went off by itself great job on recommend parts
They work perfectly
Perfect
