Perfect
End broke off the original when removing the intake. This replacement was perfect - brand new and identical. Oreillys said it was a dealer part and they couldn't get it. Thought I'd really screwed myself. But luckily found it here. Was delivered fast and at a reasonable price. Took just a few minutes to install. 2010 Buick Lacrosse 3.0 V6. Thank You for offering this product.

Seems to correct a problem design of GM in the original component
Original design by GM over time was found to be less then desired. New design appears to correct the problem however new part is dealer only and seems to be premium priced.
