There is no better O2 sensor than the one AC Delco supplies straight out of the box, resistance is 16.8. I replaced mine in my Buick Lacrosse with the original Delphi that came with the car. a check engine light was installed at the factory, this has been fixed. I have this due to loss of power and rough idle, this should fix it, my old one shows 5.9 which means it's junk, always buy AC delco. And yes it comes with a grab handle, they say he probably didn't look through it and threw it away, it's in a very small clear tube easy to see through so watch out
