cheap parts
I received the parts quickly. The gasket and harness worked awesome, and so did the knock sensors...at first. They lasted about a week and the check engine light came back on. This was a bargain for the intake gaskets and knock sensor harness. But I ended up having to buy ACDelco knock sensors. This job isnt the easiest to do so I dont want to do it over.
