Hi:

I have heard many complaints on these spark plugs, though they have been nothing but great news for me so far? In fact the car ran better! Why is that? What do you think causes problems for so many Maximas with this plug?

I've had them maybe...4k miles now. Are most of the problems right after install or are these going to **** out on me soon? Thanks for any info.

 

There's nothing wrong with the plugs. I have had them for well over 30k+ miles. And also the only reason your car ran better is b/c they are new plugs not b/c they are Bosch +4. When you change to new plugs you will almost always feel some difference.

Shing, thanks but I knew that much. I'm just saying that many people put these in and the car runs worse? I was just noting thats not the case for me. I know most of the gain was because my plugs were old as fart, likely original.

maybe these people are not puting the coil pack back on right or something? Someone emailed me once, and I told him to check the gaps incase he didn't get the right ones, and to make sure all the plugs were getting contact with the coil, however he is not the first one to complain.

Another person (seeing my sig) told me if my car starts to run like crap, then throw away my bosch 4s? So whats the bad rap? At least I know you don't have any problems.

 

They seemed like a pretty decent plug.
