No, not quite...it doesnt matter where the hell a spark plug comes from.
And yes I made the two latter locations up. I am FAR from ignorant.
A spark plug either sparks or it doesnt. It's either the correct heat range or it isnt. I've used just about every brand with exception to the multi electrode gimmick plugs being someone who uses what is available, and I have never had a problem as long as they were properly gapped and the proper type for the vehicle, and I'm talking severe conditions.
Ignorant is judging something based on where it comes from rather than how it works.
Kind of like calling someone ignorant for making a true statement when it doesnt fall in line with your opinion.
With everything being made in china including the computer you're using to call me ignorant, it's pretty hypocritical to make a statement like that.
There's literally a TON of stuff made here that sucks. It's hit and miss no matter where it comes from.
P.S. Chances are the reason a product from china MIGHT have a problem is because of the shortsightedness of an american company quick to push off the labor there with very little QC or oversight...
