I have used a couple dozen Sierra coils and not had a problem. I don’t know where they are made. You sometimes have to hold pressure on them inward toward the center of the mag plate while tightening them down so they don’t rub on the flywheel.

We westerners have been at the top of the industrial and economic food chain for so long, that we think we are invincible. So when we buy things, our primary driving force is cost. The last thing most of us think of is national pride or national security. The Chinese eat this up. They can steal, and I mean STEAL, designs with no threat of ANY consequence, make products that are either average or inferior quality, sell them for a cost that they know we can’t resist (because we allow these bogus products into the country) and put their opposition out of business, one company at a time. Nobody cares to realize that they are taking over the world with patience and determination, slowly but surely, without ever having to fire a single shot. I am not a conspiracy theorist. This is just a fact.

Crosbyman, you keep bringing up your American made lawn tractor. Hey, we are far from perfect, I am sure. However, I can’t help but wonder where that transmission itself was built…..or where the seals themselves were manufactured….That’s the other thing about this problem. It is very intertwined and complicated, and has slowly grown that way over time, because we have let it happen.
