I would use Delcos. In fact I did use the rapidfires and the worked worse than the crap. My choices were stick to the expensive Delcos or go with the *** crap that works better. When Delco produces a plug that works better, you can bet I'll be buying it. Anyway, use what you want. Your car.

 

Correct, It's MY country, and I am gonna support it as best as I can..

 

Sure I believe in supporting my country. If there was a choice, yes. If it was between NGK or Denso vs Delco and all things being equal, I'd go for the Delco (made in Mexico, BTW). When I bought a garden tractor, I looked at Deere first but they didn't have what I needed. I had to be 6 inches wider on the deck than I could have been. As such I had to go with a Kubota or it wouldn't fit into the shed. I can't buy a product that worn't work for me but if there is a choice, I'd go American or bastardized American as some of the parts we buy are.

 

Well.. at least you "try" to support America.. give ya credit for that..
