Denso Spark plugs?

I've been trying and trying to find information. I went ahead and ordered Denso plugs. I like NGK I've just never had any luck with them. Anybody else use them? Any clearance issues?

I use the denso's because they are generally more available and about half the price of NGK's.

Comparing the two brands, it would be hard to note any differences. Denso was the original stock plug for the FB's.

The denso plug on the left is new, the NGK on the right is used

No kiddin! Except for the print on it I don't think I could pick out the differences. And at half the price I might be getting a new set of plugs sooner than I woulda!

Denso is still the original plug installed at the assembly line, although its not 100%. traditionally they were really hard to come by, but if you can find them they are fine
