I always get mine at NAPA also. They always have a hard time looking up the actual UR5# as they use the NGK stock #2771. Have them look it up with the #2771.

I just checked on the #2771 plugs for you. If you need them I can have them into me in a day or 2 on average. If you want a $ shoot me a PM..

I believe the NGK R5674-7 is designed for high combustion chamber pressures. It's electrode is not sticking too far out, like a stock design plug(or like a UR5) and therefore is not as prone to the spark being blown out.
