Query: Cap sent not what is pictured.

The picture shows a cap with copper contacts. The first one I ordered, I got an aluminum cap of different brand. I needed a cap so I used it. I ordered another thinking maybe they sent the wrong one the first time. But again I got the same cap, NOT Tru-Tech with copper. From now on I get my caps retail, so I can see what I pay for BEFORE I buy!These caps last about 5,000 miles before engine idles rough.
