Why brass only? Unless racing or by alot of moisture no gain at all. Biggest issue is the thickness of the cap to keep the terminals aligned.

I've had one aluminum contact cap, ended up replacing it not too long after installation, tracing was one of the issues, maybe it had thinner plastic in the body. I have learned that the TBI does not care for any multiple electrode plug, platinum etc., have had best luck with ACDelco CR43TS
