I've never had issues with any wires... The last set I bought was a cheap aftermarket set and I noticed zero difference from the Accel's I had on before. And when I say cheap, I mean $12 for the set....
I had gotten a set of the yellow Accels mainly because they had a boot more heat resistant (for headers) than stock wires. Also yellow would stand out against everything else, emissions equipment/hoses, as well as the engine itself, which is black.
These are for a small block Oldsmobile. I've seen a few pictures of people who used Accels, and they looked pretty sloppy. Was thinking the Moroso ones would be a little neater in fit. I looked at Taylor wires as well, but don't recall seeing any for Oldsmobiles, just Chevy and make-your-own.
Also I'm seeing sets listed for Oldsmobile and Buick V8's. Doesn't quite make sense to me, would think beyond HEI cap boots, lengths would be totally different (front distributor vs rear, etc).
