The consesnus is that Bosch, no good, Bougicord, yes.
Though... I once had bosch wires for many years and they were perfect.

Also note the metal sleeves, not sure where you get them from, but the most recent bougicords I bought from fcpgroton have no metal sleeves, and came in a plastic bag with no "bougicord" written on the wires. Word has it Bosch still uses the metal sleeves, but i don;t know for sure. For these older cars, it is diferent to really be sure where these parts are made these days. The Bosch will work fine, if you are tight on cash. If the car is mint and a keeper for another decade, jsut get the best bougicords you can find.

Also, I would change ALL wires including coil wire all at once. Otherwise... you would revisit it soon.

My thoughts...
