Delco and NGK iridium both work fine, I can not believe Champions or even Autolite wouldn't work virtually the same. Thoroughly disappointed that Engine Masters failed to include E3s in their spark plug thrash. alas
GM performance product plug wires (12495519) used to be the bargain of bargains, but have gone up quite a lot in price in the last couple of years and don't seem to be available anywhere. If I were doing mine at the moment, I'd get the SMP Blue Streak wires from Rock Auto. $84 plus shipping, 9MM with less than 15 ohms resistance and included heat boots.
