There are a Few Threads Re-Garding Random Mis-Fires with the E-3 Spark Plugs.......The Vortec Engine's Run and Performance Better when A/C Delco Sparks Plugs are being Used......In Some cases Staying with Factory OEM Parts is the Way to Go.....and this is One of those Cases.

X2 on using Delco plugs, the E3's are not what you want unless you want problems. Think about this way, if they were that great all plugs would be designed that way.Adam
