should i run these or return for diff ones before i install them?
You could compare the price, and it might be worth while to exchange them for the stock Autolite.Might walk outta there and have some good spark plugs and some beer $$ ........YAY!!!!!!
let me tell you something, i used Mopar chamion copper plugs, and they worked way better than the E3's...i will from now on only use Mopar plugs in mine due to the difference in my ignition
Like I said before, the Mopar plugs are the same as Champions. RC12LC4 is the number. These are the same plugs that my truck left Saltillo with. Check the emissions label on yours for the correct plug # and gap. I got 8 at Advance Auto Parts for $15. My truck really likes them compared to the Autolite 3923s and Bosch +2 plugs. When I change my plenum gasket, I'm gonna switch to some NGK V-Power plugs.
Also, if your truck does not like the 3923s, try some Champion RC11YC plugs. They are the same (colder) heat range as the 3923s. I'm looking for an NGK cross refrence.
E3s work really well in small engines, though. Maybe its because of the different design of the electrode. I may try the E3 RC12YC equivilent small engine plugs against the automotive E3s. That would be a good dyno test!
