Hello all!!

I bought new Champion spark plugs and I started to replace them when I noticed the new ones are very different than whats in there now.

I have in the engine Champion rc12yc, the replacements are rc12lc4 and are not only longer but the proceline protudes out further. Can someone tell me whats going on??


Thanks

Chris

 

This is what I get for slapping the motor in and not replacing the plugs while it was out. I have 3 of the above mentioned plugs plus one Bosch Platinum and two that are currently sitting in penitrant(dont know what they may be?)because they appear to be frozen to the motor. And I should know by now about cutting corners.....jeesh!!!

Well here I am having a conversation with myself..uh oh.

N E way I got the other two spark plugs out and they were both Champion. Truck idles better and is a bit more responsive. My plan next is wires, cap and rotor.

SO back to my first question, does n e one know what the differences are between the plugs I pulled out and the ones I put in? Think it will have any effect on milage etc?

Thanks!

Chris

 

The RC12LC4 is the correct plug for your truck (well, I assume it is, depending on the year and engine). It has a projected nose; this type of plug was specified by Chrysler.

Thank you sir!
