Only trust champion in my Mopars
I only use Champion spark plugs in my Mopars and always will. Great plug for a great price.

Don't Trust an On-Line Order
Made this an on-line order for four (4) spark plugs; waited about one hour and went to store for parts pick-up. They handed me a pack of the WRONG spark plugs. Waited until the guy actually found the correct ones, BUT they only had three (the on-line computer system said they had four.) Get this--since the order was "on line," it was not yet 'fully processed,' so the Parts Clerk was unable to re-write the order for 3 plugs, nor give me a credit. Waited in the store until the on-line order was FINALIZED. Wasted much time and after a while I said: "Look, just cancel the whole order, and I'll pay cash for the three plus you've got." This resulted in me LOOSING my cool 25% discount. What a colossal PITA!

Will this work on a 289 with hei ignition
Verified Reply - John the Car-Doc
Hi Ron! Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model, and engine size of the vehicle.
Is this compatible with champion UL-77V
Verified Reply - John the Car-Doc
No, Tony. This Champion Copper Plus Small Engine- Boxed - L77JC4 - Part # 821 does not replace the Champion Nickel Spark Plug - UL77V - Part # 831. However, we do offer the NGK OE Series Standard Nickel Spark Plug: Surface Discharge Tip Design, BUHXW-1 - Part # 5526 online. It replaces your Champion part # UL77V.
What Socket/Drive size do I need for this plug?
Verified Reply - Steve
Hi Amit, I'm glad to help you! This Champion Copper Plus Small Engine (Part # 868) will work fine with 13/16"- inch spark plug socket.
Can a RJ19LM spark plug be replaced with a Champion RC12YC
Verified Reply - Steve
No, Charles, this Champion Copper Plus Small Engine (Part # 868) is not equivalent for Champion RC12YC spark plug.
Why can't I order it now?
