Spark Plug Help!!!


I called a local performance shop for help on some colder plugs. I have 351w heads and the plugs that are in it Autolite 46's. They did a cross reference on the NGK's and they gave me a A6FS #2210. When I called the local parts store they said it crossed over to the Autolite 124 which is a stock plug with the 302 heads. Any help would be great.

Autolite makes a nice plug. When your running nitrous I constantly changed my plugs because I could never seem to have it tuned correctly. Run a few degress down from the autolite 124s.
Best way to find the rite plug. Is start with the 124s. Gap them and then review the plugs after spray.

The 124's will not work, they are to small the heads are off of a late 60's model Bronco.

The bigger ones I guess LOL. Hell I got what my app would take, it cost me $5.99/each and they work GREAT, ask Truck U. I would also go ahead and snag some Ford Racing 9mm wires too.
