Plugs

[Stangman]

So my dad called me and told me he bought me plugs to bring to reunion. I used auto lite 3924 but he boughtar3923-pk and xp 3923. Can I use these or should he send them back. Does anyone use these. I know the Xperia’s is a platinum plug I believe. I’m using a NGK bk6 or something like that now. I don’t know if it’s a colder plug.

A 3923 is a colder plug than a 3924.

I had some Ignition problems It was due to alternator wile I was trying to find out the problem I talked to my ignition manufacture I had never had any problems in the 4 years ive had my engine running but I never could find a non-resistor plug long story short I changed to ngk bcp6es plug with my bbm heads and it seems to like the non-resistor plug.
