Plug gap

[risky]

I'm going to be installing New spark plugs this weekend Autolite xp104 but I don't know what gap to put them too. My mods are php intake spacer, k&n cai ,180 thermostat,93 octane Lidio tune, steeda pulleys and 4.10s. I'm also going to install oem c.o.p with a set of Granatelli HIGH OUTPUT Coil On Plug Connectors 4 Valve. Any advice word really be appreciated. Thank you

I believe the gap is .052 to .056.

ALWAYS gap plugs before you install them , except for iridium plugs.

I gap mine on the low side... in this case .052 so as the plugs wear they will still be in range.

Risky wouldn't autolight 103 work better with your tune? they are a step colder then 104. make sue when you change engine is cold my gap is 54

I was going to get the xp103 but I talked to Lidio and he said that with his tune I don't need colder plugs

Gapped my new plugs at .054 the happy medium with a little dab anti-seize on threads & some dielectric grease inside the connector boots.

Motor purrrrrrrrrrrrs & runs like a champ.
