- AUTOLITE (BUT WON'T) SPARK PLUGS -​

I am slowly moving away from autolite to ngk on the shop built engines due to having a better heat range selection with the ngk’s as well as having some brand new autolites not firing from the git go.

The autolites have been coming from both mexico and china but it is the china made autolite spark plugs that i have had trouble with. It seems to be potluck at the parts store on which country of origin the autolite spark plugs are from. I now do a mandatory ohm check on the new spark plugs before installing them.

LACK OF CAPITALS HAS SOMETHING TO DO WITH MY BROWSER NOT WANTING TO CAROUSE PROPERLY ON THE BOARD.

You need (IMO) NGK plugs. What year LINCOLN and Country of Residence?
 
NGK PARTS FINDER SHOWS -

https://ngksparkplugs.com/en/part-finder

1956/67 LINC 368CI -

V-PWR WR5 STOCK NO. 2438 - OE EQUIVALENT

It also shows an IRIDIUM PLUG but IMO would be a waste of money unless you had a HOT ELECTRONIC IGNITION CONVERSION.

Maybe check there for availability and if not get back and will try to find an international shipper.

manufacturing location of autolite spark plugs

autolite spark plugs are manufactured by fram group, a company that also offers oil, air, and fuel filters, as well as pcv valves and transmission modulators. Fram group is a subsidiary of the rank group, a new zealand-based private investment company owned by graeme hart, the richest person in new zealand.

The manufacturing location of autolite spark plugs depends on the product line they are producing and the market demand they want to meet. But most of the manufacturing of autolite spark plugs takes place in china, where fram group operations llc imports from shanghai sweet auto parts coltd in china through the port of oakland.[2]

some of the autolite spark plugs are also made in the us, in fram group’s factories in greenville, ohio, and albion, illinois.
