Hi all. Glad to seethe forum is back up.. in the downtime I found the facebook site and came across a post asking for spark plugs for  uilt 2.0 engines..  the factory plugs are autolite 42 or motorcraft 420.  And for higher compression, higher revs colder plugs like BF 32 were  used in days past. But alas all the info I have found indicates that the 32 range plugs are no longer made

Most parts stores substitute 42 range plugs which are "supposed" to be replacements but are too hot.  After a lot of research I found that autolite makes a plug   umbered 124 which is equivalent to a BF22 cold plug.  .it isnt a projected tip but runs a lot better than the 42 range.  My car is stock with 8.1 compression and with the 124 plugs gets about 500 rpm more than with the 42 range.
The 42 range plugs run white, the 124s run grey, and ive run them 5000 miles around town in dallas winter..but for the price you can afford to replace  .them once a month if they foul....autozo ne stocks the 124 for $.75 each.  They are not resistors and prolly need resistor wires..

Just some info
