Howdy all!

I have an 86 convertible -- converted back to carb.. blowthrough carb. Going turbo with 10psi. Any suggestions on what plugs to go with? I know the whole 'few steps colder' deal.. yada yada yada. But Ive had some serious issues with different brands here and there and was wondering if anyone had any kudos to give to a specific brand. Or hell any banishing of any specific brand as well.

Best Regards and keep On Boostin!

i've been running autolite 3923's (aluminum heads) gapped at .035" . They get the job done. I index them as well.

if you're using irons, get autolite 23's. Same as the stock plugs (25's), just 2 heat ranges colder. The 3923's have longer threads meant for aluminum heads.
