hey,

just getting ready to order a whole slew of stuff for my long tubes... i've got the spark plugs but after searching i'm somewhat torn/confused. should i got with the .050 gaped TR55s or the .035 gapped TR5s. from what i've read there is equal pushing for both, which just makes it even more difficult for me to make a decision. this is a bolt on car, no SCing, or nitrous... (yet, if it makes a difference). thanks for your help

For a N/A bolt-on car you want the stock heat range (TR55 or equiv).
