What is the spark plug torque for a 94 dodge spirit 2.5?

Answer 1

The 2.5 liter four cylinder engine in Dodge Spirits and Plymouth Acclaims uses the then very common Champion N12Y or N12YC spark plugs (or their equivalents in any other brand. Those plugs require 20 lb Ft of torque and nothing more (the cylinder head is made of Aluminum, so try to use a torque Wrench to avoid over-torquing and possibly stripping a thread! Plug gap is 0.035" or 35 mils. (0.9 mm). Turbo engines MUST NOT use Platinum tipped spark plugs, since their very thin electrodes cannot conduct away the heat produced by those more powerful engines, and can produce preignition in those engine versions, which should use only Standard type plugs. Non-Turbo engines can use Platinum electrode plugs with no problem, which tend to last much more time between plug changes. Amclaussen.
