Does anyone what the plug gap for my 02 Legacy L 2.5l should be (using OEM NGK plugs)? I cannot find a reference to this in my manual. Also, is there a recommended torque setting when tightening? Thanks in advance for any responses.

not sure if it's the same but on my 94 leg,it's .44(i believe,or +/- 1)

don't think you really need to torque them down,tighten till the seals seat then1/4-1/2 turn after.that's the most i know,everything else i ask my mech about to be sure.

Correct spark plug gap is shown on the Federal Emissions decal applied to the underside of the hood.

Don't forget anti-seize goop on the plug threads and di-electric grease on the porcelain part of the plug, it's worth the trouble to avoid other problems later.

Spark plug tightening torque: 13-17 ft/lbs
Spark plug gap: 1.0-1.1mm or .039-.043in

Thanks for the replies! Job was fairly easy, after removing snorkel to air cleaner, battery and washer reservoir to gain access to plug wires. Used a standard spark plug socket with 10" extension on passanger side and 6" & 3" extension on the driver's side. Did not need an elbow, like the endwrech procedure said.
