Installing oem replaacement plugs balt sstc. Other than a. Cooled engine block any other tips or advice for installation?? Someone said something concerning if plugs have a gasket seat or taper seat.... It will affect the amount of rachet turn after finger tightened. Thank you

 

Nope, cool engine is all. torque to I think its only like 15ftlbs or so. Make sure you use a spark plug socket, I remember seeing someone break the plastic and fell into the engine.

 

Lefty loosey, righty tightey.

 

Just curious..how many miles on current plugs?
Also, could you post some pics of THOSE here when you get em out?
As far as tightening...15 lbs..that's about 1/8 turn after you first made *hand tight* with the wrench.

 

Lol, that was me...twice. Except, I did use a spark plug socket the second time and it happened again so...yeah. Changed a million plugs and have never seen anything like it. I've changed the plugs since then and it didn't happen again. Just very weird...

 

Make sure you use some sort of anti seize like Kopr Kote

 

I just got my stock plugs (41-108 AC Delco) from Rock Auto. They were 5.15 ea and I ordered 4

I got a box of EIGHT. Gotta love it!

 

Do they have the #5476 on the metal above the taper, Ron?

 

These are AC Delco. It does have a stamp on the neck says Japan and this #ILTR5D (which is NGK I assume).
No reference to NGK or 5476. I assume they're the same though.

Someone said to never use anti seize when puttin in sstc plugs??!! Which is it...

 

I installed mine when motor was warm, like 115 degrees. Hopefully I'm good. They came out fine and went in fine.

 

Whoa, holy necro thread.
