Just to let everyone know, ALLDATA says 14ft lb on the plugs with 0.43 gap and 75 in-lb for the throttle body. If you guys remove the intake manifold 14 ft-lbs. 15-22 might be too much🫡

Thx! one revision/note...Factory service manual says 0.043 in, or 1.1mm gap on plugs. Don't use a round gapping tool to expand the gap per Denso. Quote: DO NOT LET THE PLIERS OR GAPPING TOOL TOUCH THE IRIDIUM CENTER ELECTRODE OR PORCELAIN.

My tires are completely dead because of the camber, when I lowered, the guy told me that it wasn't necessary align or anything but now I've to order new tires and I'm not sure if just an alingment will fix, some people told me something about check the toe, have you aligned yours? DO I need camber kit? Thanks man...
