Spark Plug Replacement
Hey everyone,
So this past weekend I replaced my belt, tensioner pulley and idler pulley and it sounds/idles so nice!
Decided to take out a spark plug to take a look at it and I decided to replace them. Bought some Iridium plugs and they are coming Wednesday.
Any tips? Particularly should I lube the new plugs before putting them Into the block?

For the cabin filter housing you first pop off the filter covers via a metal clip along one side that locks it down. Then there is a plastic piece in the metal which connects both halves of the housing together. I believe you lift a tab on the left side and slide it to the left. Then each half has 3 or 4 of these 13mm plastic nuts that you can turn approximately a 1/4 turn with a socket to release. Then they just pull off. once removed there is also a plastic housing that holds some wiring looms that go across the engine. They are held on to a metal sway bar with plastic rivets. You push the pin out of the center and pull the river out to remove those. 4 torx bolts hold the sway bar on top. I’m pretty sure you can find the procedure on YouTube.

Torque spec is printed on the sparkplug box, but I always seat then turn 1/4 (90 deg) more. Always have, always will. Never had a problem with it.
