so i have been wanting to make a diy for awhile now. so here it is. i will put in the gap specs later as i remember or get them.
the usual disclaimer, i'm not responsible for any problems or wrongful installation. the engine can be hot if you just drove it. be careful about hot parts...
to start, you need a 10mm socket, 5/8" spark plug socket, an extension, a ratchet, anti-sieze, spark plug gap tool, and of course spark plugs.
get a socket with the rubber inside to hold plug. it will make life so much easier.
when i wrote this, i could not find very many options for plugs. i went with the autolite. i would have chosen ngk if i had a cross referance. stock plugs are NGK IR SILZKr68(mine were) i would go with iridium as they will last longer. platinum and copper will work but dont expect to get 100k miles out of them. dont be afraid to spend $8 a plug. its going to stay in there for awhile.
gapping the plug
i never trust "these are pre-gapped". Think about it, those plug boxes are being thrown around, dropped, messed with. so i ALWAYS check them. BE CAREFUL ABOUT DAMAGING THE FINE WIRE ON PLUG.
slide into spark plug to check
put like this and slightly twist to increase gap
pull cover off of engine. just pull straight off.
you will see this
use 10mm socket to remove bolts that hold the coils on
then grab coil and pull up(mine was very warm as i just drove car)
use ratchet,plug socket, and extension to remove old plugs
should look like this
take new plug and add a little anti-seize to threads, - Optional only needed for other brands, NGK plugs don't need anti-seize
put plug into the socket and put back down spark plug hole. then HAND TIGHTEN(this avoids cross threadding) until it stops. then use ratchet to tighten another 1/4-1/2 a turn to seat gasket.
put coil back on and tighten 10mm bolt until snug.
the driver-side-most plug will be hard to get to. to make it easy disconnect this plug, reattach once done
to put cover back on line up this point
close hood, then you are done!!
I know many can change a spark plug, but some may have not. so i hope this helps someone. any input or questions, please ask as this is my first tutorial.
this was done on a 2012 veloster with 120k miles.
