i am pretty mechanically inclined, however i will be swapping my plugs out in alabama and have no way of getting replacement parts if i **** something up. YES I HAVE SEARCHED, but i didnt find any info on swapping them out. can someone give me a real quick once over on the steps to do it? i dont want to be wasting my time and risking breaking parts i cant replace doing stuff i dont need to be doing. i have a 12 hour drive to TX on thursday and would REALLY like to get them done before the drive as the ones in there are the ones that came with the swap 3 years ago. i JUST got it from the shop 2-3 days ago, the previous owner is the a$$ that didnt swap them, so dont flame on me, lol. all help is GREATLY appreciated!

i know that, but i have never taken anything off of the motor, i assume i have to take the intake pipe off, and the cover for the plugs, but i dont know whats under it.....nothing to worry about really?

same way you remove the parts you put it back the same way under the cover are the coil packs you pull them out one by one get a long extension and pull the spark plugs out...Very easy

ok, i have done CP's before on a galant, do they go don into the head, or are there wires? should i replace the wires same time, and if so can i get those from the parts store too or must i order them?

dude, there is no wires?...its coil packs directly above the sparkplug, just take the cover off and it will be self explanitory. you will have to unplug the coils, but they are all the perfect length so you can not get then crossed up.....hope this helps

easy way to do it. Look at the mounting brackets for the coil packs. 3 bolts. Unscrew them and it will take off all the coilpacks at 1 time instead of individually doing them. Pull the spark plugs then REVERSE! Ensure they seat properly(coil packs)

It should take about 15 min or less to change plugs on an RB

not to be confused with my 2JZ that takes about 2-3 hours if you have done it before.. *rolls eyes*

Like everybody said, remove intake pipe (cross-tube), un-hook wires from igniter, remove coil-pack cover plate, remove coil-pack harness, remove 3 (12 or 14mm?) bolts that hold coil-pack brackets in, remove plugs. Re-installation is opposite of removal.
