I just wanted to know if the plugs come gaped or I have to do it myself.

 

I bought mine from oreillys already gapped.

 

the NGK plugs come gapped BUT twice in my lifetime- both on this board no less, I heard of 1 of 6 plugs being wrong
Most likely mishandled at some point as they come in a protective cardboard cap,,,but things do happen

If you dont own the right guage- just eyeball them- if all the same apply a very thin layer of plug anti-sieze ($1 pack is plenty for all), just on the 2-3 middle threads
Dont want any getting pushing inside the engine.
this stuff helps the new plugs go in easy and be able to remove in another 70k miles~

correct torque is important~~

 

the coils are to be handled like fragile glass that cost $50 each
set each down gently on a towel when removed, internal damage is easy and will make the car run funny

I always sugest seafoam the gas and intake vac port before new plugs- so they have a clean home to work in

 

Just replaced with NGK plugs and found this note in the Alldata manual which stated the following...

3. Do not adjust the gap (A) of iridium tip plugs;replace the spark plug if the gap is out of specification.

 

thats right- you cant use a normal plug gap tool to reset them- the electrode is super fine wire and should be at the correct gap
There is always margin built in too- gap spec may say .040-,045 and the plugs will be set .042--its so they work on many different cars

Like I said- if they are ok visually- meaning each looks horizontal on the end wire- they are set
