well don't know why, but i decided to change my plugs today.

i went from it-20 to it-22's since i'm going to a 6lber

took 2 1/2 hours, thats super fast for me

only problem i ran into was #7 and the fuel regulator, since i didn't have a 1/4 wobbly, but i finally got it. also no anti-seize, because sal advised not to use it, i get a bad feeling in my stomach from this, but oh well, if thats what the big guy recommends.

also, my it-20's were in prefect shape after 18K miles of use

 

You dont need the Anit-Junk....

I have changed plugs 5 times already with no issues. I like to be safe.

 

I used anti-seize on mine the first time. When I checked them a few months later I had 3 loose. Since that time I have not used anti-seize against my better judgement and have had no loose plugs. A real plus is I haven't pulled out the threads yet either.

 

I have changed my plugs about 4 times now since Feb. I have not used the anti sieze either and have not found a loose plug yet either.


Rocks

 

I've read that anti-seize can ruin the O2 sensors. Is that correct or were they .

 

you need never seize if your not going to change your plugs but once every two to three years (atleast i think its a good idea)
if you pull plugs atleast once a year if not more prob ok not to use it but i always thought it was a good idea even more so with alu heads

why would it affect the o 2's not like your jaming a can of the stuff in the cylinder or in the exhaust???????
