Hey guys I'm at about 95k miles on my '04 monte supercharged and pretty sure the plugs' never been changed. I wanted to change them couple of years ago, but was told that the wires rip easy.

1) Has anyone with an L67, or L32 changed plugs and what kind of plugs did you use? Were they good?

2) And How do I go about with this "gap" I know it's between .57 to .60. But what do i do with that number, or what is it?

3) Any special tools needed, like a torque wrench?

More of a suspension component guy than an engine guy but any info i will appreciate.

 

Yea the wires rip easily, specially if you haven't changed em in so long man lol can't ever go wrong with ACDelco tho! The gap I would leave at .60... they sell a small tool at AutoZone to measure the plug gap. it's real cheap. As far as tools go, I found it very useful to rock the motor fwd to get to the rear plugs

 

Alright thanks 38 sspecial i'll give it a go.

 

No problem man good luck!

 

Always a good idea to get new wires with the new plugs.

As far as gap, go with .060, a little on the lower side won't hurt anything. .60 would be a pretty big gap

You don't need to torque them in, get them snug with a ratchet and then give them a bit more of a tug.

 

I have autolite 103 plugs in my Monte..

 

Did you notice any improvements with those and is your monte stock for the most part?

 

My monte is 2005 supercharged SS with a smaller pulley& cold air intake ,Power plog thats why I installed autolite 103 plugs .

 

All I have is a K&N air intake, and that's IT lol do you know if those would give me any issues since my monte is basically stock? Or would 104s be better?

 

Haha that's what I meant Enzo, didn't think anyone would catch that

If you're near stock I wouldn't worry too much about what plugs you should use but 103s are good and they wouldn't hurt as far as noticing a difference, you honestly can't tell lol
