Well one of my spark plugs blew out the other day and it messed up the threads where the spark plug screws in to...What type of rethreader should I use to fix this?
Thank You!

 

Helicoil is common, I had a spark plug do this a while back and I took it into a shop to have the job done for me. They put in a solid insert into my head, instead of a helicoil, and it works great. I just took the car to the track this weekend, and on top of that its been in there for a good three months no problems.

 

alright great thanks! but im probably just gonna do it myself.

also what is the size of the sparkplug hole that i will need to buy?

 

I know I saw helicoils and inserts at autozone a while back, so I think you can get them there. I am unsure of the specific size we need for the LSJ, but that could be a starting point (autozone, o'reilly, pep boys, etc)

 

At most parts stores they have a spark plug rethreader tool.(its like $4's)
