12 mm sparkplug thread stripped

[evo58]

whats the best solution??
TimeSert  OR Helicoil
i think both can be done without disassemble the head ( front )
let me know

Timesert will work better as you will be removing the sparkplug and re-installing new one`s every year. helicoils are not good for that application.

Time Sert ...

... with Helicoil you will have to break off the bottom tab that is used to instal it ... what will you do when the tab falls inside the cylinder upon removal?

Just my 2 cents.

so i going  to TimeSert,

The head should come off....to do the job properly.....and not only that....you will end up with different volumes for the CC level between both cylinders as well....so if you care about that some additional effort should be done.  Not to mention that the stripped threads may have left some debris on top of your piston.

Time Sert is definitely the way to go, no questions asked on that decision. 

Don't ask me how I know.

Swede,is a option but i think i go to TimeSert,
in the past, i fixed one cylinder stud from my STD case,
was a very nice and easy job,
so on the spt head i will use the same...
thanks for all
