Well, that is what to do AFTER you get them out, my problem is that I can't get them OUT.
They just spin and spin, no matter which way you turn them.
I have started saving for a JDM rebuilt motor, street ported of course.

when you get the stripped plug out simply put a CLEAN rag in the whole, then a simple re-tap with the right thread and you're golden. vacuum out the whole, remove the rag - fresh plus, go for a ride
When it was time to tune up last year we put Denso's in the car (our parts place was out of stock on NGK's!!) and they seem to work fine...I'll go back to NGK's this time though - i've been told not to use a stock plug since the AF mixture on my car is leaned out quite a bit (S4 NA). My EGT's are a solid 820-840 depending on outside temps at WOT but which do I run, All leading or all trailing (I forget). Should I run a stage colder as well???

With the stripped hole......get the old ones out....then when you tap the hold take axle grease and coat the tap with it....if you go slow and don't create a lot of heat all metal shavings should stick to the grease on the tap. After done taping clean carefully with a rag.

Also on the cost of the plugs.....I operate an auto parts store....the average price I sell them for is around 7 or 8 dollars a piece for NGK's. They are not popular....and the only reason I keep a set in stock is for me and others that come to my store because of me being a rxer owner.
