I installed the IK-22's at 700 miles at a Randy Webb pulley party. He convinced me they are a good idea with a 15% pulley. Now the car has almost 17K miles. I checked the torque on the plugs at each 5K mile oil change. After installing the stock plugs. one thing that was immediately noticable, is how much easier the car starts and how much more smoothly it idles. Also, when taking off from a stop, the engine does not seem to have the momentary power lag it had with the IK-22's. I just figured this was 'normal', since the IK-22's were installed when the car was five days old, I had no basis for comparison. I can't discern any difference in power or how the car runs, other than what's mentioned above.
I'll leave the stock plugs in for now.

It's possible that after 17K miles, the IK22's were exhausted. There is a thread in the Drivetrain forum where people pulled their Densos and took photographs, and the conclusion was that the Denso iridium wore out quite fast (and are not rated 30K-100K miles, as some initial claims).

Just had the same think happen here - stock plugs
I just had the same thing happen to my MINI, in my case I had stock plugs anda 15% pulley - my theory is that over time the plug worked its way out and eventually blam! I don't think it blew out all at once.
I like the re-sleeve option, at the moment I am looking for something on the cheap side and a new head was NOT cheap (I had the same figures from the dealer as far as parts and labor cost). A performance head is appealing but if I can get away with a repair that saves $1k (or more) I can't ignore that as an option.

Well this just happen to me tonight on my way home. Plug #2 blow out. I had been getting a Code that was a Misfire but didn't get time to check the plugs before this happen.
I was running NGK plugs. I Don't remember the Model Number right now but it was the ones that run a little colder than stock. By the way the stock plugs are NGK. Well in my 04 there were. Anyway I'm off to try to fix this problem.

I have ran 25 ft lbs as per testing since I got my car.... I say as per testing cause... using the factory spec they would get loose.. then started cranking one lb at a time.... 25 has held.... even 40+ lbs of boost... they still didn't get loose!

Thanks Tüls
Wow 25 ft-lb is a lot of torque on an aluminum head.
Next time (soon) I check them and they move I'm pulling them to have a look. Then torque them to 22 ft-lb, I'm only making 16~17 lb. on full boost.
I was going by the Bently manual torque speck on a stone cold engine.
The NGK website recommends;

(Wow 25 ft-lb is a lot of torque.)
But then extreme conditions require extreme measures and I'm sure NGK published data on the conservative side.

Problem fixed. I went to Advance Auto Parts and picked up a Helicoil kit. The kit is call Save-A-Thread and the part number is 5334-14.
I put this helicoil in with out taking the head off. All I did was use a ShopVac and taped a small holes on to the shopvac and got all most all the metal pieces . The MINI is running great once again.

I had a 15% pulley and Alta cold intake done in 2005. Was advised to install colder plugs, so my tuner put in the IK22. These were in for 35-45k miles. Took in for oil, fluid service in 2008. Plugs changed to new IK22's. Oct. 2009, took off from a red light near work(after a 8 mile commute from home on the freeway). Heard a BANG, sucking sounds and all dash lites on. Was able to reinstall the plug (number 1), and drive home. Next am I re torqued all plugs to 21ft/lbs. Checked plugs every month (about 2k mi.). #1 seemed to always require about a 1/4 to 1/2 turn to torque to 21. All other plugs fine. June 1 I check the plugs. #1 just turns and will not tighten up. All other plugs fine. Take #2 plug and try to insert into #1 cyl. Just turns. Ordered a TimeSert and 2 inserts the next day. Called dealer and asked what the OEM plugs were. Was informed that they were NGK BKR6EQUP. Dealer quoted $24.99 ea. Called auto parts store, quoted $6.99 ea. My neighbor and I spent about an hour last Sunday, cut new threads, cut new seat, installed the TimeSert insert. Installed the NGK's watched as my neighbor's (Ford & Chevy guys) cringe as I torque the plugs down. So far, 125 miles on this repair, still a little gun-shy on full throttle except getting on the freeway, but so far so good. Gas mileage seems to have improved also. Total cost $220.00. Now the next question, Do I keep the MINI for another year (as I had planned) or trade now? BTW 78k miles on odo.
