Unhappy Spark plug electrode broke off in cylinder..

Replaced plugs last week with NGK ILFR7H. Today I got misfires in cylinder 2 and 4. Went to pull the plug in cylinder 2 and the metal piece that you bend to adjust gap width is gone. It must still be in the engine. What do I do? I haven't pulled the plug out of cylinder 4 yet but I'm praying its not broken off too. Am I fucked? Should I take the whole engine apart to look for it? I don't think I have the skill for that. Should I just replace the plug and forget it? I'm trying to fish it out with a magnet right now. FML I can't believe this is happening...

Never heard of that before! Are you sure itís broken off and not melted/burnt away? Are the plugs fakes maybe?

Spark plug electrode broke off in cylinder..

If itís in there it will fuck up the cylinder, and may not be magnetic!

Are they not the wrong plugs? I thought NGK were either PFR7S8EG (laser platinum) or BKR7EIX (iridium) for your car!

Yup, has happened before. Usually old plugs or incorrect gappage for stage of tune.

Yeah wrong plugs as far as I can make out! MK7! theyíre probably longer than spec and have made contact with the tops of the cylinders, the two that havenít been damaged are probably not in quite as tight as the other two that failed! And are a probably a minuscule distance from touching,

Yeah they're for the mk7 gti idk why I didn't notice that. I think I'm fucked I can't get that piece out with the magnetic pickup tool, much less all the other spark plugs. 3 came out fine but 1 and 4 are stuck... I loosened 4 as far as it could go but its still connected to something even though its wiggling while attached to the spark plug socket, but it just won't come out. I haven't messed with 1 because it would literally take a breaker bar to loosen it.. Suggestions?

Take a vacuum attachment and put a mcdonalds straw on the end. The rigidity and reduced diameter should be enough suction ao you can turn it if its wiggling

The reason you canít get the electrode out is because it is now embedded in the cylinder probably! Plug 4 is probably stuck on the plugs compression ring which has probably come away from the plug and is stuck to the head, keep trying and itíll probably come out but may leave the ring stuck in place, not disastrous but also not ideal! Plug 1 may come out easier if the engine is hot, (hot air gun might do it) as you obviously canít run it.

Plug 1 is out, also broken electrode tip. Lots of tiny pieces of metal inside that I'm picking up with the magnet. Must be the tip when it shattered. Still can't get plug 4 out..

Best bet is to get a borescope from home depot and get a look inside. The one I bought has a mirror, flashlight and a magnetic attachment. Will hopefully give you a better look at what you're dealing with.

I'm seeing this as a plug for 2006 Mitsubishi's

Also, a quick Amazon search says this does not fit a GTI
