well they look the part ...  but there is an oddity.  It appears they are pre-gapped to .028/.029 ?    I cannot find my feeler gauge but my old wire guage .030 wont pass,  it is a hard no on all 6 plugs. 

part number is below and does not have any good details from the googlez

I've been running mine at .026 for the last year. I think you would be fine running those.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

My ceramic has a 3 on the end of it ( CYFS092YPT3 ) .  Wonder if that means revision 3 of the ceramic tip,  mine is the new ''long tapered'' type.

I did not. If we're being honest, my add generally doesn't allow me to retain anything past the first sentence of any post so I assumed your hangup was more gap based.

Update,  I do NOT like these plugs.   I have lost 4 tenths of a second of my 0-60 ... way way not happy.

Dropped from a repeatable 4.4 to a 4.8 ... super pissed since they cost a bunch

I switched to the M-12405-35T plugs about a month ago. They seem to be OK.

I failed to update the thread,  my bad.  A reset seems to have solved it... but i'm baffled and still kinda annoyed that changing plugs had such an effect ..
