So after running some NGK copper 7's (4644) for some time, this set lasted about 1000 miles before they started stuttering under boost. I just put some Iridium 8's in, not only does it start, idle and drive better, it feels much better I to boost too.

So just a suggestion when your shopping for plugs to go with them coils. NGK 2668. I found 2 boxes on EBay for 15 A box.

You'll thank me later when you're putting it back together and you need to "see" where something goes that the cave painting camera didn't show ;)

Or even just after it's back together and you're reminiscing about the work you've done and can look at pictures that don't look like they've been taken through a peanut butter filter!

Damn. That is exactly what happened with me. The coppers were great for a bit over 1000 miles then they started missing. I am going to switch to the iridiums and see if that helps. What gap are you running?

Signature changed to make Bird happy.

I had issues with IR's glowplugging at high boost/rpm ...

I remember you saying that so I've been keeping that in mind... What ignitor /coils/boost/rpm were you running?? For reference



I'm planning on (after the turbo block is built) pumping the boost and rpms a bit but I am hearing more and more about extremely short life on coppers with other coils.. Could that be due to too long of dwell??

Update on this. I was still getting some breakup in higher boost, ended up putting new springs in the coils, the spark springs between the coil and plug. My stutter is gone and on a repull tonight can hit my 25psi I dynoed at. Maybe keep a spare setup in the tool box. There cheap at 3.00 for the spring/boost setup.

I've got dwell down to 3.1ms too.

Hey so I was trying to find some info on my turbo but I can't read Portuguese :p
At least I think that's what language it's in

Master power
Part number: 810031-096
Model: s.70

The only thing I could find in English was a short list and didn't include my turbo:-\
