What I don't understand is APR has listed a 2 step colder plug as a recommendation for their stage 1 ECU software. They never did that in the past, in fact Arin used to say just regap STOCK spark plugs with stage 1. I think it's a bad recommendation for them to suggest 9's for stage 1.
I also switched from RS7 to Ruths. Ruths work for me and they are relatively cheap. I've gone through 4 sets now (all looked great when I pulled them) and no problems.
For what reason though? The NGK RS7's can be had from FCP with a lifetime warranty (essentially making them free after the first set). I also ran Ruths for 10k on my stage 2 set up without an issue, and the recent RS7 tip failures has be considering switching back to the Ruths for my is38 GTI setup.
Variety is the spice of life basically....just like to try differnet things on my car.
So far so good - I beat on it hard yesterday and no drama.
The tip failures were always confined to the Beru version of the RS7 I thought? Havne't heard of the NGK having issues? Sure, you can FCP Euro them and get a few sets for free over your car's life, I'm not too worried about $40 from Rockauto to try them out...they could be better! I've tired them all at this point, stock, Denso IKH24, NGK RS7, and now the Ruths.
Check out this thread.
Agreed, has to be a type/mistake. Uni calls for stock plugs/stock gap on their tunes but they do run less boost than APR.
My take - improperty gapped and over-run in terms of miles/time. So many run these plugs with no drama.
Agreed.
It most certainly has been happening to the NGK RS7 (91006) as of late. Now all of those examples are ones I've seen on the EQT FB page which in my opinion as a rule, is a less experienced user base than this forum. There's no telling how many miles they are actually being run, gapping technique, etc. but nonetheless, tips are still breaking which really shouldn't happen unless the owner is being completely negligent in keeping up with the maintenance.
