pnelego Posted May 22, 2017 Share Posted May 22, 2017 Hi! So I was planning on doing a tune up on my vehicle in order to rectify any issues that may (or may not) arise on a small road trip. I purchased some NGK 7092 Platinum Alloys that (hear me out) didn't come pre-gapped. Despite my struggles to find gap information in my owners manual, I'm left seeking answers. So if anyone has the plug gaps for my car, I would be obliged if you could share them. Note: I find it funny that I presumptuously added "Subaru" to the title of this thread. After noticing it, I'm going to leave it in just because of it's redundancy. Link to comment Share on other sites More sharing options...
RumbleRumble Posted May 23, 2017 Share Posted May 23, 2017 BKR6E-11 (NGK) (OEM FACTORY PLUGS) also goes by part number #2756 return the ones you have buy the ones above. They came in the car when brand new, they cost 10$ for the set and come pre gapped. Replace them every 30,000 miles. Link to comment Share on other sites More sharing options...
pnelego Posted May 24, 2017 Author Share Posted May 24, 2017 I talked with a technician here locally; they said to gap them at .035-0.037. The hottest plug was sitting at 55 thou on cylinder 4 with my last set. Granted the toastiness of that plug isn't a dramatic difference between all the plugs, only +- 5 thou. But for 30,000 miles on the last set, I have no complaints. Link to comment Share on other sites More sharing options...
RumbleRumble Posted May 24, 2017 Share Posted May 24, 2017 I'm sure it's fine but you don't want the plug to be too hot and melt that piston top. I'm just anal about using stuff that are OEM from the factory. Except subaru oil. Link to comment Share on other sites More sharing options...
pnelego Posted May 24, 2017 Author Share Posted May 24, 2017 No problem man, I'll let you know how it works out. So far so good as of right now, I'm keeping a really close eye on the plugs. I'll have it running for quite a while tomorrow. Link to comment Share on other sites More sharing options...
Brisky86 Posted May 25, 2017 Share Posted May 25, 2017 I also run the NGK plugs that RumbleRumble mentioned. Though I prefer to get the Iridium plugs so that they will last WAAY longer than 30,000 miles. I will likely check them closer to 50,000 - 100,000 miles. Here is what I bought in case you ever want to get them off the web.

pnelego Posted May 26, 2017 Author Share Posted May 26, 2017 So after about 30 cycles with my current setup, I pulled them real quick to check how toasty they were getting. After setting them originally to .035-0.037, all cylinders were happily sitting at 0.037. Unfortunately after 150,000 miles, my valve cover gaskets gave up the ghost, but that's another thread for another day. Link to comment Share on other sites More sharing options...
RumbleRumble Posted May 26, 2017 Share Posted May 26, 2017 VCG are easy to do. Go with OEM brands though. They are pretty important. Link to comment Share on other sites More sharing options...
pnelego Posted May 27, 2017 Author Share Posted May 27, 2017 That's what I heard although I have heard that the cleanliness of the gasket surfaces are tempramental and a prone to leak. Link to comment Share on other sites More sharing options...
RumbleRumble Posted May 27, 2017 Share Posted May 27, 2017 spark plug grommets also dry out pretty fast on aftermarket ones Link to comment Share on other sites More sharing options...
