Pulsar Spark plugs?
#35
Pulstar does say 50k miles for their plugs lifespan. We haven't done any long-term testing yet, but I'm starting to pile the miles onto my G35 now that the spring is here, so will get you guys some mileage data, plus we're testing the plugs on 4-5 different motors (Honda K24 and H22, Nissan VQ and SR20DET, Toyota 2JZ, and Mitsu 4G63), so I'll be able to give y'all some more feedback pretty soon. We just tested a set on a '05 Honda S2000 and picked up 3-4whp across the rev range, which on a highly tuned engine like that ain't too shabby IMO.

These Plugs Are Scaring Me!
I first heard of these plugs from a guy at work. He was going on how great they were in his truck. I did my research and bought a set. Put them in last weekend and WOW! They woke up all my modes and I could feel the difference. From 2000 - 4000 RPM the car is more awake with lots of responce. I was very impressed! The care seems to shift smoother and just be more awake.
So I go to work today only to hear that my friend broke down and to be towed! After putting his truck on the reader it showed 3 spark plugs as errors. They pulled his plugs and put stock back. The 3 plugs had the electodes burned off level with the ceramic after 6000Km. What the hell!I asked him if he gapped them right. He said he put them all at .042 as recommended. I set mine at .044 as Pulstar recommends. I was wondering why all my stock plugs from the factory were all set around .035? Anyway if anyone has heard of anyone else having problems please post. I am thinking of pulling them out until I have a answer to why his failed.

I put Pulsestars in my 04 Sedan 6MT. I felt happy with what seemed like a power increase and crisper response. I did not dyno (never have).
I could easily believe they are snake oil, but I tried them and I like them. I think I have about 10k miles on them, no probs.
I did not get an improvement in mpg still get the 15-16 city adn 23 or so highway I've always gotten.

Still reading all the entries in this thread, glad I found such a thorough conversation about these babies!
ps—IDK how these can be snake oil when the technology and science behind them is completely feasible and in use in other products that involve high-discharge instruments that demand consistent high output. Just think about your camera flash. Small input, high discharge.

only issue i see is if you have a weak spark, the capacitors may never charge enough to discharge.
(if i remember my physics classes right, a capacitor only releases it's charge once it reaches a certain point, hence it's use as a filter or as part of a timing device (in conjunction with a resistor). the discharge period of a capacitor is very quick, and varies with construction and make up, but, i would say, in any case faster than a coil discharge. in theory it works, with a small retard in timing but a potentially stronger spark, which may arrive at the same time as the peak spark before hand. whether it makes a noticable difference or not, i don't know, but i would suspect more gains in small engines with coil-only ignitions)
