The product is great, just trying to replace the plugs in a 2004 Highlander is what I would recommend being done by professionals. The back plugs are most difficult.

Comments about Pulstar Iridium Pulse Plug:

I have been performing basic repairs on my cars for more than a decade now (tune-ups, oil and flud changes, brakes, shocks, tie-rod ends, etc). This plug gave the same performance as any other good quality plug like denso or ngk iridiums I have installed in the past. Any new plug will will slightly improve performance. My 68k mile used NGK iridium gave me about 27 to 29 mpg on my 104 mile mostly highway trips in the last 2 months (8 trips). These have given me 28.3 and 27.9. Right in the middle of where the old NGKs were. Of course I have not driven these as much as the others, but I think these are in line with what I expected. I didn't believe that I was going to gain a 10% improvement as the marketing suggest, but then it's not a waste of money either. The price is similar to what NGKs or Denso or Bosch costs. By the way, I have tried Bosh platinums and iridiums in the past, and have nothing bad to say about their quality either. As always, iridium give you a longest life, platinums fall in the 50-60K range (can be used longer if you feel comfortable). Over the years, one thing I have learned is after a year or two, the space between the electrodes will expand, so if I re-set the gap, the performance is likely to improve but the difference is not huge. I give this a 3 star because, it does not live up to the advertising in my opinion, yet this is a satisfactory product in the sense that it does not under perform compared to other good quality plugs. therefore an average rating of 3 stars is justified in my opinion. By the way, expect these plugs to be not in stock and be prepared to receive it in a couple of days. Advance Auto is quick at shipping them so not a long wait, but 2-4 days is what you should be prepared for. The vehicle I tried these on is a 2009 Mitsubishi Outlander.

They just would not run correctly in my 03 Volvo V40, so I put regular plugs back in and it runs normally. I returned them. I had tried two gap recommendations, neither worked.

Read all the reviews. Looked like there might be a quality control problem. Thought i would take a chance with them on my wife's 97 Mercedes SL500 V8. Went out on a spin after install with my code reader that gives live data. At first was impressed. But then after 6 (SIX) miles, multi cylinder mis-fire. Plug 1,4,and 7 Failed. Limped back home to remove all 8. If you think I am going to replace JUST three plugs after 6 miles and not the rest, would You???? I would agree with some of the other reviews that these plug are just to fragile. Maybe they where damage in shipping, but I doubt that because they where packed between air pillows.

The theory behind these sounded believable, so I decided to plunk down the not insignificant sum of money to try them, upgrading from some NGK iridium IX's that had 60k plus miles on them. These definitely quickened the throttle response and the engine felt smoother at high rpm. As time went on, I noticed the idle was getting a little rough and the engine just didn't seem right. Later on the engine started misfiring substantially off idle. I pulled them with barely 10k miles on them and the gaps were way off. The iridium tips on the center electrodes were completely gone! They looked like old copper plugs living on borrowed time with a .080"+ gap and blunt center electrodes just about worn to the ceramic. It kind of makes sense to an extent, since the higher power, hotter spark is likely to sputter the electrodes quicker, but maybe the electrodes really weren't iridium, or some cheaper alloy. Either way, I am extremely disappointed with them, since they are advertised on Pulstar's site to last 100k plus miles like any other iridium plug, not that I would leave any spark plug in that long, but barely 10k is ridiculous. I considered sending them back to pulstar asking what gives, but just haven't gotten around to it. What are they going to do, give me a new set? Big whoop! I've got a new set of NGKs in now and these are just sitting on my desk making me wish I had my money back. They might be good for weekend racing where you're constantly checking and changing stuff like that out, and the benefit would be more worth it, but I just don't have money to throw away on expensive sparkplugs twice a year. Maybe I just got a dud and it would be worth getting them replaced, but...

Car is a 1987 Porsche 924S, 2.5L inline 4 cyl. I just run a MSD blaster 2 coil driven off the factory ignition controller, and it's a pretty tame light performance upgrade compared to other high energy systems out there, so I doubt that has much to do with it. Car otherwise always runs in top condition, as can be seen on the plug in my picture.

I did not see where they sell 8 of these at a time so I had to buy 8 singles. Each one had a different electrode height. They varied far and wide. I sent the mfgr. an email and though they acknowledged my email, they did not respond. I tried installing them anyway, and sure enough, the car misfired. Having read about how 50% of Pulstar's plugs fail or damage cars, I also bought 8 new double platinum (from a different mfg)for back up.
The other mfgrs plugs made the engine zip up immediately, and now I am smooth sailing.

I gapped these to my 03 Volvo V40's specs 0.031", and unplugged the battery and plugged it back in as recommended. It mis-fired constantly and I could barely keep the engine running. I re-gapped to 0.25 as the plug instructions said, still no luck, although slightly better but still terrible. So after half a day trying to make them work, I'm returning them. I put some cheap plugs in and it works great so I don't know if I did something wrong, or my Volvo is too finicky. It was a very bad experience.

This is my second set of Pulstar plugs. I tried another set in 2007 and as an early adopter, they let me down. I decided to try again and they had improved their instructions to resolve the issues that arose in my first try.
