yeah what's the word on these plugs? I'm thinking about buying them

 

Just heard on another forum some guy came back with these b/c of a misfire. They pulled plugs and one was dead. It rattled inside when shooked. This is the second time I've heard of this condition happening.

Think I'll pass on these personally.

 

I installed the pulstar plugs about 3 monthes ago. I dont really feel any "11" hp gain and "8" fpt. I do think the car revs a little faster besides that I think they are b.s

 

I remember when nology plug wires came out and i bought them for my vr6 gti... the damn car started misfiring turns out one of the wires had a crazy amount os resistence in it... Id stay away from anything like this

 

NGK Iridiums FTW!

 

I had them on my car for like three months and then my engine light came on. I don't know what happened but I had to put the stock ones back on. I didn't feel any difference in horse porwer because i bought my car used and it already had the ngk iridium but they did save me a lot of gas.

 

(Thread officially re-opened)...hmm, taking a chance on damaging my Zed's engine PLUS paying a lot for them thingies? I don't think so! I'll just give 'em some time to prove themselves.

 

Any special reason why? By doing so, you just give Pulstar more publicity, and and more people might try this crappy product.

 

LOL!! Know someone running these now. Guess so far so good, but I'm not sold yet (even if no issues) with price and only 50K mi life.

 

Tried these 2 or 3 months ago.
Pros
MPG + 1 to 2
Acceleration + 3 to 4 MPH over defined distance (NOT formal timing simply a set distance I use as reference)

Cons
One plug self destructed, destroyed the center electrode
Wasted time to R & R all the plugs

Plug vendor returned all $ including shipping charges and provided call tag for return shipping of plugs

Plug manufacturer paid for a compression test at facility of my choosing.
Manufacturer stated issue sourced at one of the two plants manufacturing the plugs.

End result, engine OK no damage

Opinion, if a company has quality control that is this poor I do not need to use their product.

 

Dear Dave: No, no particular reason...I AM a member of the forum, so I just did! I keep getting mixed feedback regarding them doohickeys, so I try to find out the facts on 'em from users in the forum---you KNOW the manufacturer's gonna say all kinda good things about their product!

 

Funny that just happened to me. The plug from cyl 4 failed no more electrode. I just finished replacing them. I am going to attempt to get hold of the company and get a refund. I had them on my car for less than 5k.

 

That would be me…lol

Had them on for 3k miles now, no problem what so ever. I would have liked to dyno them with 5 pulls when fresh, along with stock plugs and iridium. Just could not line up the dyno. I have been working with a tribologist (oil expert) Terry Dyson on my freshly built engine. The used oil analysis (UOA) and his tuning tips has benefited engine efficiency.

We will see how they fair on the next analysis coming up soon. His analysis takes into account the nitration readings (how well it’s firing). I would not trust any plug to perform at peak after 35k miles. So mileage and mpg is of no concern for me. I am looking for efficiency and performance.

 

I have them in my titan. I have see tons of these fail or break while being installed. I talked to 2 guys last week that were running them they each had failures and went back to stock I have yet to have any issues. That all being said I wouldn't put them in my G if you payed me and the only reason they are still in my Titan is because I am to lazy to change them out.

 

Anyone other than me wondering why Sandia National Labs would have anything to do with a spark plug in a car?

Maybe they stem further in their endeavors than I'm aware of but having worked closely with Sandia before in a different sense I really wouldn't trust anything they had a part in. All their stuff falls apart.

 

Enough speculation! Bottomline: Get gold ones OR iridium ones OR platinum ones, but NOT those "Pulstars". To pay so much $$ for something that has, at best, produced mixed results wouldn't be wise, I gather; so I'm staying with gold ones (Champion's), which yield two weeks out of a tankful in "normal" driving.
