Hydra what's the deal with these (I believe they're called) pulstar plugs i've been seing advertised lately?

 

According to Horse Power TV they used a OEM replacement plug and NOT OEM!

And according to the dyno this is only I think 9 hp difference. They claim 6% better fuel economy due to utilizing full fuel and air combustion. But again this is compared to NON OEM replacement!

In my years and expertise this can be created by utilizing a performance ignition and utilizing it right! By looking at this I would be very concerned!!!! This is not a usual spark so I would think of it as being like a plasma and grounding out through the piston creating a HUGE problem considering that the ground would hit the cylinder walls scaring them and pulsate into the combustion chamber into the heads. I see nothing but problems here in a short to long run, I would back up on this one! It sounds like a way to sell a $9.99 plug!

 

Hydra, Mean, anyone:

I have had no indications with the Autolite Coppers, and is running good, but to be honest I do not have $4-5 for a new engine if there is damage. With that said, I plan on switching to Champion, and ironically I have a road trip to Indy this weekend to get a good road trip.

Is there any special type Champions to use? or just regular? I looed into the iridiums but on the AutoZone site, they are labeled Platinum, and look very much Bosch Platinum +4 which if the regular platinums don't work in the 4.7 then I would be highly skeptical of +4's is my logic correct? (FINALLY) Would Champion Coppers work or do they even make them?

As a side note, I have been getting a M.I.L lately it comes back with the same code everytime P0456 EVAP Control system very small leak detected. I had figured it was associated with possibly overfilling fuel tank, but after this thread, I am starting to figure it might be associated with these plugs. Am I reading into this too much? I won't dispute switching plugs, but do you think these might be related?

Also on this subject, is there anything I can do to clean any possible carbon buildup in the engine, other than the old fashioned high speed way?

Thanks,

Steve

 

Champion Coppers will do fine as they are OEM. I prefer the Champion Truck Plug but they are getting hard to find. NAPA still sells them.

Champion Iridium Plugs are very expensive but through testing so far they have been working. The testing has been going on with the 5.9L tho.

The P0456 could be the gas cap not sealing properly and therefore needs replaced.

As for carbon. I don't like fuel additives but if you want to use something may I suggest Sea Foam in the fuel tank. You can also try distiled water sprayed into the TB with a sprayer at about 2500 rpm. It dosen't take much!

 

I personally use xylene. it is a chemical found in many carb cleaners. Another Item used from time to time is B-12 chemtool. < that is some good stuff... but the xylenecome in a one gallon can and I only use 3oz. per every 5 gal of gas. Xylene cost me $13.65 @ sherman williams, B-12 chemtool cost about 2 bucks per container

Either one of these will do the job buy over time I spent less money usin Xylene.

 

I havent gotten to the B-12 or seafoam yet, but Plugs were changed today. I got 8 shiny new Champion Coppers intalled. I haven't noticed anything overly exciting yet, but today was just a local run, I will evaluate the mileage on the new plugs for my road trip this weekend. Indy, Shuster Road trip to Indy area, PM me if you want to catch a cup of coffee, finally put a face to the name.

A true cold air intake or ram air will get ya some power and mileage.

 

I just put 8 shiny new Champion Coppers in mine tonight.

Evidently, the plugs are one thing that's been neglected on my truck. On a whim, I measured the ones I took out... the one that was closest to spec was measuring at .064

I should notice a bit more fuel economy and power yes?

 

If anyone is going to have their plugs changed, I would recommend the Champion Iridium plugs. That pencil sharp iridium tungsten tip is nearly impossible to foul up. To this day, I have about 20k miles on them and they are still brand new. When I cold start my D, it only take a flick of the ignition switch to start up and the idling is much much smoother then the regular copper plugs I had before.

MPG remains about the same but I do notice a improvement on throttle response time.

These plugs are rated for 100k miles of life.

 

I question the Iridium plug if you install a MSD ignition?

I know this application fouls plugs due to increased voltage and heat. Coppers last me about 10k, and Trucks last me about 15k.
