Pulstar Iridium spark plug ok to use?

Pulstar Iridium spark plug
Need to know if the VX can handle a hot plug same for coils?
I am getting 13 mpg and would like to improve mpg so has anyone tried this plug or have any feedback as to max temp on head?

update
runs like brand new with these plugs

Features & Benefits
Ultra-high power spark plug replacement. With over 1,000,000 W of patented (13 issued patents) ignition power, the pulstar pulse plug creates a very precise, relative to timing, fast growing flame kernel (2X faster than spark plugs) that delivers improved performance and fuel economy while reducing emissions. The 0.5 mm fine wire iridium tip promotes reduced cycle to cycle variations in peak combustion pressure that results in improved throttle response and acceleration. The pulstar pulse plug has a lifetime warranty. Guaranteed• Pulsar has 10 times more peak power than a spark plug
• More horsepower
• Improve the performance of your vehicle
• Better than a spark plug

Sorry! More HP = Less MPG. That's the way the game is played. Simple. Also, anything but the OEM plug is thought to cause other problems. Talk to Merlin at St. Charles Isuzu to learn more.

Ya plugs isn't the problem.. 13 is in the norm.

Also, more power doesn't mean less gas milage always. Depends on many factors. My Mitsubishi Evo was getting 17mpg stock as an average.. now with 150 more hp over stock it gets 24 on average. Best is to have a tunable car and make the engine breath better. But ya the vx is fat and under powered so its going to drink. We get about 17 on hwy and 12 around town.

Nippon denso are the ones no kidding

Many think the NGK Platinum spark plugs are the best for our trucks. But there are a few brands mentioned in these threads:

.

On summer gas my wife and I average very close to 20 mpg, all stock '99 models. With winter gas we average 15 mpg. Fact of life winter gas gives less mileage.

As far as power and mpg is concerned, with normally aspirated engines, there is no way on earth with more hp you can get more mpg, all things being equal. It's against the laws of physics

Thanks for the awesome post but most post where made when there was nothing to compare to I have to say the pulstar are very interesting.

Also, to get better mileage plugs won't help.







Also, to fix mileage don't look to the plugs, rather clean or replace the fuel filter and/or oxygen sensors.

Agreed. It depends on the factors involved.

I once had a mid 80's Mustang GT with a stock engine that would get about 20 mpg Hwy. I swapped the motor for another one utilizing higher compression heads with an aftermarket high-performance valve train, a higher performance cam, high-performance intake manifold, after-market full length tube headers, and a block that had been bored over standard to accommodate high-performance pistons with custom Total Seal rings. The intake, heads, and headers were all smoothed and port-matched to improve flow efficiency. Altogether, I netted an increase of about 155 hp. The improved flow efficiency and power-to-weight ratio of the new engine in the same car meant that the new engine didn't have to work as hard and my Hwy mileage as a result went up from about 20 to 28-30.

Nobody has ever succeeded is adding horsepower to a VX engine and improving MPG...nobody!

LMAO, horsepower this vx is a monster when it comes to that maybe my problem it like a freaking corvette I just want to ride longer without seeing bj or Costco and there water down gas that was the problem solved now only go to Sunoco premium gas wow drive all week.


Now I really need someone to get on top of this I like to change spark plug to this but before I do so can the VX coils and engine handle a hot plug for long periods of driving?

Sadly,I don't think this VX is long for this world.

YES IT SAD TO SEE YOU DID NOT HAVE ANY Valuable INPUT TO ADD OUTSIDE A THREAT HI JACK.:flame::drama::ot::hj:

Try the pulstar plugs,it won't hurt anything.And more horses can mean more mpg per gallon as long as ur not heavy footed,imagine a 50cc engine in the vx,do u know how much gas that thing would eat trying to propell 5000 pounds down the road lmao.;eeky;

It seem to be a very interesting are far some feedback goes thanks for the input everyone I order them off advance auto parts website used code A123 and got them for $57.94 PLUS TAX local pick up.

Read up on these so-called law of physics. Many engine builders know that a more powerful engine is a more efficient one. By that, I mean more of the air/fuel mixture goes to making power and moving the vehicle.

There is a measure of efficiency (called volumetric efficiency -- VE) that is a measure of cylinder filling. (There is also a percentage loss of power thru the drivetrain -- which is unimportant and a constant for this discussion). Better VE means more power. And, it means better leverage to propel the car. The problem with more power is people mostly use it go accelerate faster and to "hotrod". The problem with your generalization is a more efficient motor can pull the vehicle with less "effort". If you succeed in making an engine more efficient, driving it the same will result in better MPG.

Newer E10 fuels make cars look worse though. And, they are. Alcohol fuels have less BTUs compared to gasoline. So, the dilution of gasoline with corn-fuels lower the BTU rating -- and it's power. It takes more E10 fuel to get the same amount of power as pure gasoline. So, engine efficiency is going down -- without even trying.

If, somehow, you can create a better burn and more heat, you will make more power. As such, you will make better use of the fuel you burn -- which ends up with a more efficient vehicle.

Whether you use that extra power for better MPG or more fun is up to you.

So we did the research and it has proven successful removed the Ngk R and replaced with new technology plugs and the engine purrs very quiet for a vx the exhaust has a more clean smell then before it night and day with changes already going for test drive.



I will post a u tube video and you decided for yourself also some pic of the removed NGK R in the next couple day.


:drool::fyi::driver::_wrench:

test drive was awesome the truck idle perfect i can not say enough about this plug. Never seen anything like it. Runs like brand new

I am going with Autolite "double platinum" APP3924 ; my millage sux; plugs got 30K on them, had my shop put in truck plugs, noticed it didn't idle to well on cold start up the other day and it never does that; so pep said to use double platinum was OEM, any advice on the procedure for removal/replayment without breaking anything appreciated!

Hey ultra also in Maryland glen burnie if ever in the are let me know. Also i have tried these plugs and yes they did make a big notice on epg.

Are you saying my horse should go to the gym ? :confused:

Nah i just messing with ya

You may want to get the OEM plugs as they last 100000 miles

Now in Towson thanks
the plug are perfect but each person has to find there own path as to what works for me these work perfect money well spent.

It's about time for me to replace plugs and I'm going to give these a shot.

I couldn't seem to find A123 on AAP website. Is that the correct code?

If you remove the old engine and replace with a newer higher powered more fuel efficient one. But we are talik using the same engine.

Ok so few years later and i find these plugs to be priceless.
