Pulstar Iridium spark plug ok to use?

[WILLY]

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.

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.

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

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.

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.

[Gussie2000]

Ya plugs isn't the problem.. 13 is in the norm.
. But ya the vx is fat and under powered.

Are you saying my horse should go to the gym ?

Nah i just messing with ya

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

[UltrAsOniC]

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.
