I have gone over the dynos and just can chose, but i have narrowed it down to the two. Looking to see what others have to say about what would be better and why i guess.

It helps if you post your setup. Normally NGK copper plugs work great and are used in many high hp applications.

 

but they make less HP and you get worse fuel mileage with copper then with iridium or other higher end after market plugs.

Haha. What ever you say man.

 

i have dyno graphs here that prove they make less horse power, so prove me wrong

 

the NGK iridium had one of the best overall numbers and definatly good bang for the buck considering that they last far longer then copper plugs. my only concern is that since the pulstar plugs work so differently that they may make even more HP if the timing had been adjusted.

On what setup?

 

your so useless, did you read anything on link at the top? those where dyno graphs using various plugs. in which all of the copper plugs where the lowest performers. why is someone who cant even read the only one here trying to give advice

Hahah. I am not trying to give advice. You are comparing a Neon...one car and the power/trq numbers that are +/-2 at most on one dyno that is not temperature or humidity controlled resulting in various K values that could account for the +/- 2hp. Seriously man. The only advice I give is from years of tuning cars and using various plugs. There is more to just peak power/trq numbers to selecting a spark plug.

 

I have always used NGK copper plugs, and they have never given me any problems. I like to check my plugs often to see how my engine is running, and I probably change plugs every other oil change or so. I don't like to toss plugs in and forget about them because they're "supposed" to last xxxxx miles, nor do I like to pay exorbitant prices for spark plugs when NGK R coppers are ~$2/ea at any parts store.

 

i have seen the dynos on honda motors as well, but those are the only ones i have available at the moment. but i have proof that copper is a waste. but all you want to do is argue. if you have a point to make then do it, show me some proof! all you do is flap your gums and blow hot air with nothing behind it.

 

Thanks for the input inspyral, just looking for the best bang for the buck and extra power from something as simple and cheap as a plug and with the price of gas what it is coupled with the long life of other plugs makes the total cost far cheaper then copper. I do agree with you on checking the plugs as often as possible to check for fouling and such to make sure my engine is running right. I check every oil change but have had good luck in the past with iridium lasting and running smoother. I ended up getting the NGK iridium to run for now. Just running bolt ons for now but building another motor on the side. I do think i will get the pulstar though when i finish up with the build, but im probably going to be getting all the parts together for the better part of another year so i guess thats a bit of a ways off. Thanks for the input though

 

Don't get Pulstar plugs. They're about as useful as the Tornado.
