What car are you putting these in? NGK plugs rock. I run NGK racing 7's. Very hard to find them because they are not the regular NGK plugs.

Buy plugs that came with the car. You will have very little to NO diff. with plugs.

GM = AC Delco
Ford = Motorcraft or Autolite
Europen car = Bosch
etc...

No reason to use them in the work truck and what mods do you have on the CRX?

You are VERY wrong. NGK plugs for my setup gained me lots of power. The plugs are also great for my nitrous setup. The cars runs so much better with colder plugs in my case.

That makes sense since they have alot of choices for temperatures to choose from. There are alot of them on ebay for about 30 to 40 bucks, I found them for 28 myself.

I do believe it's the NGK 6s that I'm used to seeing in nitrous setups.

The etc was for people that had a brain and could build on Jap cars = NGK or DEnso, etc.....

And if you have mods then a different temp plug can help.

I am a realist here not expecting big horsepower gains since horsepower is more to do with getting the air fuel mixture in and out of the combustion chamber as fast as possible. But it doesnt hurt to burn the mixture better either, this can gain SOME hp.

Isn't a spark a spark? How will a spark from a iridium spark plug ignite the fuel air mixture any better than a spark from a copper plug?

Yes lots of people use the TR-6's. He does not need those for his setup. I actually don't use the Racing 7's(different from the TR series). I use the 8's which are three steps colder than stock. Part number is R5724-8.

Anyways with the mods you have done I wouldn't see why you would waste the money on Iridium plugs. The stock NGK plugs for your car will work fine. Make sure you gap them correctly.

Well yes and no the copper plugs work well also but these perform about the same as copper but last MUCH longer. I have read about copper plugs also and everything I have read says they can burn out faster according to the so called experts. So I look at it this way same performance but longer life why not give them a shot, but wanted to see if anyone else has used them.

I really doubt you will gain anything significant with the plugs unless your old plugs are fouled or really old.

I don't have a Japanese car. The NGK plugs are awesome for lots of domestics.

Like I said... you will be wasting your money because those plugs are not cheap. What kind of mileage do you have on your plugs right now?

I would be happy with smoother idiling and better start ups. I dont have my hopes set too high and dont buy things based on hype, but if these suck then maybe I did this time. lol

Plugs will not fix that umless they are fouled out.

Need to check cap, rotor, plugs, plug wireset, and fuel filter. Also clean out Throttle body and F/I's. Don't waste your mopney on some snake oil

As Marlin and I have pointed out you will not gain anything unless your plugs are fouled. You will be wasting your money. I say follow his advice and check the other things if your plugs are in good shape. What mileage are on the plugs? Have you pulled them and looked at them?

Nah havent checked them in a while so just thought I would get them as for the other things they are fine the NGK wire set is still ok as are the cap and rotor. The plugs do have some miles on them since it burns some oil its time for new ones.

1st point: No scientific study backs this assumption.
2nd point: It depends on the heat range of the spark plug.

Marlin, have you ever checked out the Halo spark plugs? They look like they actually work. Then again, I haven't found any independent lab tests.
