NGK Iridium Spark Plugs

[Unnamed]

Yoo smart guy , check the below link , i think still not late for u to learn new things in your life...........

Copy from NGK web site as......


Occasionally drive under high-speed conditions (approximately 80 km/h or more) to ensure spark plugs reach their self cleaning temperature.


I m racing over 2 year and this is very funny that you try to teach me what is spark plug ,

so now think who bullshit  ......

I don't think its bullshit that plugs get fouled. I think you just totally made up your numbers. You sure as hell don't need to hit 8k rpm to get to 80kph, and I still don't see anything saying to do it on a weekly basis. The only time I've seen people needing to clean fouled plugs are in the MSF course when idiots leave their choke on and ride at 3k or less for an hour.

I run Denso plugs, I noticed better accelleration easier start and smoother idle.

could just be old plugs in the first place. but I'm happy with the results.

I used to own a custom shop "Crucial Custom" cars mostly, when people came to me for more power I would first recomend Denso plugs, Nology wire's, intake and exhaust. The results are great, so I'm going to try the some on my bike. I not sure if Nology make wires for our bikes but I've seen them on others.

has anybody tried better coils or know of something better to get a hotter spark ...boost the power

I'd say that your Pretty muc stuck with stock unless MSD Coils ETC. are Hotter. IMHO Stock is Hot Enough.If it's Sparking Correctly then it's running Correctly.

[Crucialval]

I've been unable to find an exact ohm match with aftermarket coils. But I'm sure Nology wires would give the plugs every thing the coils have to offer. In my opinion you probably couldn't use any more spark efficently without getting more air/fuel in and out faster.

i have these in my truck.

the stock copper plugs had a faint glow in the tester (120psi)
the iridium plugs look like a mig welder arcing (120psi)


dyno pull showed a 7hp increase and 14tq increase. idle was smoother, less hesataion, and easer starting for the high compression

[CirclesCenter]

I know in a V8 (Especially a hemispherical combustion chamber) the angle the plugs end up in the chamber at can give you a 1% - 2% gain in hp.

So a 0.5hp increase on your GS? (  )

That NGK site has the following info on Iridium plugs. Think it's worth dumping it here for reference sake:

Iridium Plugs bring these benefits!

·    Improved acceleration
When you switch to Iridium Plugs acceleration is improved. There is a fast response to throttle operation and you can feel the difference compared to plugs in original plug.       

·    More engine power!
Iridium Plugs improve the engine performance in terms of power. The extra power becomes apparent in situations like climbing hills, giving you a comfortable driving and touring experience.       

·    Improved ignition and starting characteristics
The ultra-fine center electrode of an Iridium Plug ensures fast ignition and improves the engine's starting characteristics. Since there is little dispersion in the position of the spark, idling is stable too.       

·    Better fuel economy!
Since Iridium Plugs ensure excellent ignition, the gasoline is burned efficiently. These plugs provide both economic and environmental benefits.

Iridium Plugs are different in these respects!

·    Use of iridium alloy makes a difference in performance!
The iridium that we use is a new alloy. In comparison with materials like platinum that are used in general-use plugs, it is a superb electrode material with an excellent melting point, hardness and strength.       

·    Improved ignition due to fine electrode!
Since the electrode is fine, which means that it is conducive to spark formation, the spark energy is large and ignition is improved. This produce the ultimate performance of the engine.

Iridium VS Normal


      
·    Resistant to fouling, so maintains high performance!
The "thermo edge" burns off deposited carbon (product of combustion), preventing deterioration in the ignition performance of the plug and maintaining high performance.

Breakage of the Center Electrode Tip

Spark plugs with fine electrodes made of iridium or platinum have "Do not adjust the spark gap" written on their packing boxes.

1)    This is to prevent the general user adjusting the spark gap and breaking or removing part of the fine center electrode tip as the spacing tool makes contact with it.

2)    When the tip of the center electrode is broken, a nick is sometimes left on the ground electrode too.

Checked my plugs today. After 20,000km's they still look superb!!!




As for non resistor plugs, they badly effect digital tv reception

but your not watching t.v while riding .......are you? lol

[galahs]

Hey, if cagers can mindlessly watch their sat navs whilst driving their SUV to pick the kids up from soccer, I thought I may as well put my life back into my own hands.

[Teek]

I just installed NGK Iridum plugs and I had smoother idle and less hesitation as well, but also had some unusual loud popping in my exhaust on and off. (I think it was me, there was a racer boy 350Z pacing me for awhile, it could have been him. I also added Seafoam to the gas for the first time, so I don't know if it was the combination... I did notice that my "sticky idle" seemed like it was not staying stuck so long at higher rpms than it should when coming to a stop, especially at a light, it was about half as sticky by the middle to the end of the ride. Thinking that was the Seafoam. Of course the new 14t sprocket probably helped with the feeling of hesitation as well. haven't pulled a plug for a look see yet, but they seem fine. Cheap on feebay too.

[galahs]

My bike runs a touch rough when it has carby cleaner in the tank. Hard to describe but it feel hesitant.


My bike pops and crackles on rapid de acceleration but that was caused by the K&N Lunchbox airfilter and straight through exhaust. By suddenly snapping shut the fuel supply the bike is running lean for the revs its carrying.

[Teek]

With your set up that would not seem to be uncommon..?  The pops got really loud when the z was right beside me, but I couldn't tell through my helmet if it was ma and the noise was reflected off of him so I could hear it better, or if it was him. My riding buddy also said the z was noisy... but I heard pops for awhile on and off. Will see if it's back tomorrow.
Thanks for the input!

[TREXSTER]

I'm gonna get a Denso plug, with a 1989 bike with 38,000 kms it will probaly be the last plug I get for that bike. EBAY has them for $20.00 delivered can't go wrong,(I hope).

[Teek]

Yeah, I think I popped for $18. delivered on the Iridium. Post back on the Densos please?

Comon on bikes or cars with free flowing intakes and exhausts.

[TREXSTER]

Will do Teek, probably be another month before the roads are fit to drive on for a bike around here,I only get about half the year of driving time..

[Teek]

TREXSTER, I'm so sorry! A bike and rider stuck inside is no fun for either one of them.

galahs, my bike has none of that free flowing anything except cash out of my pocket which is now empty for awhile.   

Popped while warming up on choke on the second test run, 1st ride was 75 miles PCH and canyons, last Sunday was only 35 of same, but she's running smoooooth, and the throttle response is very good. Less lag and a quicker return to idle, so the Seafoam is helping.
