Iridium spark plugs?

[SpyderByter]

Shoot, I just picked up the most expensive one, it is made of 99% silver and comes in a small syringe. ($9.49)

I hope this is as good or better than what BRP has:

If not I will go and get the 276-1372A, and pull the plugs again:banghead:

Ceramic High density thermal compound...

In addition to the part number Scotty gave us Radio Shack also has the ceramic compound under part number 28-1098 for 6.29 for a 2.5 gram syringe. /Ken

The smoothness may not be imagination the GL1500 I changed from standard NGK plugs to the NGK gold electrode plugs went from rough to smooth. Also saw improvement in the MPGs. /Ken

How many miles on the standard plugs before you changed them to the gold plugs? Most times just replacing standard with new standard plugs
would make the bike run better.

Changed to gold plugs

I was having to change the plugs every 4 to 5 thousand miles on that wing. After changing to the gold electrode NGKs I could run 18 to 20 thousand miles with out the miss. With the standard plug they were missing by 3500 miles. We tried different heat ranges but no success. Only when I change to the 8 $ plugs did it perform correctly. Yep back then they were 8 bucks each. Now with gold so high... they're probably 15 to 20 each. /Ken

I understand now. I might try iridium's, I have to put in new exhaust gaskets any day now might as well kill two birds with one stone,.
Thanks :thumbup:

 

[krb1945]

I also am going to...

try the IX plugs. I just ordered 6 today. The price on amazon is pretty good. I am currently changing oil and filters preparing them to roll. //Ken

Just put mine in today and went for about an 80 mile ride. I can't say I notice any more horsepower, but the engine seems smoother somehow. Maybe just in my head, but it really does seem smoother.

Just ordered some for $6.99 each:

Have to order box of 4.

Iridium Plugs

Put the Iridium plugs in a few days ago, Got them at Autozone 14 dollars for two. The original were burning perfect [1100 miles] So far i only have about 175 miles on them, I don't notice any difference yet. I did put new Y gaskets in at the same time so the engine is running a lot quieter. After a few more tanks of gas I'll check my mileage to see if they make any improvement opcorn:

what gap do you set the plugs to?

 

[boborgera]

what gap do you set the plugs to?

0.76 mm .030 sae Just me but i have about 200 miles on them now, this Saturday I'll be going on a 180 mile trip, If there still running the way there running now they will be coming out and new stock ones going in.
It seems like i lost a little snap when i open it up. Slight hesitation on full throttle. Will know more in a few days.

 

[krb1945]

Plug gap is...

correct. Tech manual states .027 to .031. Hope you put the heat sync paste on the threads. If you didn't they can't get rid of heat and will break down. The white ceramic paste is available at radio shack. /Ken

:2thumbs:
Yep, Used the heat sink paste.

Good Read

Not just the install, but other tech related stuff.:thumbup:

I'm going to give these Iridium plugs a try. I've got 16k + on my Spyder with the original stock plugs and they are starting to miss. Would have been a good excuse if I'd tried my hand at the "Perfomance Testing" at Cowtown and lost!

But since I need to replace the plugs anyway I think the Iridium are a good choice. I may not see any improvement over new stock plugs but over time the Iridium will maintain their performance while the stock plugs will normally lose function.

At $8 ea. delivered it's not a big hit.

Radio Shack has several types of heat sink compound. The cheapest is a small (6.5g) tube of silicone based compound (like the BRP P12 compound) for $3, P/N 276-1372A. The BRP compound comes in a larger tube for $40. I expect there may be intermediate sized tubes available somewhere (electronics stores?), but Radio Shack is the most readily available in many localities. Radio Shack tube is enough for several spark plugs.

Scotty,

Is the BRP compound silicone based as well? Based on reading the shop manual, silicone products can damage the O2 sensor downstream.

Anybody have any ideas?

Arctic 5 is some of the best thermal past you can get. What you're looking for is thermal transfer and this does a very good job. Silver is more expensive than ceramic and also works a little better. It is used as a benchmark against which other products are gauged.

Arctic makes this same product with ceremic (aluminum oxide, boron nitride and zinc oxide) instead of silver called Silver Ceramique (I think the silver here has more to do with the color - and maybe a little marketing - than content).

These componds are not silicone base though. Instead, it uses a multi-compound, synthetic petrolium base that does not vaporize. It is supposed to be better and more stable than silicone.

I'd say you just went overkill on this but it will work just fine. You'll get a 5%-10% better thermal transfer than with a silicone based ceramic product which probably will make little to no real world difference but you can feel really good about it! :thumbup:

Just installed these today, havent got to run it yet though. Are any of you guys finding any dirty or debris on the underside of the plugs ( where the washer is)... i pulled out my front plug under the airbox and i noticed the underside of the washer had dirt on it... and on the head where the plug sits there are small traces of dirt.... should i remove these before reinstall the plug?

If you already put in the new plugs with out removing the dirt forgetaboutit, If you still have them out, I would try using a vacuum cleaner with a small hose attachment and try to suck out any dirt you can. You don't want to push any dirt into the cylinders.

I pulled the plug back out before i saw your post about the vaccum... the dirt was stuck in the thermal compound torward the bottom on the hole where the threads were i tried it wipe it out with a qtip which seemed to work alot of it came out... pretty sure nothing fell in, did the best i could. i did notice some dirt on the last thread by the plug tip so i was sure to wipe it off... it was very small deposits.
