Is there really a difference in a $18 spark plug???

[24gt]

Got three NGK IRIDIUM IX plugs. And found out they were $18 dollars apeice. I thought they were only 8 or 9 dollars. My question is will my stock 2005 S3 really bennifet from them, or are they more for race type engines? I have a K&N air filter and tors with tor map in the bike.

Only if you use the right oil. :-D

And break them in hard. Plugs that are broken in gently will burn that "right oil."

HA , HA , HA , HA , HA. - $18 plugs are worth it if you think they are. I use the $11.00 plugs.

I went from standard NGKs to the NGK IRIDIUM plugs and found no appreciable difference between the two.

There is only one advantage to using and Irridium spark plug. They do not wear out like a standard plug. The disadvantage is that occasionally the spark plug itself will break before it is ever even close to wearing out. They last so long the porcelin will crack or so might the center electrode shaft. They say irridium plugs will last over 120000 miles in a car motor, but having a spark plug in our motor untouched for 6 years creates its own problems. I use the irridium plugs, but still replace them after about a year or 2.
Irridium plugs do not enhance engine performance at all, EVER.

Yeah, there's a difference - about eight to ten bucks.

Got my Iridiums at $10 each and felt absolutely NO DIFFERENCE what so ever.

For Capt Rat/rckrzy1/anyone else: Why did you install iridiums? Were you expecting a measurable performance increase?

Yeah, well, when I bought my Speedy, they threw in the spark plugs for FREE. :smug:
