75 a pop damn...not for me:no

Well, what would you use...?! throw a dog a bone, for fecks sake :)

if i had a bone id throw it for ya:lol:thumbup

Have you tried the NGK Iridium plugs? They're good and reliable, not too expensive, and I don't believe those $75 plugs are that much better than these... If you don't like NGK, Denso also makes them...

Notable properties of Iridium are its melting point - approximately 2450 degrees C, considerably higher than Platinum, and it's strength - approximately 8 times that of platinum. The table below compares the characteristics of Iridium with those of other precious/semi-precious metals commonly used in the construction of spark plugs.

What about those new 'pulse' plugs? Seen or heard anything about those?

Pulse plugs? You pulling my leg? havent heard anything about em........

with stock coils nothing will work better then stock plugs or iridium ones.
iridium will last longer.

Actually, I just checked their site, they don't make it for the R1... :lol

The 75$ plugs I mentioned are special YEC recommended plugs for the R7.
I'm going NGK prolly.
Just wanted some input

No doubt they're probably really good plugs, but I think the plugs worth $20, and the $55 go to the 3 letters "YEC"... :crash

By the way, the YEC plugs are produced by NGK also, I'm sure you're aware of that... :)

Yes I noticed they're different than the conventional plugs, I've seen similar plugs for cars by Bosch I think or some other brands, forgot the exact brand. They claimed that it's suppose to create a better output to the conventional design. But I'm not sure if it's worth $75 a pop though... :dunno The ones I saw for cars were like $25-$30 a pop iirc.
