Iridium- no discussion. Buy them!

[VentureFar]

I just replaced my standard plugs with iridium.

They had 22,000 miles on them.

bike was hard starting.

First start with the iridium was “click varoom”

I don’t know how my mileage will change but it sure started faster than it ever did, ever!

very impressive.

I agree, as I had a similar response when I put them in my '06 when I had it and I'll be putting them in my '18 SVTC on the next change. They were originally recommended to me by a riding buddy. They will also far outlast the 'standard' plug that comes with the bikes and will likely go 60,000 miles all the way to 100,000 miles.

Yep I swear by them, put them in every bike I own. Quicker, easier starts, long life and no fouling problems. They are worth it to me.

Plugs have been discussed many times. This thread from 2012 was good - https://www.venturerider.org/forum/showthread.php?44449-Which-spark-plugs-to-use&highlight=iridium

One comment in that thread was "rumour" that the iridium tips could break off.
