so iread all this stuff on the forum about "thin wire iridium plugs" so where do I find them for my 07?

 

Autozone, advance auto parts, etc......

 

I have been doing a little digging and found threeiridium plugs that fit 07 Harleys.

Denso =IXU22, Bosch =YRD6LE, NGK =DCPR7EIX

Here's a link to a cross referance chart for Harley plugs.

Have fun looking.

PS I'm not absolutley sure the Bosch plug is made with iridium. The chart above says it's platinum, but its listed as iridiumon the Advanced Autoand Bosch's web sites.

 

Anyone have any info on if these plugs make a difference from the stockers?

 

If your willing to wait a couple of weeks I'm going to try and pick up a pair of the Bosch plugs tomorrow and install them to see how they work. I don't expect to suddenly get a bunch of extra HP from just a set of plugs soit will probably be a couple of weeks before I get enough "time" with them to know if they work better.
The reason I picked the Bosch plugs is that I like their 4 sided electrodedesign better than the more conventionalsingle ground electrode everyone but Splitfire uses. With four electrodes it 'shouldn't beas sensative to "clocking" as astandard plug can be.
