Here's a ? for all of yous...how many of you index the plug when you put them in???? jmcollision

How is PA? I use to all the time on Evo 14 mm plugs but couldn't find index 12 mm washers til now, fr. http://youroilshop.com/plugs.htm thanks to 1931jamesw on a prior thread. Makes sense to me. How many know what it means? You are positioning the gap towards the intake which allows better combustion. I also replaced plug wires w Taylor Thundervolt 8.2mm wires. They use to have a hotter SE coil for the EVO but with the new ECM etc. I don't know if you can change, anyone changed their coil to a hotter one?

 

2010 Street Glide:
- Denso Iridium Fine-Wire Spark Plugs (IXU22 gapped @ 0.040")
- Screaming Eagle 10mm Spark Plug Wires

 

I used to years ago, in my Buells with HP engines.........then there was controversy as to which direction to point them and whether it did any good or not.

Now I just make sure I get them in the hole.

 

I use NGK's. Never had a problem with them.

 

I slap a set of NGKs in the EVO Road King every 5k. No problems.

 

Good to hear from you GMC...PA is good thanks....lots of good riding in the sunshine with cool crisp air running over this bald head (THANK YOU no helmet laws!).

 

Mine are white with a silver top.











Sorry, couldn't help but be a smartazz.

 

Dawg, what do you gap yours at?

 

I've run all the brands and styles mentioned and have seen no difference. $1.50 for Autolites works for me.

 

Come on!!! there's got to be a better plug out there.

Who indexes their plugs? Does it run any better?
