I have over 12k on mine
Pull them when I change oil.

Deep plugs very light grey
Shallow plugs light tan

I used 4419's for about 1k.

There is a lengthy thread about 4419's 2 or 3 weeks ago

I just started using NGK BKR5EIX-11. It's an Iridium electrode plug. About $7.00 each. I'll have to run them for a while but reliable sources have good things to say about them (no grand claims. just a good plug)

I use them and love'em. Got about 2500 on them. I spent way to much for them though. Here they are $14.00 bucks a pop. I was told they are allot cheaper on Sparkplugs.com but seems like you got a good price for them.

I didn't count shipping in the price. Blood, guts, and feathers it's around $11/each there.

You mentioned a different part number than what comes up if you put the model and engine of the 1800 in.(IFR5L-11)
Will these plugs be the same as the ones they give you? and do you have to re-set the gap?

I checked the gap on them and it was fine. I got the part number from a friend of mine that is running them. The IFR5L-11 is indeed the correct plug. I don't know what the difference is. Probably heat range.

The IFR5L is the stock plug. It's an iridium/platinum plug. The BKR5 is iridium/steel and has a higher resistance. It works, but whether or not there's a performance difference, I don't think anyone has tested it one way or the other.

The stock plugs are only slightly higher in price on sparkplugs.com or HDL. For what little cost difference there is, go stock. Better safe than sorry.

We went to O'Reilly's for plugs for VTeXan's bike and they cross-referenced a plug; I believe it was the BCP5EP-11 referenced in the first post. He told me they didn't work, but I never asked for specifics (here's your cue, Brian). We were looking for the BKR5EIX-11's to try them out, but naturally none of the local stores had any. But then most of our local parts outlets have names like "Dink's Live Bait & Used Tires".........

I asked NGK via email about these two plugs for my 03 1800 retro. Here is what they said when I emailed them with the question of what is the difference between the 1FRL5-11 and the BKR5EIX-11. Below is the reply:

" Hello,

The IFR5L-11 stock number 6502 is the original equipment spark plug for
this application. This spark plug has an iridium center electrode tip
and a nickel alloy ground electrode with a platinum disc welded to the
backside. Due to the fact this motorcycle has a direct ignition system
the spark plugs wear rapidly. This spark plug will provide the best
performance and durability.

The BKR5EIX-11 is a single iridium spark plug with a nickel alloy
ground electrode with no platinum disc on the backside. This spark plug
will ignite very well, however won't last very long in the application.
