Spark Plugs at 65K
 

This is what my Plugs looked like at 65k. I'm no expert but I wouldn't recommend running them until 100k like most Subaru engines specify.

Can't tell much from that angle.

Doesn't the manual call for replacement at 50k?

The manual for my 2013 FR-S calls for spark plugs replacement at 60,000 miles.

I think they look pretty darn good for 65,000 mile plugs ..... ;)

Here ya go .......old man ........ :D

Damn. Are you burning oil at all or using anything but 93? I'm at 91k, been using E85 for a while, not sure if it helps keep them clean or the extra fuel needed makes em dirty.

:thumbup: I remember a whole bunch of people saying it was suggested during their 50k service.

I didn't actually want to look it up in my manual.:lol:

It might burn 1/2 a quart every 5k. I use ethanol free gas to keep the crickets at bay... The highest octane I can find in my area is 92. Bought mine used with 59k, I have no idea what previous owner did.

Bleh. I plan to change mine at 100k anyway unless something comes up. Mine has been through 93 for half its life, corn for the other half. This is something i've always wondered about, so close to seeing the condition of the plugs. Was your changed at a dealership or at home? I want to do it at home, but as far as i know, nothing has made it an easier than lifting the engine.

Unless your electrodes and/or insulator are seriously burned away, or the plug is fouled with goop, I woudn't sweat anything. Honestly, in my 40 years of reading and changing plugs in all manner of engine, including aircraft, it seems like most people tend to make too much out of it. Just a middle-aged fart's HO.

On the flip side, you already took the time to remove them, fuck it. Plugs are cheap.

...except aircraft. Whole different ballgame. Those see a sandblaster as needed.

ah yes, The SANDBLASTER! Soooo many reconditioned plugs!
changed out SOOOO many of these when working as an A&P in the 80's n 90's

If I could only get one to shoehorn into my BRZ! I just know I could make it work somehow.
Note the 6000 stands for +-60,000 HP
Wonder what WHP I would get...

Maybe if like a famous song I carried out a part a day in my lunchbox?

I NEED A BIGGER LUNCHBOX! WITH WHEELS ON IT!
