Just changed my spark plugs! pics of old vs new
 

Did it without raising the engine. Was a PITA.

Busted knuckles guaranteed. I'm right at 60k miles and the plugs don't look great to me notice the white part of the spark plug. It has some corrosion starting to creep up from the head. I'm not sure if that is normal but perhaps one you you guys can chime in

I've seen that and I would not be concerned about it. Mostly surprised that there was no never seize on the threads.

I never thought this was that hard of a job. I used a flex adaptor and a magnet to fish everything out, never had to raise anything either.

My flex adapter broke while trying :bonk:
The hard part was seperating the extensiin from the socket. Since mine have those little detents
Used An extension a hose and a magnet. Ive read or heard somewhere your not supposed to lube these plugs

Looks like you could have gone another 30k miles.

Damn that would make it harder. I just pulled the flex out far enough I could see it connect to the short extension I was using, then shoved a flat blade in there and twisted them apart.

I never heard not to lube them. I don't put plugs in without never seize. I have fixed enough stripped threads I don't care to have to deal with it again if I can avoid it.

Easily. Looks practically new.

Those look almost pristine. Back in the carburetor days before ECU fuel/air management the plugs were good if they lasted 5,000 miles. To get 60,000 out of them and have them still look that good is a technological marvel and a true statement of how far things have come.

I was disappointed when mine were changed at 138,000 miles the mechanic didn't save them for me as requested of him. Really wanted to see what they looked like after twice the expected lifespan.

I will see what mine look like when I finally get them changed. Probably be three times the recommended mileage by then.

Yep, back in the day, I would have put those puppies right back in.

Today, if it weren't such a PIA to get them out, I would put them back in - but, since they are out - I'd replace em.

I would have run them through a blaster first though.

Anti-seize has always been standard on plugs going into aluminium heads for me.

Yep, fer sure. I recall back in the day to tend to spark plugs meant to stop in at my Uncles Chevrolet dealership, pull the plugs out, put them on the sand blaster machine, gap em and put them back in. The whole process was a 15 minute job.

Picture of a back-in-the-day dirty plug, for the young-ens that think their plugs, with a slightly discolored insulator, are "dirty". - :)

Plug condition was vital for diagnosing issues. The ECU has done away with many of those problems though.

I got to know the local county sheriff as a teenager doing plug chops on empty back roads when tuning on two stroke bikes. How else did they expect me to do it?

Those old plugs look good.
I grew up checking spark plugs in snowmobiles but with 4-strokes and modern injected 2-strokes, those days are gone. Nothing like getting a jolt off the plug while checking for fire. Lucky, I stihl have my modded chainsaw. Even then a pulse tach is needed.
Here's some Kevin Cameron of Cycleworld Magazine.

Yep, hot, bright, sunny summer day, the gasoline engine on the grain elevator wouldn't start. My father checked the gas, felt like it had compression, come here son, hold this while I pull this rope - :eyebulge:

I wonder what todays CPS would have to say about THAT!

Same story just replace "grain elevator" with '1954 Ford dump truck engine' and "pull the rope" with 'connect these wires'.

Or replace it all with electric hog fence, and "hold my glasses while I grab this wire"

I broke one on my old ae86. Took me like 2 weeks to realize I should get help in taking it out. Mechanic came over and in like 40sec took it out. Learned a lesson. “Don’t wait too long when changing them and use anti seize.” It’s well worth it. I’m not even going to try for this car. Don’t wanna mess it up with how uncomfortable it’ll be in doing this.

I hope my plugs look the same. I’m doing brakes this paycheck. Running 18 TRDs puts more wear on my brakes. Next paycheck plugs. Gonna stick with oem Denso.

What side is easier to change? Drivers or passengers?

No.

both suck equal. had to remove the DI computer on the passenger side.
had to remove the injector cover for the driver side.
removed the strut braces for both.

Also I read that putting a conductive grease on these can mess with the grounding.

Was hoping one side had more room than the other so I could chalk up a win and build my confidence to tackle the other side. But I guess not.

Approaching 100k miles and already bought the spark plugs and belt.

those look like my 2000 accord's spark plugs that i first changed at just about 200k lol. God i miss that car, so stupidly reliable!

The corrosion you see is simply due to slight moisture and the effect of dissimilar metals, the aluminum in the head interacting in a galvanic process with whatever the spark plug is made out of as well. Also the heating and cooling cycles they go through make this plug normal and would've definitely effected it's ability to be removed had you waited 30-40k more





You really should listen to what others posted like @NoHaveMSG, @Tcoat or others. NGK only says not to use anti-seize because they believe clueless mechanics will over torque things, which is technically true. You're torque wrench becomes offset by 20% with the use of antiseize or a lubricant, but you can easily just correct for this with simple math.

The grounding is a non-issue, that's done through the coil packs not through the threads. Get yourself some vibratite 9072 or loctite 76764 and apply a conservative amount to the threads....

Those don’t look bad at all. I’m over 100k miles on mine and got a good deal to do mine so I went ahead and did it.

Had the guy save the old plugs. The head of mine looks like your but didn’t have the dark color on the white. Think I could have gone another 50k on mine.

I think I need to take a shower after seeing that picture... Thankfully only 7k miles so far. Another 53k to go!

That's cool. I had never seen the brownish buildup on plugs until my last set on the FRS. Kinda worried me but not enough to go diagnosing. Glad to know it's normal lol
