Toyota Corolla Spark Plugs

[Trav]

They have a metal shell plating that should make them easy to remove no matter how long they've been in there

100% not true no matter what NGK claims. I have run into stuck plugs with the "plating" many times. Check out post #9

Thread '2009 honda civic GX won't start, cranks, sometimes fires a bit'

Dec 20, 2024

Hey all, about a year or so ago I had a crankshaft position sensor go out so I had it replaced, but they did it with a non-OEM part. a couple months later it wouldn't start again all of the sudden. I assumed it was because they used a cheap sensor instead of OEM and it went bad again, so I provided the OEM Honda part and had them replace it but before they could the car magically started working and starting again. Nonetheless, I had them change it out to the OEM part anyway

Fast forward to now, and it won't start again. I took it to a different mechanic this time and told them my story...

Just a wisp of anti-seize for the win! Too bad what NGK says. My guess is they are trying to avoid the "too much is just enough" guys.

The legal ramifications are far too great for them to recommend it, some hammer head goes and lathers up the plug and causes a cat destroying misfire NGK would have to deal with the EPA for authorizing the use of cat destroying products. That and over torquing causing stripped out threads would hook them with the car manufacturers. NGK (and any other company that recommend using it) would get sued out of existence.

You need to write some papers on proper maintenance. You already taught me how to use a torque wrench properly. And I thought I knew...

Too many Bozos out there who don't know the basics and need to learn.

I went to trade school starting in 1971 and the cars that were brought in were about 10+ years old. Since I left in 1975 everything has changed, when I first started a lot cars still used draft tubes before PCV valves, absolute relics by modern standards. Experience along with continued schooling is the only way to keep up to date.
One book that is the foundation of most 4 year trade schools is this one. If one is dedicated enough to read and understand it will more than help gaining the knowledge needed. No need for the latest version unless you intend working on the latest vehicles the 4th edition and up can be found much cheaper.

I thought the mention of 14 mm (9/16") plugs was a mistake, but based on subsequent posts it looks like that's a new standard size.

Most spark plugs when I started wrenching were 13/16", gradually phased out in favour of the smaller 5/8" size.

My two spark plug sockets are 5/8" and 13/16".
