NGK V power are the correct part number for the Accord.

[GeoffM]

NGK V power. About 2.29 when I left work. IIRC, there are actually some better NGKs for the same price, or cheaper. You'll just have to look around.

[90cb7matt]

ok its getting about that time to change them i mite try the v power

You don't need any plug fancier than what the engine requires. No irridium, no platinum... regular single-tip copper plugs are fine. NGK and Denso seem to make the best products for our cars. I've used fancy Bosch Platinum +4 plugs in the past, and they were terrible.

yea i know alot of people with high dollar plugs that made their car run poorly, the ngk iridiums i had really didnt make a difference but more important it didnt make it run worse

[Fleetw00d]

I had a set of NGK platinum's in my EX, but was having problems with rough running under acceleration (about 20K on plugs, but it had been doing it for a while). Standard set of NGK copper plugs improved it quite a bit.

[GeoffM]

The only difference the mroe expensive plugs will make is change intervals. Our plugs take less time to change then it does to actually buy them, so it doesn't matter. The only reason I'd rock the better ones is if they were the same price or less than a dollar more.

Very true. My Fit runs platinum plugs from the factory... and I'm thankful for it. They're a bitch and a half to change, so I didn't have them changed until nearly 200,000 miles! (that is WAY too long for a plug change...)

Did they let you see the plugs? I'd like to have peeked.

I'd like to take this time to recommend anti seize. I pulled 2 of my spark plugs and it took all my might. The whole time I was afraid of stripping my head. I have 2 more to go. I didn't actually have any anti seize handy, so I used dielectric grease I had on hand. I plan on pulling all 4 and coating them with anti seize.

No one wants to re-thread a head!

[deevergote]

I have 2 damaged plug holes in my H22... one of them is bad enough that the plug gets pushed up in time, causing a terrible knock until I tighten it back down. It is VERY easy to damage the threads in our aluminum heads! I always thread them with an extension, no ratchet, until they're finger-tight. Then I put the ratchet on, grip it around the head, and apply just enough pressure to ensure the plug is snug. Anti-seize is good, but not terribly necessary, as long as you change the plugs regularly, and your engine is in good condition.

And no, I didn't see my 200k mile plugs... I should have asked! They did save a piece of my busted clutch, though. Its on my desk right now.

[GeoffM]

I've found out that once something threaded into aluminum gets hot, you can actually tighten it down more. I've done this with the spark plugs and the top shift solenoid.

I am now terrified to remove either.

Editz: It's been 15-20k miles on mine. Idk if that's time (not quite a year) or what I mentioned above. But they are very difficult to remove from a cold head.

Amen on anti-sieze and proper torque. I tried towing my wagon to FL with my E350 taking my daughters back to school over Labor Day last year. 37 miles short of Louisville my Triton V8 puked a plug. Unfortunately, I was the one who had installed them (about 50K before); they can be a bear to get to in this van. $900 later I had a insert and a whole new set of plugs. If I blow another one out, it's Ford's fault.

I always do it cold. Hot aluminum is more malleable, I'm quite sure.

What sort of insert was used? Time-sert or Helicoil? Helicoil isn't good for fixing sparkplug threads... I learned that as I researched what it would take to fix my car. Of course, for what it would take to fix it, I can get a replacement head for less (and I did!)
