2012 Accord K24 spark plugs.

[aquariuscsm]

I’m at 117,000 and spark plug replacement has been on my mind. What’s the best choice in plugs? They’re for my 2012 Accord EX-L with the K24 engine. Someone on Driveaccorf.com mentioned Denso. I’ve only ever bought NGK for pretty much everything. What about Honda oem (whatever those would be) from the dealership?

Thanks in advance!

Our 2006 TSX with the mighty K24 came with 2 Densos and 2 NGKs from the factory. Imagine that.
Either plug will be fine.

Honda will sell you the same plug. And you will likely pay a nice premium to boot!

So you're too keen on maintenance are ya? How can you sleep at night?

I think I've heard of Toyota having done the same thing. Interesting.

In my 2009 Accord, I ran both NGK Laser Iridium and the Denso Iridium and noticed no differences whatsoever. I'd buy based upon price or availability. FWIW, Denso were the OE plug in my 2009.

NGK Laser Iridium, but there is nothing wrong at all with the Denso version.

If I recall right Toyota runs both Denso and NGK plugs from the factory on their V6s and V8s they'll run 1 type in one bank and the other type on the other.

I wonder what’s up with mixing the two different brands from the factory??

OE NGK, dealer plugs come pregapped. Denso seem to fail much quicker.

Japanese companies kissing up to each other and not playing favorites.

Factory plugs and call it a day.

I use either. I actually like the Denso TT or the NGK Irdium IX as replacements. Have run both to several times 100K no issues.

 

[BAJA_05]

NGK Laser Iridium also!!!!!

 

[UG_Passat]

Those twin tip plugs are the rage right now... so you can get the equivalent Denso TT's or NGK Ruthenium HX

You can take one plug out and see what the oem was and replace with same. I like NGK.

i put ngk laser iridiums on both my gmc's last year in october. i wasn't expecting a big difference but my rwd sierra actually burned rubber again and i averaged 1.2mpg more and my awd denali pulled a lot harder for sure and got 0.8mpg more.

if you're gonna own it for another 100k or more put laser iridiums on it or those new rutheniums if you're feeling fancy. if you're gonna have it for another 100k or less just cheaper platinums should do you just fine. My sierra really suffered it, had about 150k on its original plugs and my denali had about 120k since i did them before.

i wouldnt go crazy over the oem ones like some do. aftermarket is fine. check oreillys website they're good for finding and cross referencing plugs.

To my knowledge the OEM Iridium plugs on most GM stuff are NGK Laser iridiums, if you buy a set of Delco plugs they have the laser iridium part number stamped in the plug. Delco plugs tend to be the best value when they've got the rebate going they're often times cheaper than buy NGK branded plugs plus you get the $3/plug back.

yeah i know that a lot of oem's outsource to ngk and some others but last time i checked the oems were a bit more compared to regular platinum ngk branded ones. i didnt know about the rebate so thats a factor.

The PZEV models use a different plug. Check the underhood label.

Ruthenium.......last set of plugs you will ever need.
They are great.
Used them in 3 different cars so far, will try #4 this spring......maybe winter.
