CAR: 2015 Accord Sport 4cyl/4door with 116,000KM

No issue with how the car runs so this is preventative maintenance. Which spark plugs are best for this car, how often should they be replaced, do they need to be gapped?

Manual asks to wait for maintenance reminder but i am not sure if it has been reset by previous mechanic when doing oil changes.

Sorry for noob question, could not find this info on the site. Thanks.

Better or "Best" spark plugs?

Bosch Double Iridium Spark Plugs 96310 NGK Laser Iridium Spark Plug 96964 DILKAR7H11GS Denso Iridium Long Life Spark Plug 3492 DXE22HQR-D11S From 'Googling', I see these 3 spark plugs recommended most for my 2015 Accord SE I4-MT. I have an intermittent misfire again on cylinder #4 (P0304) but...

Which spark plugs are best?

So I'm changing the plugs in a 2014 accord ex-L 2.4 non PZEV engine (car was bought new in TN so I assume its non PZEV?) In my research I've found four different plugs for it: NGK: ILZKR7B-11S Denso: SXU22HCR11S Denso: DXE22HQR-D11S PZEV NGK: DILZKR7A11GS I bought the Denso SXU22HCR11S but...

Spark Plug Maintenance Interval?

My 2017 Accord EX-L has 107K miles. I decided to go ahead and buy new NGK laser iridium spark plugs and will install them myself. I never received a maintenance minder indicating spark plug replacement. Is it unusual to go over 100K miles without the need to replace them? On a side note, I'm...

NGK or Denso are the OEM plugs. Stick with these and you'll have no problems. NGK #DILKAR7H11GS or Denso #DXE22HQRD11S . Prescribed replacement is at 100,000 miles. And gap adjustment is not recommended as it is very easy to destroy the plug tips. I personally do check and adjust the gap , but I've done hundreds of precious metal spark plugs. Gap is 0.044 inch.

Unless you dropped them, no need to gap them...they'll be pre-gapped from the factory.
Iridium plugs can go 100K miles or further.

I spoke to the dealer and they quoted $124.36 ($31.09/EA Canadian before taxes) for all four plugs which is very comparable to what I find aftermarket. They stock NGK 12290-5A2-A02 (their part number)

Since I am at 116,00KM (72,080 Mi) would you recommend I wait another year to replace them?

Thanks for the replies...

My original NGK lasted 170K miles before any misfires appeared. When does your manual recommend replacing them?

 

[andrei3333]

Manual says to do it when the electronic maintenance reminder appears. It does not say anything else like time or mileage. I am just not sure if my reminder has gone off and was reset by my mechanic sometime in the past.

If you can buy your spark plugs through RockAuto they are between $13 and $14 a piece (US).

Spark plugs are typically done on Hondas at 105k.

My maintenance minder asked for spark plugs at ~158,000 km.
116,000 km sounds a bit too early to me...

I wouldn't, you're a bit early at 72,000 miles. I changed mine at 100,000 miles, and from the looks of them, they could have gone a lot more.

If your car is running OK I would wait.

 

[Browngem]

100k and replace. No need to strain the ignition system with old plugs.

That's miles

100k and replace. No need to strain the ignition system with old plugs.

That's also in miles

That's why it's called maintenance.

I am aware. I never claimed they weren't in miles.

 

[Browngem]

I dont think there is a time interval for spark plugs, I guess every 10 to 15 years if you dont put any milage on the car but I don't think they "expire" like tires do after about 7 years or so

I had a interesting experience with spark plugs for 9g Accord, as well as my friends 9g. My car is '14 Sport with about 53k miles on it, my friends a '16 Sport w/ 85k. My friend noticed occasional rough idling, so naturally I suggest changing the plugs. We put together an order for RockAuto, and ordered NGK 'Iridium IX' LKAR7BIX-11S spark plugs. My '14 had about 50k at the time, his car about 80k. Rough idle on the '16 was solved, I changed mine on my '14 due to age more so than miles. My original plugs were quite rusty around the base, and I noted that cylinder 4 there was some oil residue in the spark plug tube.
One thing we did notice is BOTH our cars had longer cranking times first thing in the AM. As example, my car was always crank-crank-FIRE every time leading up to changing the plugs. With the LKAR7BIX-11S, my was crank-crank-crank-crank-crank-crank-FIRE on two occasions in cold mornings. My friend reported the same thing happening with his '16 after I brought it up earlier this week. I also noticed my fuel economy was about 1-2mpg lower than usual. I just changed my plugs to Denso IXEH22TT yesterday, which is the best/closest plugs I could get at AutoZone. I wanted NGK Laser-Iridium DILKAR7H11GS, but they were out of stock. They did have NGK Ruthenium LKAR7AHXS, but I'm unfamiliar with those type of plugs at this point.

 

[WiiMaster]

Laser Iridium is the OE plugs (Denso is also listed as an alternate option), not the Iridium IX, so I'm not too surprised to hear this. Ruthenium plugs are technically supposed to last even longer, and I've seen people use it without issues.

Maintenance minder at 156k km. They still have a good life other than the left most one. My engine have a 5000km/L consumption, so it may have something to do with that cylinder. But still, replacing them at 110k is pointless unless engine have issue.

 

[Browngem]

I would replace them at 100k miles, how much do they cost, $80 total? It keeps from straining your ignition system if you have good condition plugs
