any issue with changing only a few spark plugs at a time?

[Number_35]

I think you may have some more leeway since around the states those go around 100k miles + +

I would have hoped so, but I contacted NGK when their Ruthenium plugs came out, shortly after I did the plugs in the Kia.

They said 100,000 km (probably rounded up from 60,000 miles) for Iridium, and 120,000 km (c. 75,000 miles) for Ruthenium.

Agreed, those are probably conservative estimates.

It’s for my Acura j35!
I don’t know exactly but I know the rear looks to ght but I don’t think it’s as tight as other engines. I think I should be able to bat it out but definetly not as easy a Toyota 2.5L

I'm going to give you some good advice here. Spend ~$18 on the GearWrench magnetic spark plug wrench discussed in this recent BITOG thread. I purchased one in 2017 specifically to change the rear spark plugs on 4 different J35 powered Hondas that I routinely maintain for family members and friends. It makes removing and installing the NGK plugs a breeze. The GW tool is exactly the right length to fit between the rear cylinder head and firewall on the J35 without interference. Once you seat the tool on the spark plug, just add a 3" extension and ratchet to loosen or tighten the plug. It is only slightly more difficult than the front bank.

Thanks a ton for the information !

I wanted to ask, I checked the photo and it looks a lot like the one I got from autozone

Duralast Tools Spark Plug Socket 52-135​

Do you know if it’s the same thing?

In words it’s a 6 inch extension I think with a magnetic socket and a swivel


Looks the same as the Amazon one unless I missed something

That DURALAST tool is slightly different than the GearWrench socket, but should function the same. I just measured mine and it is exactly 6 + 1/8 inch long, end to end. If your tool is much longer than that, it might be a tight fit between the firewall and cylinder head.

I believe this DURALAST Tool 52-132 from Autozone is exactly the same as my GearWrench socket.

I would say generically its likely no issue.

If you mixed new and old on the same bank of a V6, it could be an issue in rare cases. You have one Air/fuel sensor per bank, so if one old plug was firing a little weekly that could contribute to the sensor thinking its running rich, and lean things out a bit - so your other two cylinders might be running lean. Possibly the same if for example you changed 2 of 4 in a 4 cylinder. I would say that would only be the case if the old plug(s) on that bank were really bad, and even in that case it would take a long time to do any real damage.

If you changed all 3 in one bank and left the other, I would think there is no issue / risk at all since they both have their own sensor.

hey all, genuine question here, not trying to troll

today i decided to change my plugs in my vehicle. the engine is a v6 so of course it needs a total of 6

i started the job but it got rainy and cold out of the blue so i only got three done so far

any issue with doing the remaining 3 next weekend?

i will be driving the car during the week etc, as far as i think i doubt it should be an issue since the old plugs were fine and i havent had any engine issues however in case someone is an expert on this stuff i would love to hear opinions

ty!

Maybe if it was a waste-spatk.

ahh dang, yeah i think i actually got the 52-135 which is the one with the 6 inch extension meaning my whole tool is probably 9 inches vs yours is 6 inches as u said

ill prob hop down to autozone and get the other one if i need it, quicker then ordering from amazon and waiting. but regardless thanks for the input

 

[apollo18]

Thanks for the help everyone I had some free time this morning so I just finished it now.

Wasn’t too bad as long as you have a few extensions etc

If anyone could chime in, are my old plugs “bad” per say? Probably in there for 124k miles

Left is front bank ( don’t remember order)

Right side is rear bank ( don’t remember order)

I did a Ford 3.0 Vulcan engine, removing the front row, replacing them with the recommend platinums from Rock Auto but not replacing the back row until weeks later. “ Din’t notice nothing”.

Those old NGK plugs look pretty typical for over 100K miles. I don't see any evidence of oil burning or excessive erosion of the electrodes. The threads on the far right plug in the rear bank photo does appear to have more oil/dark residue than the other plugs but there are no indications of an oil leak into the plug tube as the porcelain is dry.

If you foresee other vehicles in your future get the entire GW set or Ares makes one, too. I also try to have 9/16" for Fords.
