Changed my plugs after 38k (PICS)

[bronsin]

The plugs went 150,000 miles in my wife’s Camry. The new ones didn’t make it run any better the old ones work just fine.

The accessory belt and 150,000 miles on it also before I change it. The gauge I got said it was not worn at all. I could nt Bear to throw it out.

I have found going longer distances on plugs causes other problems that may or may not be apparent right away... In the old days it would burn rotor and cap due to excessive secondary resistance...NOW it causes coil packs to get hot and burn out, due to excessive secondary resistance...

I always keep the old belt in the back (along with a few tools to do the emergency change) but once they start drying out/squealing/cracking...time to kick it out, I would rather NOT have it crap out along side the road, because I was too cheap/lazy to do preventative maint.

Can you elaborate?

Just hit 175k miles on my original plugs. Car still seems to drive the same and get the same gas mileage so I haven't bothered changing them.

I have never had an issue not using anti-seize on plugs. My Yaris has 300k on it. I'm on my 2nd set of Denso Iridium power plugs. Oem plugs I took out at 100k. Installed the first set of Denso's and took them out at 200k. No seizures yet. I've not used anti-seize once since my first spark plug job in 1992. Not one seizure on many of my platforms, 80's rx-7's, 90's rx-7,s, 90's supra, 90's Landcruiser, 90's Toyota pickups, 90's dsm's, 2006 merc amg's, mitsu gvr4's, Cressida, 90's skyline gtr, Lancia Integrale, 2004 Mitsu Evo, the list goes on. You do not need it. It also reduces the sparkplug grounding connection.

Well, To each their own.
I have been using anti-seize on plugs for 35 years, and have had ZERO problems, I would strongly disagree with the theory that it inhibits grounding of the plugs...My Ohm Meter also disagrees.
I am just stating what works well for me... And Preventative Maintenance is better than a tow bill.

I am in same dilemma

I have DENSO SC16HR11

Looking to replace

I viewed with techstream misfire on cylinder 1

IS NGK is better than DENSO ?

I changed the spark plugs on my wife’s 2005 Camry at 150,000 miles and they looked perfect in the car ran perfect also. I think it was $40 for the iridium plugs.

Totally unnecessaryIn my opinion. But I would recommend removing the plugs so they don’t become seized. I would say 50,000 miles to remove and reinstall plugs is a good idea. I think I also put anti-seize on the new plugs I put in. If the plugs seas and you stripped them removing them that wouldn’t be good.
