Spark Plugs at 65K

[dattran86]

Change mine out after 85K KM. Plenty of Autocross and Track Day

I must say they do not look that bad.

You can run any plug you want. Check dimensions. It was a weird idea but most big hp cars run plugs that don't "go for" their car. My F80 M3 runs a random plug too. The plug works better for the big boost and race gas. I actually broke a stock plug. These new ones have been fine at 600whp for a while now. Choose your plug according to the heat range you need. Ngk doesn't "make" a spark plug for this car yet mine drives perfect with "Sentra" plugs lol

FYI, I just replaced the plugs on my 2013 FRS for the first time. I'm noticing a slight improvement in initial acceleration, but that may be because they also blew out my incredibly dirty K&N filter.

I brought in my own plugs that I had bought on Amazon a year ago. They charged me $159, after tax.

BTW, It has 135,490 miles on it.

I changed mine around 60k with the OEM plugs and they looked pretty clean; nowhere as black as yours. Could have probably gone to 80k but what's the point. I was doing a bunch of other maintenance in there anyway.

Mine is such a high milieage daily driver and I drive so hard on these twisties that the only thing I wear out is tires - on my 7th set now. But I try to keep up maintenance that affects actual wear of parts. This includes, well, oil changes. It's why I waited so long to replace the plugs. Well, that and I have very large hands, requiring either a lot of time or a dealership . And I don't trust the dealerships.

The dealership I use has one guy in the shop that owns a very souped up Toyota MR2 Spyder and his brother has an FRS with a turbo that this mechanic installed. They made sure he did the work on my car and I'm very pleased with the outcome.

I've learned that if you want to get a lot of miles out of a car (imperative in my case) you keep it as stock as possible. It means you should be doing very little work on it other than maintenance.

BTW, I started to replace my brakes a few thousand miles ago and the pads still had a LOT of life left, so I didn't. Mine is a manual six, and I do a lot of hypermiling and braking with the gearbox.

I got my car used and don’t really know if the plugs were changed at 60k. What is the easiest plug to get your hands on without lifting the engine? I figured I would take a peak at one plug and if it looks bad I will go ahead and order new plugs and lift the engine to do all 4.

Haven't done it myself but from the looks of things the right side is marginally easier.

Don't give me hope that I can skip the 60K service, then tell me no.

I'm at 52,000 right now, and paying to replace the plugs when I want to swap for a 2017 in the next 12 months doesn't sit well with me.

I haven't had any kind of issues starting the car. She runs smooths at all RPMs. I stick with Exxon and Shell gas.

Would we say it's safe for me to wait it out? Maybe push 70 or 80K if it comes to that?

I removed the passenger side front plug fairly quickly and easily. Not a bad job at all. Was even able to get my torque wrench in there. I’m at 84k miles and the plug I pulled didn’t look too bad. The previous owner definitely did not replace the plugs at 60k but they weren’t so bad I’m going to rush out right away and replace them. At least I know they weren’t done at 60k so I can add them to my todo list.

I used a deep 14mm with stuby extension. I had to put the socket in and then connect the extension and then put the ratchet on it. To pull it back out I detached the ratchet, then disconnected the extension. The socket will then be stuck in the hole. I used duct tape folded up and then pressed it onto the end of the socket to then pull it out. I did the same thing to pull the plug out. It took about 20mins from popping the hood to dropping the hood. Again, this is the easy side. I don’t expect the drivers side to be so quick.

Would it make sense to use one of those sockets with the rubber insert specifically for spark plugs or do you think that may make it more awkward?

I used a dewalt drill extension bit to get the plugs in and out since it had a magnet built into it. You can start to thread in the plug with that tool also. Much easier than trying to wrestle a spark plug socket in there, even with the engine lifted 3-4 inches.

I almost did but decided not to because I was afraid I wouldn’t be able to retrieve it due to the fact that you have to pull the extension off leaving the socket too deep to pull out with your bare hands. The duct tape was strong enough to pull the socket and plug independently but I’m not sure it would have enough grip to pull the socket and plug as one.

I plan to go this route when I get around to doing the full job. The duct tape worked okay but was a little awkward. That drop but extension seems like a much better method.

Putting the plug in wasn’t bad at all though. I just stuffed it in there with my fingers and then when you cram the socket in there it lined the plug up nicely. Then I attracted the extension and started the threads with that. Once it was snug I threw my torque wrench on there and I was good to go.

Thanks guys.
I suspected that the plug socket wouldn't be a good plan since they have to line up perfectly. Not doing myself anyway but it was a thought that crossed my mind while reading up on the method.
