Haha... I struck a nerve!

How about an even older, say, O-170?

Here's mine at 60k, yeah maybe not necessary to change unless it's been run harder than mine has. I changed 2 fried coilpacks at the same time and the car definitely feels better, but that likely has to do with the coilpacks more than the spark plugs.

I can see a bit of wear on the ground electrode not evident on the new one, I certainly wouldn't recommend pushing the replacement past 100k. I'll be replacing them again at 120k because I like my car and it doesn't break the bank.

2 fried coil packs? Is this normal? Kind of puzzled. Is this by design or by lower quality?

I thought it was from track use but I just learned that tracking is no more stressful on a vehicle than daily driving.

The codes only happened during track days for me, I think once or twice they appeared on the street, none during autocross. I lived with them for over a year, might have been close to two years or more, I'm not good at record keeping.



If you plan on doing track days it may be a recurring issue, if not you're probably never going to experience it. I can only speculate as to why, however there are several newer part numbers that have been created to replace the old parts so I can only assume it was a surprise oversight. This isn't the only car to require coilpack replacement, good old Ford V8's from about 15-20 years ago were a bitch and the RX-8 is pretty much on 30k replacement interval iirc.

And the reaction from truckers looking down into the car is PRICELESS!


Actually it stands for Big Ugly Fat F Driver

As Clint said "A man has got to know his limitations."

Big man, tiny low powered car... what does THAT mean?

Ah yes, my first engine overhaul under an A&P's supervision at age 16 (then mounted in my first plane, a junk Ercoupe I bought, rebuilt n got my license in). But then we called it an A65, not an O-170

I was a kid around Cubs. I just knew it as the Continental. It was either that or the Lycoming. Everybody shit on the Lycoming.

Well that because so many people had the push rod tube seals take a dump and start leaking oil... reputation well deserved! Or one L I hated where the cylinders just would not seal to the case even after case being reworked and different exchange cyl set.
Actually it's hard to tell the difference between older models of C or L nowdays because they both got their act together better.

Like the plugs for our cars now, the lifespan n performance is awesome and makes up for the difficulty changing. People today are spoiled because used to be you had to change plugs on an average of 10,000 miles, give or take some. (and points, condenser, and distributor cap)

I was a kid but, you know, the issue with the pushrod tube seals sounds familiar.

Oh, and I remember the days of gapping points & plugs, setting timing without a strobe, etc. etc.

Lol change them!! E85 fouls plugs faster. Switch to an iridium plug. Will help them last longer. These ngk plugs worked great on mine. Part number PLZKAR6A-11

The stock Densos are iridium-tipped.

The car hasn't had any sign of problems yet. Just took it on a 1200 mile, 26 hour drive, 400 miles of it being stop and go traffic. And going back the other way tonight.

You sure it is going to work? Even on NGK's website, it is only for Sentra.
