Plugs after one year

[Poppavein]

I was concerned that you only use Shell.

There used to be a concern that fuel additives can eventually build up deposits. It was recommended to occasionally change between companies which allows their fuel cleaners to clean out the deposits from the other companies.

Is this an urban legend?

I haven’t read all the comments so if this info has already been shared my apologies. What the plugs look like depends on when you pull them. Ideally to get the best indication of your engines tune/performance you want to pull them after the engine is at operating temp and after driving and then shutting the engine and pulling them. Low rpm/idling and city driving will always result in more build up on the plug.

On average, you're conservatively talking at least 200,000,000 spark ignitions per plug over the life of the plug. That's before the electrode is completely worn, only after it has worn to its expected service life. Spark quality is going to be essentially the same at the end of service life as at the beginning--at least within ignition tolerances.

Personally, I would not risk running a hotter plug in a turbo-charged engine, especially if I'm not always using premium fuel. The chance of detonation is much greater, with no reward to be gained when the correct plugs are already operating perfectly. If I were OP, I'd put those plugs back in and not think twice about them for quite a while.

very good advice.

very good advice.

yep, lots of great takes in here.

I probably bought into the hype of colder plugs needed with higher boost/temps, but you're all right, probably not the case with my meager mods.

TBH, I've been chasing the feeling of wanting a more responsive pedal from day 1. All of the mods I've done have helped, but it's just a feeling I can't explain. There are a lot of threads out there with other owners describing the same thing, even those who have had the Procal tune, which certainly helps, but doesn't alleviate it all the way.

My guess at this point is that it's just torque management from the transmission. I should just stay in Sport mode all the time or just get a sprint booster, I suppose.

Yeah, but you did an LS swap, right?

Negative. That would be fun though!

I recently had the dealer change mine for $387 back saving bucks. 45,000 2.7. Saw a Ford tech on Youtube saying around 40,000 you might experience a slight hesitation. And that's what I noticed. Everything was fine. Gas mileage still very good. Just a very slight hesitation a few times when giving it sudden juice.
Fresh plugs and it feels like new. Now if the price of premium would go back down... Because it's fun to drive. Anywhere.

One of the easiest plug changes (2.7) I think I e encountered in a good while, especially on any vehicle newer than the turn of the century.
From walking up to it with the tools until closing the hood was about 30 minutes.
Not suggesting we go against manufacturer recommendations, not suggesting anyone throw money away, and definitely not suggesting plugs need changing with low mileage engines.

I’ve wasted larger sums on dumber efforts.

Agreed. I just swapped in the Ruthenium plugs bought from @ZFGracing after checking with them and here about them vs the NGKs I’ve had in (bought from Panda) for 2000 miles. Big difference in idle, launch and everything. I was kind of shocked. Same gap 0.026.
