Spark plug OEM Honda or OEM Subaru

Using the muzzler has stopped mine needing the spark plugs changed / having a cylinder go out every 6 weeks.

Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.

im at 95k with the original plugs. no issues

I waited till like 100k to do my spark plugs on my 2013 Crosstrek, they were still good just not as efficient

Just traded in my 2015 Forester with 219,000 miles and the original spark plugs.

Normally that's a result of a failed spark plug seal. If you have no other problems I would put new spark plugs in it and check them at the next oil change.

Yes, a bad spark plug, incorrect type of spark plug, or a wide spark plug gap can cause a coil to fail. If electrical resistance in the secondary ignition circuit is too high the coil must generate a higher voltage to fire the plug.

We just got the 60k service done (spark plugs) and it still does it.

RIP doing spark plugs at home and not hating life.

Good luck doing spark plugs
