Spark plug OEM Toyota or OEM Volkswagen

O drove my Corolla to the point the spark plugs weren't firing and the car wouldn't start. I changed the plugs and it ran great after that.

Maintenance: 39th Oil Change (every 10K) and Tire Rotation, 13th Engine Air Filter, 13th Cabin Air Filter, 3 brake jobs, 3 coolant flushes, 2 spark plug changes w/carbon cleaning, no suspension work, no transmission service, 1 Break Down at 280K Due to a Design Flaw In The MGR Cable Which Powers The Hybrid System $5200, cat issue at 380K due to bad gas, no hybrid battery replacements in case you were wondering, does not consume oil

UPDATE: owners manual calls for replacement around 120k so I'm not that far behind i guess. Still went out and bought 4 new plugs and installed them. $80 at the dealer

Noticed before the LTFT was -6% and now its back to 0%.

I changed all sparkplugs now my vw is running great. make it's the correct sparkplugs.

Those look great last time I did mine they were all carboned up but I was at 300k but definitely made a difference in Fuel economy and a little less sluggish

I’ve owned my truck for a year now and just decided to take out the spark plugs to see how old they were… mfs were the original factory plugs 14 years old and ran for 246k miles.. basically got a brand new truck now haha

And also removed and cleaned my spark plugs. All these collectively seemed to have a great impact on the engine\u2019s performance! The engine runs much smoother and feels a lot more sporty!

New plugs and coils went in and the misfire is gone. Sounds healthy too.

I’ve done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!

I was given an "offer" to have my spark plugs changed for $368!
