Spark plug Champion or OEM Toyota

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

You can get the champion version of the RS7 plugs for less than $20 a plug and they’re working great on my car!

These were actually alright spark plugs. The ceramic is a lot tougher than normal ceramic, and the electrode is larger. They were marketed as 'truck plugs', but they're really good in old tractors and farm equipment. They last forever.

For spark, I wasn't sure I had the right plugs so I went with the OEM Champion plugs that were recommended in the Bentley. I checked for spark, no issues there.

I was looking at pictures of the V12 engine found in the Toyota Century. Then I noticed the spark plug/coil arrangement: Interesting.

I once had to use 99 cent Champion plugs in my car for a few months when I was flat broke. They worked fine but didn't last long.

Champion is shit for cars. Leave it for mowers and weed eaters.

I would return them and get Motorcraft anyway. Champion is garbage.

Champion plugs are barely adequate for a lawnmower...
