Didn't say bad; I said that significant anecdotal evidence indicates that the ECU in the Tundra does NOT like to work with the Bosch units. I'm not an engineer, so I can't tell you why. You decide whether you want to gamble on a German component in your Japanese vehicle.


If all you did was swap plugs, then something is distinctly wrong. You either have used an inappropriate plug, or your gaps are off.


You are correct. It IS electronics. And they rely on a certain set of expected behaviors that correlate to its operating rule set. When there is deviation (as may be expected with non-OEM electronics), then unsurprisingly there will be operating problems.


You are correct. They have electro-ceramic components that wear during use. But the OEM Denso and/or NTK units have an expected operating life of 100,000 miles in normal service.

nice sig see you received my PM
