- my motor is a 94 1.6L DOHC with ATX.
I have seen a dramatic power increase since then and the motor is running fine - But a mechanic told me that these plugs are very powerful and produce a lot more combustion and hence might damage the engine/tranny. I have learned enough to not beleive what mechanics say - but i want to confirm this just in case. Does anybody have any info on this - should i take them out and put some NGK's in there or is this fine.
Also what do you think of this Bosch platinum +4 thingy -
