- Could you please expand on your experience?
-
- Mine has been JUST the opposite.
-
- Fact: factory recommended replacement intervals for platinum plugs
- in Toyota products is 50,000 miles (just enough for them to
- eliminate replacing them under the federally mandated emissions
- warranty requirements)...
-
- Fact: I have personally run NKG platinum's in Turbo Supra Toyota for
- over 60,000 miles with NO measurable change in plug gap, and
- no performance problems...
-
- Fact: factory recommended replacement intervals for non-platinum plugs
- on Toyota products is 15,000 miles.. and I have measured
- considerable changes in the gap (typically +.001" per 5,000
- miles).
-
- Fact: Given that you can generally purchase platinum plugs for 2 to 3x
- the cost of regular plugs.. they become cost effective on their
- replacement cost/vs interval alone.. and when you consider the
- amount of labor required on many automobiles to replace the plugs,
- they become VERY cost effective due to the decreased replacement
- intervals.
-
- Maybe Fact: It is claimed that due to the smaller (typcially) electrode
- size of platinum plugs vs regular plugs that firing voltages
- are less.. makes sense to me, since high-voltages typically
- are attracted to point contacts (ie: look at a lightning rod).
- I may have read some technical stuff on this a long time ago..
- but do not have it at hand, so this becomes a "maybe fact"
-
- Again.. would you expand on your experiences?
