here's a general question, not relating to the 8

My igintion coils have over 100,000 miles on them, Will I notice a performance improvement if I were to replace all of them for the same ones?

 

you should

 

When you pull them off please post a photo of the underside of each one.

 

You got them to last that long? Amazing. My were choking at 35k. Yes, you should replace, pretty easy DIY job too..

 

100k holy ****

 

mike i thought you were getting a boxter!!!

i have a set that has 80k miles on them still going strong.. when they go you will know it..

now the new ones are supposed to be better. and for 4 it is like 110 bucks.

beers

 

What kind of gas mileage do you get?

 

This question is relating to a GM product everyone!

anyway, I changed the coils with the spark plugs so I dont know if it made a difference or not. But my butt dyno tells me my truck is just as fast in the straight away as the 8

 

After doing some research on a used boxter, a rather get a new Rx-8 instead. From what I found out, the boxster is going to "leak" sooner or later between the transmission and the engine, Reparing it is going to be very costly. And besides the performance isnt that great vs the Rx-8 anyway!

 

Plus no room to move on the inside.

 

ah... the porous (sp?) metal issue..

 

Seeing that a coil is actually a wire wound tube.....it should not ever go bad unless the workmanship/quality is bad.

 

5 year bump...wow!
