my plugs are only lasting like 5k miles, is that usual?
they look fine, just they are rounded around the terminal (loss of power, etc, fixed with new plugs)

mods in sig

 

5K is a little early without a CDI... what are you using for an air filter???

 

some cheap steel mesh cone that came with the car

 

Sounds about right to me. Possibly a bit early, but a lot of people like to replace their plugs every 2nd oil change, which is generally 4k-6k miles.

What kind of driving do you do? Mostly city driving will turn the engine a whole lot more in 5k miles than pure highway driving.

well things that increase plug wear are :
1. The amount of dirt getting into the engine (in otherwords cheapo air filters)
2. detonation
3. high voltage
4. wrong temp plug for the conditions driven

 

That's normal.

i thought it was around normal. got 8mm racing beat wires too, so i figured maybe a little earlier demise to the plugs.

im like 50/50 city/highway too

just wondering thanks guys

 

Spark plug wires have nothing to do with spark plug life or performance.
