my issue has always been when the fuel level is low.. it takes a little more cranking.. and when it's full .. it starts up right away.. but i keep thinking to myself that this can't be because the pump is always gogin to prime no matter what
As far as the fuel level issue goes, consider this: Your fuel pump produces a pressure difference, not a constant outlet pressure. If your gas level is high, you have a higher starting pressure, and thus a higher outlet pressure. Hope this makes sense.
the ignition system in a car is designed for a 1 spark per 4 cycle motion.. the only time you would see a differance is if the car demanded it.. i think my teacher told me that most people with the multi- spark ignition system is waisting their money because the car doesn't demand it.. just make sure it's getting 1 good spark to ensure combustion and call it a day.. plus you wear down the plugs faster..hehehe
i don't know how much iridiums are .. but i run ngk coppers in my si and just change them out every 15k
Any comments on NGK iridium plugs? i didnt notice ne performance gains nore fuel mileage
i personally think they are a waste of money. i would rather just save the money use non-iridium and change them out more often b/c i think it's healthier on the car anyhow.
Iridium IX are not that expensive. I noticed a little. Btw, what kind of battery are you using. Some batteries, produce a higher cold cranking amps than others.
