I want to give a huge TY to those who have given their comments/suggestions to me on this sparkplug/wire issue I'm having. There was no shortage of those on last forum I was on though, a few more would be appreciated here though!

Copper is simply more conductive and will give the most reliable spark. The downside is it wears much faster than iridium or platinum. The copper is most advantageous when running smaller pulleys which create more boost and more turbulence in the cylinder. The spark is less likely to be blown out. If you are using stock pulley it is perfectly fine to run stock plugs. You can certainly use copper plugs just be prepared to change them every 15k miles or so.
Once you have done plugs, wires, fluid changes, etc there is not a whole lot more you can do to get better mileage. The air filter should help. Make sure your car is aligned and keep tires at proper pressure. Some even over inflate them a couple psi to get better mileage. Make sure your brake calipers are in good shape and pads aren't dragging. Bad wheel bearings can hurt mpg.
But after all that the #1 mod for better mpg is the right foot mod. Stay out of the gas, keep rpms down and drive like a grandma. Or just enjoy your car and accept the fact that you aren't driving a Prius:)
That's what I was wanting! All in 1 email too. Tyvm!Quote:

I filled it up w/ 87 octane last time, but I've been advised by this forum to only use 91+ octane, correct?Quote:

I'm running E85. Mileage is not my end goal lol. Would hope I can improve it eventually though.
Yes, use what your manual tells you to. You have a big hot air maker bolted to the top of your car. Engines don't like over heated air in the cylinders. Too hot and you get pre detonation. Too much of that and bye bye engine. 91+ octane helps combat that.
If you want to run 85 octane then talk to Overkill about a custom tune. You will lose power but it can be done. Or....buy a Prius.
If he's running e 85 then it's over 91+ octane.
E85 is an ethanol/gasoline blend (85/15) not an octane rating.
I meant 85 octane petrol.
I wasn't given a manual with the car. So 91+ octane it is. TYVM!

Just curious, if I was driving down the interstate with the CC on @ 70 or 75 mph how much better of gas mileage should I expect to get with my new air filter installed?http://images.tapatalk-cdn.com/15/06...06aca7adfd.jpg

Probably wouldn't notice a increase, you should of saved your money n just made your own simple fwi intake.

And I just started doing pcm's for the 04 too. ;D
No need on the 91 octane , you can run regular 87 Octane if you want to just drive the car, and not race it. If you look at the manual for the 2004 GTP you will find that is states that you can run regular fuel in it. I owned a 2004 Grand Prix GTP and ran regular fuel in it and it ran fine. If you want performance then yeah run the higher octane. The Series III engine is very nice, I had no issues with it and the gas mileage was very good if you just wanted to drive it like a normal Car. The aftermarket air filter is very good for the engine to breath better, it helped mine a lot. I sold my car as Wife wanted a newer one so mine went down the road.
