Anyone uses cheap old copper spark plug?
Was looking for IZFR6K-13 plugs at Canadian Tire, don't have it.
Googled, and found out that i could just use IZFR6K-11 and re-gap to 1.3mm.
But they are still iridium tip, i'm wondering has anyone here used the basic grade/cheap old copper plug? I think Canadian Tires wants 10$/plug (or was it 10$ for 2 plugs)...
The reason why i want to replace my plugs is that i'm getting incredible shitty gas mileage right now... 400km/tank, roughly 8-9L/100km... granted is winter but still (park in the garage).
So my plan is to do a complete ECU reset (read a post here about it), change the transmission oil with Honda ATF, change oil filter, replace all the spark plug... and hopefully bring the MPG back up... Got the Fit about 2 months ago, zero maintenance work had been done except the dealer did an oil change (which they overfilled by 1 liter).
Car has 80k km on the odometer, granted the plugs should still have 20-40k km to go, but still, i want to get back the advertised MPG right now...

I also go through plugs faster than damn near anyone on this board... So take that as you will.
1.3mm is a big gap though.

I'm kind a lost, because the stock spark plug is suppose to be IZFR6K13, so i look it up online, and the last 2 numbers means the gap size, where 13 = 1.3mm, and 11 = 1.1mm. Although, looking at this page, it says the recommended gap length should be 1.0-1.1 mm...
I am no expert with spark plugs, i just know that if people go turbo and FI they usually go 1-2 range colder to help with detonation. And the last thing i read is that, wider gap would archive slightly better fuel economy and cleaner burn (although, too wide then it might not spark at high rpm).
I'm open to any suggestions/expertise on bring the MPG back to life because 9L/100km i may as well drive my Integra lol... *cry*
So this is my 2007 Fit's MPG for the last 3 tanks of gas... taken the with the 2-4% odometer error..
L/100 km km(corrected) liters
9.52 154.40 149.00 14.186L
7.92 484.80 467.83 37.055L
9.36 405.30 391.11 36.593L
Second tank of gas i drove like an old man, trying to keep the rpm needle under 2.5k, 3rd tank i said fuck it, i will just drive normally, which in most cases, the needle never went past 3k.
PS: The Fit is Automatic, i know MPG may suffer, but i hope NOT THAT MUCH... I had a 1992 automatic Integra before and it did ~9L/100, and it was with a B18A...

There's really nothing wrong with using copper electrode plugs; they just 'wear out' and need changing more often. And when the feds require that 50k mile warranty manufacturers don't take chances. Cost too much.
