Spark Plugs
#1
Simple question...what basic spark plugs should i get for my focus? 1 step colder Motocrafts?

or whatelse is out there thats good and basic

just doing some maintenance on the car....spark plug wires,fuel filter, gonna clean my flat K&N filter, chance oil (add injector cleaner as always)

for some reason im gettin crappy KM's ....430km and thats mostly highways

could it be that my engine is tuned to crap?

stock plugs are best for a stock motor, you only need colder plugs if your boosted. Stock plugs should last at least 50K.

i got better mileage, and response from my focus after i changed over to copper core from the platinum plugs that came stock. it is more maintance to go with copper because you have to check and replace the plugs more often.

a lot of people on FF use the autolite 104 copper plugs and gap them to 0.55'' thats supposedly the better range. as far as im concerned the stock plugs which are good for like 100K (not 50K lol, at least thats what the manual says..) are probably good enough. a spark is a spark its not like the motor can tell the diff, for fuel economy, fine but replacing the copper plugs vs the gained mpg would probably balance out. i get 450kms to the tank all city driving, so if yours is mostly highway it should be well over 500kms. if we get a dyno day like last year im for sure going to test both sets of plugs the copper vs stock plat and see which yeilds more hp, if any.
Little bit of show, little bit of go.

Hey Nik learn from my mistakes man. If you are not going to do any turbo/charger work, then stick with Ford stock.

I've learned my lesson. From now on i'm not going to be getting anything else but original.

I can "run it up" on the Duratec with stock plugs and I've never had an issue yet (26,000KMs on the weekend). Then again, I'm Coil-on-Plug so that changes things a little. I'd work everything back to the distributor in your case, gradually, to sort it out.

Zetecs have a coil, right? I know I changed one in the SPI to sort out a massive issue a few weeks before I sold it and it made it run MUCH better.

the copper plugs need to be replaced twice as often as platinum plugs, and if you're unboosted, you're not going to see any benefits really.

You can pull your plugs and regap them if you'd like, but I wouldn't suggest switching plugs or wires since the aftermarket ones tend to miss out in the reliability department and offer little (if none) performance increase.
