Best Spark plug for Ford Focus
I love my brisk spark plugs from EMS. Definitely better for me than the NGKs I ran. Last longer and don’t open up as fast.
Pros: last longer
Cons: open up fast
Vehicle:
Ford Focus
I recently changed my spark plugs on 2012 Ford Focus. I used Bosch and got a 3 MPG boost.
Pros: 3 MPG boost
Vehicle:
Ford Focus
I run NGK on my 15. The car runs great doesn’t miss. I used OEM Denso 5339 but they lasted 10-15k but then I tried NGK 92182 and they’ve lasted bout 40k so I’ve had no issues with them both of them Iridium.
Pros: car runs great, no issues
Cons: Denso short lifespan
I still put a small dab even though the NGK plugs recommend against it. I change my plugs every 15-20k because I have a tuned Focus ST. I already went through 3 sets of NGKs with no problems doing the small dab
Pros: no problems, small dab
Vehicle:
Ford Focus
Mileage: 20000 km
I ran stock plugs for a while and they got chewed up fast. On NGks now and even pushing 29 psi they keep the gap well.
Pros: keeps the gap well
Cons: stock plugs chewed up
Vehicle:
Ford Focus
Until I replaced the plugs, coils, alternator, starter, battery and cleaned connections all I could, this problem persisted and my vehicle killed a coil / 2 every season.
Pros: cleaned connections
Cons: vehicle killed coil
Vehicle:
Ford Focus
For the intake i would recommend k&n filters systems, racing plugs are not even worth it, better look it up some NGK iridium
Pros: NGK iridium plugs
Cons: racing plugs not worth
Vehicle:
Ford Focus
So, I changed spark plugs in an old Ford Focus 2001. And currently there's no way I can get the original Motocraft spark plugs, so I bought and installed the NGK ones which are supposedly compatible with my vehicle. I used them a week, but since the start I noticed great differences in size in the threads and in the shape of the head. Is this a problem?
Cons: size differences, shape differences
Vehicle:
Ford Focus
I bought some NGK from RockAuto and they only lasted me 15k miles. I just ended up buying the FoMoCo ones from the dealer.
Pros: easy to buy
Cons: short lifespan
Vehicle:
Ford Focus
Mileage: 24140 km
