Spark plug Motorcraft or OEM Audi
Reviews
Some weekend progress after work, got the plugs changed out and fresh air filters are in.
Pros: fresh air filters
Vehicle:
Audi RS5
ive been using the RS7 spark plugs(Gapped properly) and swap every 10k miles, but nowadays I do not run very hard, just cruise and occasional hard accelerations. Paired with APR coil packs, havent had any issues.
Pros: no issues
Vehicle:
Audi RS7
Mileage: 10000 km
Oem Motorcraft plugs are always my go-to. They generally last around 80k miles.
Pros: last around 80k miles
Vehicle:
Ford
Mileage: 80000 km
120k miles on my 2015 a3 with a stage 1 tune. I did timing belt, tensioner, and water pump around 100k miles. Costed me like $1k. Also did spark plugs and a new battery, which was another $600.
Vehicle:
Audi A3
Mileage: 120000 km
Modern Ford engines tend to work best with Motorcraft or NGK spark plugs.
Pros: works best
Vehicle:
Ford
Within the last 8,000 miles New spark plugs
Pros: new spark plugs
Vehicle:
Audi A6
Mileage: 8000 km
Motorcraft is all I use , heard to many stories about aftermarket plugs causing misfires
Cons: aftermarket plugs causing misfires
I do run Motorcraft plugs because they seem to crack a little less than the Autolites.
Pros: less cracking than Autolites
I heard from an old ford mechanic once that ford designed their ignition system around the motor craft plugs and no other brand plug will run right if installed. Since then only motorcraft or autolite in my fords.
Cons: other brands won't run right
Vehicle:
Ford
Iridium plugs suck on fords.
Cons: suck on fords
Vehicle:
Ford
