Spark plug OEM FORD or OEM Audi

Some weekend progress after work, got the plugs changed out and fresh air filters are in.

New plugs and a fuel filter are all cheap and easy maintenance items that no ones done.

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.

I just fixed a shift issue in my 2011 by changing the spark plugs. The plugs were so worn they were draining the electrical system. Lights brighter and Stereo is louder in left channel now too.

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.

I went 134,000 miles on a set of spark plugs on my 11 Ford Fiesta which is, what, a bit around 215,000 km? They were still in decent shape when I pulled them, just a bit out of gap spec, and I was still getting really good fuel mileage.

Within the last 8,000 miles New spark plugs

Stock Ford ones were $9 a piece at my local dealer…

During a 300 mile trip in 100 degree weather, my car decided to start shaking horrendously, and the check engine light started blinking. Ford Pass notified me of a cylinder misfire. Apparently the spark plug was missing a piece, and there was extensive damage. Metal debris throughout the engine, turbo charger, multiple lines and drains. Everything has to be replaced.. but luckily it’s all covered by the 5yr/60k powertrain warranty. Such a huge failure at 46k miles is disappointing. I love the car but definitely have trust issues now.

I own one of these, and I couldn't have a lower opinion of Fords engineering (the 2v spits out spark plugs? lets "fix" it on the 3v and make it so they will never come out).
