Spark plug OEM BMW or BERU
I've been using beru rs7 plugs without any issues.
Pros: no issues
Yup, these are great. Just be sure you gap them to APR's recommended gap of 0.024" ±0.002" or 0.6mm ±0.05mm. If you want 1 step colder plugs, not needed on your setup, but if you do for the future in Stage 2+. For 10$ more than the OEM NGK you can get the BERU.
Pros: great, step colder plugs
I have the beru side firing and they work just fine.
Pros: work just fine
I did track it extensively, probably 3-4,000 km of track use. The only thing it needs is brake fluid and better pads and you're good to go. My car was flawless for the entire time I had it. It threw a CEL right before I sold it that was solved with a simple spark plug change. It never overheated at the track and it was a lot of fun there and very refined and comfortable for highway travel.
Pros: flawless, refined, comfortable
Vehicle:
BMW
I've had much success with BERU plugs on all of my VW's, especially my 16V's. Beru maks the stock/replacement plugs for Porsche, VW and Audi (I work at a Porsche dealership, I see it all the time)
Pros: success with BERU plugs
Vehicle:
Volkswagen
I use Beru Utra-X UXF79 4 tips plugs. It's a great plug for my chipped B6.
Pros: great plug for chipped engine
Vehicle:
Audi A4
Part number: UXF79
I would call New Dimensions... but I decided to go with the Beru Ultra-X. These have 4 nodes instead of just 1 on the head of the spark plug. They are awesome!
Pros: awesome, 4 nodes
Beru Silverstone all the way....Spendy, but worth it, totally. I have taken the pplugs out a couple of times since I put them in a little more than a year ago, and have found very clean plugs, no fouling at all. the electrodes were in the same shape as when I bought them, hardly worn down at all.
Pros: very clean plugs, no fouling, hardly worn
Cons: Spendy, but worth it
i've had the beru ultra x's in for about 8K...no problems...no noticeable improvement either...starts the same (good), runs smooth...no complaints, but no better than stock...
Pros: runs smooth, no problems
Cons: no improvement
Mileage: 8000 km
