Spark plug BERU or OEM Subaru

Since then I have take good care of it, replaced the brakes on schedule in August 2020 and then in August 2021 new spark plugs.

My 2002 had a similar issue. In my case it was the spark plugs, $250 fix.

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.

I have the beru side firing and they work just fine.

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)

I use Beru Utra-X UXF79 4 tips plugs. It's a great plug for my chipped B6.

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!

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.

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...
