BMW S55 Engine Pro-Series 18.8 Cylinder Head Stud Set


Replacing the original cylinder head screws with high-strength Pro-Series 18.8 studs.
This is necessary when making large increases in performance, as the original cylinder head screws elongate during operation and the cylinder head can lift off.
The Pro-Series 18.8 stud bolts with a tensile strength of 1850 N / mm² provide a solution to this.

In addition, these stud bolts do not have to be replaced after dismantling, but can be reused.

Technical details:

  • Manufacturer part number: P102081410
  • Kit content: 14 stud bolt (M11) / 14 nut (M11) / 14 washers / assembly lube/ assembly instructions
  • Tensile strength: PS 18.8 steel / 1850+ N/mm² (270.000+PSI)

The Pro-Series 18.8 sets are high-strength stud bolts manufactured in Germany.
A special steel is used which, after tempering, has a tensile strength of 1850 + N / mm².
All threads are formed and not cut as usual. The so-called rolling of threads can increase the strength of the tooth flanks by around 30%. All Pro-Series products are supplied with a nickel coating or optional with a burnished protecting against corrosion in the long term, even under the toughest conditions. Pro-Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Due to a cone on the engine block side of the bolt, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads when racing engines are frequently rebuilt.

Pro-Series advantage over other manufacturers is the nuts and washers included in the set, these also have a tensile strength of 1850 N / mm².

High quality french press
I really like this french press. It is made from high quality stainless steel and does not rust or show signs of degradation. Easy to take apart and clean. Everything fits and works properly, the filters work fine. It stays hot for about 3 to 4 hours if filled to capacity.

FIRST use of ziruma french press
This is a great, clean French press with no plastic parts at all. The filter mesh is excellent, and the brew comes out very clean with minimal sediment. Quality: Good but not superb. There is visible welding on the handle (see attached picture). I was expecting it to feel heavier overall — especially the lid, which weighs only about 180g (6.3 oz). Thicker walls would make the pot heavier and give it a more premium feel. The lid could really use a lock or twist mechanism to hold it securely in place. With this one, you have to hold the lid down when pouring out the last bits. All in all, it’s a solid French press that works well for daily coffee use.

Definitely worth the money, Great Product!
Looks great, well built, very solid! Easy to use. I’ve used the glass French press coffee makers in the past and decided to switch to this one. I’m glad I did, the coffee stays hot and there is very, very, very little sludge at the end!! I just wish that I didn’t wait as long as I did to make the purchase! Definitely worth the money! Great buy!

AWESOME!
This is my first time using a French Press for coffee, and I chose Ziruma for its looks and durability. It's beautiful and works even better. No coffee grinds, just smooth, robust coffee that stays hot due to its double-walled design.
