Wagner Tuning Cylinder Head Stud Set - Audi / 200 2.2 20V TurboAudi 5Zyl 20V 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 mm provide a solution to this. In addition, these stud bolts do not have to be replaced
Audi 5Zyl 20V Pro-Series 18.8 Cylinder Head Stud SetReplacing 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 / mm� 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: P101051210
Kit content: 12 stud bolt (M11) / 12 nut (M11) / 12 washers / assembly paste / assembly instructions
Tensile strength: PS 18.8 steel / 1850+ N/mm� (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 / mm�.
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 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 / mm�.

Make sure you read the terms and conditions and don't let them off the hook
Asurion is counting on the fact that you don't know how to read. They made the claim process aggravating and as difficult as possible. I CAN read and had to review the terms and conditions with them on the phone and threaten to involve an attorney before they would honor the coverage. They tried to say my product was not portable, when the word "portable" is literally in the name of the product. Then they tried to say the the accidental drop was not covered, but it clearly states in the terms and conditions that an accidental drop and a cracked screen is a covered event. I buy the coverage almost every time I am offered it, but I will be rethinking that going forward and Amazon should consider finding a different company to issue the protection plans for their products because I fear this is the beginning of a lot of complaints. I have filed a claim in the past and it was very straightforward and easy, but they must have a new company managing the plans now, because it was anything but easy. If I was an older person who was not tech savy, or who just took someone's word at face value, I would be out the cost of my item and the protection plan. BUYER BEWARE

Cover yourself!
My HP printer just stopped printing. Spent over 4 1/2 with HP Support doing all kinds of technical experiments with even the most complex Factory Restarts, this printer kept saying everything was working but it wouldn't print. HP finally declared it a hardware defective; told I needed a new printer and to recycle this one (less than 1 1/2 years old - don't make like they used to!). Called Asurion, who immediately processed a claim and arranged for a pickup of the defective printer since I can't drive. Fast quality service worth every penny if you're buying any kind of devices in today's world.

Asurion is a great protection plan.
Asurion is a great product. I purchased a 3-piece cordless phones in 2022 and added the Asurion protection. Just recently the phones went out. I contacted Asurion and within 2 hours I had a gift card deposited in my Amazon account. I purchased new phones with the gift card and of course added the Asurion protection. I highly recommend Asurion protection plan.

Glad we got it! And will most definitely buy it for our future products!
Great experience! We always bought Asurion Protection on a lot of our electronics to be on the cautious side. We recently had one of those electronics give out on its 3rd year, and we luckily had purchased the Asurion Protection Plan. The claims process was easy, took less than 5 minutes. I packaged the electronic the following day and dropped it off with the shipping label they gave me. I received a full refund of my product within hours of having the returned item dropped off. I am glad we bought Asurion Protection for our other electronics, and will continue to buy it for our future products (not just electronics). Very pleased with how fast and reliable they were, and enjoying the comfort of knowing our products are protected.
