ARP Bolts ARP VW/Audi 2.7L Bi-Turbo V6 Head Stud Kit with Washers, 12-Point, Black Oxide - 204-4105

If you’re diving into the world of tuning or rebuilding your Audi 80, you’ll want to check out this ARP VW/Audi 2.7L Bi-Turbo V6 Head Stud Kit. Trust me, these aren’t just any head studs; they’re crafted from ARP2000 material, which means they’re built to handle some serious power without flinching. The black oxide finish not only looks sleek but also provides some added protection against corrosion—always a plus when you’re dealing with the elements.

Now, let’s talk about the design. These studs come with a 12-point head style, which makes installation a breeze. You won’t be fumbling around with wrenches that don’t fit. And yes, they come with washers included, so you’re all set right out of the box. Just to clarify, these are stud fasteners, and they don’t have an undercut, which is pretty standard for this type of application.

What I really appreciate about this kit is how it fits perfectly with the 1988 Audi 80. If you’re looking to boost your engine's reliability and performance, these head studs are a solid choice. They’re designed to hold your cylinder heads down tight, ensuring that everything stays sealed and performs optimally, even under high boost conditions. No cutting or fitting required—just straightforward installation and you’re good to go.

In short, if you’re serious about squeezing every bit of power out of your Bi-Turbo V6, adding this ARP head stud kit to your build is a no-brainer. You’ll get the durability and performance you need without any fuss.

The Story Behind ARP Bolts

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless. 

Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.

What Makes ARP Bolts So Special?

Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes. 

ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.

ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
