ARP is the go-to manufacturer in the automotive industry for engine fasteners. Whether it be OEM replacement parts or custom hardware, their dedication to consistent top notch quality has made them a favorite in the racing world.

These ARP head studs for 06A 1.8T engines are made from premium grade 8740 alloy steel which is rated far superior to many "aircraft quality" competitors. The studs are heat treated to 200,000 psi then thread rolled afterward, giving them twenty times better fatigue strength over studs threaded prior to treatment (a common practice with lesser quality studs). These high-quality head studs will ensure your headgasket stays firmly planted under even the most extreme boost conditions. These parts are manufactured in the U.S.A. and are 100% re-usable.

The 06A 1.8T engine is a tricky one to make studs for because of the very tight access to the nuts. ARP has finally launched a stud kit in addition to their bolt kit for this engine. The studs offer easier assembly, and are only loaded with minimum torsion when they are tightened. This makes them even better in that they achieve the required clamping force more reliably. The downside is they do cost a bit more than the equivalent ARP bolt kit.

Quick solution to replace that OEM Plastic Mount in your BMW E90
Effective Upgrade: After installation, I have experienced no leaks, which is a significant improvement for my vehicle. Quality Material: The aluminum construction feels durable and sturdy, offering a long-lasting solution compared to the original fitting. Cons: The installation process was a bit tricky. The holes didn't line up perfectly, making it a challenge to fit. While there was no need for drilling, finding the right angle to fit it required some patience and effort. Wider holes could have made the installation easier. I rate it 4 stars because of that. Despite the challenging installation, the Aluminum Water Hose Fitting Upgrade is a worthwhile investment for anyone experiencing leaks. The improved performance and durability make it a recommended upgrade for BMW E90 owners.
