Integrated Engineering is proud to bring you this very high quality valve spring kit for VW 2.5L I5 engines. This kit features spring rates which are optimized to match your vehicle specifications and provide proper valve control even under high revving applications.

Increasing your engines power output often comes with modifications that require more RPMs to get the most out of it, such as larger turbochargers, tuned intake manifolds and bigger cams. Upgrading those components without changing out the valve springs can leave you with a short power band or cause valve float and other significant damage.

Cheap valve spring kits are often designed by simply finding a spring that is stiffer and will fit. Those are also not usually a good compromise because many times they are the wrong stiffness, and often poorly constructed. A broken valve spring can cause total engine failure and destroy everything that you have put hard work and money into. Our kits are designed hand in hand with our camshafts. They are the only spring and retainer kits on the market designed by someone with a working knowledge of the camshafts in these engines, and what the spring requirements actually are.

Manufactured out of the best spring wire in the world IE valve springs use a patented multi stage shot peening process that further reduces failure rates. Our titanium retainers are machined with an excellent surface finish and tight tolerance control for a long lifespan. Each application is thoroughly tested to perform on these engines right here in our test facility in Salt Lake City, Utah. Our spring and retainer kits are the best matched, most tested parts on the market. Purchasing a set will ensure that your engine runs at maximum performance and reliability.

Kit includes:
20 precision wound intake/exhaust valve springs
20 Titanium intake/exhaust retainers

Features:
Engineered, designed, and manufactured in USA
Nan-peened for long life

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
