We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

The Forge RS valve has been specifically designed and engineered to offer extreme flow rate capability, where other valves are just not up to it. Often when engines have been tuned by installing larger turbos or even software upgrades improved turbo response can be acheived by fitting the RS valve which has the greater internal mass air flow specification utilising an amazing 50mm (2") bore.

For fine tuning there is a variable spring preload incorporated and a ratchet type top adjuster that will allow for the positive and precise adjustment that your driving style demands. To ease installation a 360 degree adjustable vacuum hose connector. With a choice of inlet and outlet connections the RS valve can be matched to your engine perfectly. This valve incorporates a unique conical, progressive rate spring that can allow for the retention of boost pressure from 7 to 22 PSI depending on the individual user's application and level of adjustment.

If you are intending on running over 22psi then you will need the uprated spring which is included with the kit. This unique spring design will also allow for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring. Other manufacturers valves using cylindrical springs with adjustable pre-load often experience restricted piston travel and flow volume within the normal range of valve adjustment.

Please note: When configured as a Dual- Piston Atmospheric Valve; All Forge Motorsport Dual- Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles, we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.

Forge Motorsport nor any of it’s Authorized Distributors can assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine-management- system, whether factory or aftermarket, is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this.

Please specify valve finish and hose connector diameter

Reliable product made with care
quality has been consistently excellent every single time. It’s reliable, tastes great, and you can tell it’s made with care. What really stands out is how it makes me feel afterward. Even after working a 12-hour overtime shift, I don’t feel as exhausted. It genuinely helps me keep my energy up. Highly recommend if you’re looking for something dependable and effective. I’ll definitely keep ordering.

Look nice.
These were really nice for canned oysters, way better than what we can get in the stores in our area. Perfect for milk based oyster soup! the ratio is one can of cream of mushroom, one can full of milk, one can of oysters. Add butter, salt, pepper, and bring to a boil.

Does the job
Tastes like boiled oysters, so it has that nailed down. I use it in my shrimp ramen noodles sometimes, sometimes I use it to flavor garnish dishes. Best price I could find, but apparently it is a specialty product.

Unparalleled source of heme iron.
This stuff is medicine if your are anemic or have low serum iron. Elemental iron from veggies or pills must be prepared by your body to carry oxygen in hemoglobin. Not so with iron from animals and oysters are unparalleled in iron content. Even if you don't find them delicious you will find them efficacious.

Do not recommend
Edible, though barely. Definitely the worst tasting oysters I've tried of all the brands. Hopefully I don't get food poisoning as has been reported by other reviewers.
