Alloy Atmospheric Ram Dump Valve, flange mounted available to fit the Impreza V5. Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound most commonly associated with rally cars when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

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 Authorised 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.

 

In The Box:
1 x FMDVV5012 Valve
1 x 28mm Blanking Plug
1 x Forge Sticker

Good value for a $55 boot.
Size: 12, Color: Army Green
I like these boots because I have a wide foot and even though I bought the 12 and NOT the 12W there is plenty of width. Very comfortable boot. I have put this pair through about 1000 miles mostly on asphalt, ice and snow. Very little actual dirt/ rocky trails. I bought them for the waterproofness and ankle support. Now the soles are getting thin and I can feel small rocks through the soles. Plus the soles are beginning to separate from the uppers and they are no longer waterproof. Not bad for 1000 miles. Still, I feel For a $55 boot they are a good value. I am 6ft and weigh 250.

Worth Every Penny!
Size: 9, Color: Coyote
I absolutely love these boots! They are super light, comfortable and definitely waterproof. I took them on a camping trip for the weekend and I walked through creeks and puddles with no issues at all. No water got inside and they were comfortable all weekend. The only thing was the tongue did start to bother me a bit after the 3rd day. I have some pretty boney shins but a small cloth between my shins and the tongue helped a lot.

Excellent boot for the price! Very solid. Cushy insoles very comfortable. Wide width plenty wide. Recommend getting half to full size smaller than your usual.
