Our intake manifold was designed with the latest in CFD flow modeling with designs being optimized around the dynamic flow conditions found inside of intake manifolds. The design looks different than anything else on the market for good reason. Controlling air velocities at every point in the manifold is critical to good flow throughout the RPM range. Nothing in this manifold has constant cross section or tube like features, every curve and cross section was analyzed and engineered for optimum efficiency.

The manifold can either be run with our without secondary shower injection This makes it great for pushing the limits on the stock fuel system while still giving you the option to add fuel later on. The shower injection sprays the fuel down into the individual bell mouths for each cylinder allowing more time for the fuel to phase change and further cool the intake charge, this will really increase the cooling potential for high ethanol blends in flex fuel equipped cars.

There are ample connections to the intake manifold for all the OEM boost reference and vacuum ports plus room for expansion. When adding secondary fuel systems or extra gauges the added NPT ports and included barbed fittings will make everything look like it was designed to be that way.

The modular assembly of this manifold is a unique design feature that allows the ultimate in flexibility never before seen in the Subaru market. The runners, caps and center are separate to allow for future proofing and flexibility. Eventually we will have manifolds for other engines and platforms which makes something like an FA24 upgrade more economical when only the lower runners will need to be replaced and the rest of the manifold is re-used. Also while not on the market yet we are excited to think about things like larger throttle bodies or integrated intercooling as potential upgrades down the road! This manifold will grow right along with the FA platform and what ever challenges your build throws at it along the way.

Love these.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I have them in black and white. I use them everyday in all shoes. These are very versatile and a great quality material. They take a looong time to wear and they stay in place. Very washable and good material. They are not too thick and they do not shrink. I do air dry mine. They do not hold smells even in the summer heat.

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
