Snow Performance has combined performance, quality, and easy installation in this new water-methanol injection system engineered specifically for all N54/N55 Engines. Increase your pump gas octane by 25 points and make more power efficiently with a cooler running motor! Complete with custom water-methanol injection throttle body spacer plate, braided stainless line, and 4AN fittings offering un surpassed reliability and ease of install. The Stage 2 uses a progressive VC-50 controller (ISO 9001 Manufactured) that proportionally injects more or less according to boost pressure. Start and full points are adjustable for engagement and delivery curve to match what the engine requires. Proportionally injecting according to boost pressure gives an accurate delivery of water-methanol and allows cooling and performance improvements over a wide range for improved drivability. The VC-50 controller (52mm gauge) offers the functionality of a boost gauge and water-methanol controller all in one! Highlighting a 7 color (Blue, White, Red, Yellow, Orange, Purple, Green) OLED screen displaying boost, percentage of injection, low level, secondary nozzle activation, prime button, and 2 fault codes directly on the screen you can tailor the controller to match your OEM gauges or mix and match up to two colors. Fits all N54/N55 Engines.This Part Fits:

Too narrow at the toes, even for narrow feet

Too narrow at the toe. I have narrow feet, but I could feel my toes being squished as soon as I stood up in these.. Bummer.

so cute
Size: 7, Color: Brown Patent
very cute shoes i love them, the quality is great these are my first pairs of Steve Maddens and they did not disappoint. i wear size 7 but could’ve gone maybe a half size up if it was available, they run a little smaller but maybe i jus have huge feet lol, the color is so cute dark brown matches my purse. i haven’t wore them out yet so im not sure about comfort yet but not all heels are comfortable so who knows, pretty hurts !!!

so uncomfortable
Size: 9, Color: Champagne
These shoes are cute but UNCOMFORTABLE. The toe thong makes them impossible to wear. I wore them for 5 minutes just trying them on and my feet hurt as I’m writing this. Couldn’t recommend less. Plus, the holes that the strap fits through aren’t lined up properly and are difficult to poke through. Felt like I got the made in china version.
