Turbosmart BOV Kompact Dual Port (Louder) - Focus ST Fits All Years: Focus ST (2.0L) Like all Turbosmart blow off valves, the new Kompact Shorties have been machined in-house, from solid billet aluminium. Keeping the process in-house, ensures only the best quality, and none of the cracking or leaking that plague the factory plastic valves. Like their predecessors, they’ve been engineered with a light-weight, brass/aluminium, two-piece piston. Carefully engineered springs make these the most responsive valves of their kind. The Kompact Shortie fits a huge range of turbos, and their tiny dimensions make them a breeze to fit. To make things even easier, Shorties are supplied with both a swivel “banjo” nipple and a straight nipple, meaning you can tailor the valve to better suit your application. Larger o-rings have been fitted in the base to aid ease of installation – another modification made after talking to our authorized dealers and installers. Small design means Shortie is easy to install. All billet construction, and well-designed internals mean it will hold as much boost as you want to throw at it, for as long as you need it to. The Plumb Back version is as quiet as a factory valve, or if you’re looking to make a little noise, the Dual Port version’s superior flow characteristics will safely provide that BOV sound you’re looking for. The new twin fixed ports flow more than ever before. You just can’t lose with Turbosmart’s Shortie. Learn More

When Turbosmart began making performance products back in 1997, a great amount of effort was put into the design and manufacturing process to ensure our products created a new standard. More hand-crafted than mass-produced, Turbosmart products quickly gained acceptance within the performance community for their quality and reliability. Coupled with extraordinary service and after-sales support, Turbosmart quickly became one of the most sought-after names in the industry. Not much has changed since then. Although our product line and the company itself have grown considerably, the products are still designed and manufactured in our factory in Sydney, Australia, using the same tried and proven formula of innovative design, strict quality control, and rigorous testing. We have invested in our research facility manufacturing equipment and staff training to ensure our products continue to perform up to and beyond your expectations. At Turbosmart, we do not believe in cutting corners and half-measures. We do not accept anything short of perfection - and neither should you. Learn More

GFB DVX Fits Ford Focus ST Fits All Years: Focus ST (2.0L) GFB DV+ Diverter valve (Part number T9301) is a direct bolt on factory valve replacement. Designed to replace the weak plastic Bosch diverter valves commonly found on European applications like Audi, Ford and VW, but with the GFB TMS advantage. The TMS range from GFB is designed specifically for the purpose of turbo lag reduction, and improving throttle response. Tests show TMS features can return engine to peak boost up to 30% faster than a factory diverter valve when shifting gears. Unlike other aftermarket Bosch replacement valves on the market, the DV+ will hold as much boost as you can throw at it WITHOUT the need to adjust the spring pre-load or purchase different springs. This is because the pressure-balancing design of the DV+ means that under wide open throttle conditions there is equal boost pressure on both sides of the piston, so it will stay shut under boost REGARDLESS of the spring setting or the boost pressure.

Open up the flow of the charged air in your 2013+ Ford Focus ST with the Mishimoto Performance Intercooler Piping Kit. The piping equipped on the 2.0L EcoBoost engine from the factory is riddled with bends, restrictive piping diameters, and degradation-prone materials, all of which slow the air to and from your intercooler putting a strain on the FOST?s performance. We here at Mishimoto strive to free the flow of the charged air in your sporty Focus. To start we removed the turbo muffler from the design of the hot-side stock piping, and reduced the amount of bends giving the airflow a more direct flow from the turbo to the intercooler. On top of the reduction of bends, we increased the inner diameter of the piping to 2.5 inches of high-grade aluminum, allowing for a 14% increase in volume and 26% greater flow over the stock equipment. The stock rubber connections have also been replaced with sturdy silicone couplers to ensure solid connection between piping and intercooler. The improvements don?t stop with the hot-side piping. The cold-side piping received an overhaul as well, replacing the degradation-prone rubber construction with 5 layers of durable silicone complete with heat-resistant fibers, ensuring that the cold-side airflow stays cool. For added support, the single section of piping is reinforced with steel wire ensuring that it keeps its shape under heavy load. Speaking of shape, the Mishimoto Performance Cold-Side Intercooler Pipe features an elliptical shape to accommodate the increased size of the Mishimoto Performance Radiator.The result of adding the Mishimoto full Performance Intercooler and Piping kit to your 2013+ Focus ST in conjunction with the Mishimoto Performance intake is a 21% increase in flow of the charged air through the system, and an additional 8hp and 10ft/lb of torque boost on top of intake and intercooler gains on the stock tune.

It's time to make your cool off your hot-hatch with the Mishimoto Performance Intercooler Kit for the 2013+ Ford Focus ST. Ford released their 2.0T EcoBoost powered Focus boasting the perfect combination of performance and practicality, however the intercooling system left something to be desired. While the piping did feature sections of aluminum, the restrictive diameter, not to mention the turbo muffler put a damper on the Focus ST?s performance potential. We?ve replaced the hot-side pipe with mandrel-bent aluminum, both ditching the muffler and also opening up the diameter to allow a 26% better flow through the hot-side. All of the degradation-prone rubber has also been swapped for wire-reinforced silicone ensuring a long lasting connection on the hot-side, but also a soother flow through the cold-side pipe. Together the Focus ST Intercooler Pipe kit grants a 21% increase in flow to and from the intercooler. The piping isn?t the only part of this kit that increases flow, the bar-and-plate construction opens up air channels within the core allowing for the charged air to pass through more freely than the stock intercooler core. This upgraded all aluminum construction also aids in heat dissipation, warding off the dreaded heat-soak under demanding driving conditions, and delivering properly cooled air through the ST?s intake manifold. The Focus ST Performance Intercooler Kit will also add 8 HP and 10 TQ to your power band and has a maximum horsepower rating of 550HP. The Mishimoto Performance Intercooler Kit for your 2013+ is available in silver, black, or gold, with an option of wrinkle black or polished piping. As always, this intercooler kit is covered under the Mishimoto Lifetime Warranty. Learn More
