The 2.0T EA888.4 found in the MQB EVO / MK8 platform has possibly the most underwhelming engine cover to grace the 2.0T since its inception generations back. Some vehicles even came with no cover at all due to the fact the flimsy and floppy factory cover could pop off and catch on fire. APR fixed this with a new ridged carbon fiber design that's drop dead gorgeous. Available in Gloss Carbon Fiber Twill, and Exotic Gloss Forged Carbon Fiber, the new covers are sure to turn heads. They match the overall shape and theme of the factory cover, but ooze aesthetic appeal, thanks to the carbon fiber materials, red and black accents, and of course, the world-renowned APR logo plate. The engine covers look right at home in an otherwise stock engine bay, but shine when paired with an APR intake system and matching intake cover. Simply plug and play, no tools necessary! Of course, it doesn't affect emissions, and some on the internet have even suggested the covers may add horsepower, at least more than stickers do Additional features: * Significantly enhances the appearance of the engine bay * Reduces weight by 42 percent over stock (MK8 Version) * Enhances vehicle performance with weight reduction * Reduces weight over the front axles * Optimizes weight distribution * Emissions compliant

Ford 4.6L/5.4L modular 3-valve engines found in 2005 and newer Mustangs are all the rage. So the question on everyone's mind becomes, "How can I further improve the performance of these powerful engines?" COMP Cams XFI VSR Modular 3V (Valve Springs Required) Camshafts deliver a great power improvement over stock levels. These cams are the next step up from the COMP Cams NSR (No Springs Required) Cams and represent a major upgrade in power production. When compared to the NSR, stock valve spring compatible cam series, the VSR cams offer a substantial power gain in the higher rpm ranges. To achieve this, a high-lift design that requires a COMP Cams Beehive Valve Spring upgrade was created to maximize power within the limits of the OEM unmodified cam phasers. These new VSR camshafts are available for both naturally aspirated and supercharged engines, with two levels available in each series; one designed for maximizing mid-range power and torque, while the other maximizes top end horsepower. The performance secret behind these camshafts is in the extensive dyno testing that allowed them to determine precise cam timing events. Combining these optimized timing events with a high-lift lobe design offers substantial improvements in both power and throttle response. Designed to work flawlessly with the factory VCT, which is programmed to retard the cam timing above 4500 rpm, the new COMP Cams XFI VSR Ford 4.6L/5.4L Modular 3V Cams optimize both mid and high rpm performance.

The COMP Cams XFI SPR Ford 4.6L/5.4L modular 3V (Springs & Phaser Mods Required) camshafts are the best way to achieve the most power and torque increases possible with the popular Ford Modular 3V engine. These designs are the next step up from the COMP Cams VSR (Valve Springs Required) cams. When compared to the VSR cams, the SPR cams offer additional mid-rpm power increases as well as substantial power gains in the higher rpm ranges. In addition to increases in horsepower, you can also expect another 800-1000 rpm of useable engine speed and an awesome sounding idle lope to match. To achieve this extra level of performance, lobe profiles and timing events were specifically designed to work with the factory variable cam timing (VCT) system cam phasers for all 2005 and newer Ford Modular 3V engines. These cam phasers were modified with the required COMP Cams Cam Phaser Limiter kit to restrict their movement to no more than 20 degrees. This simple modification gains additional piston to valve clearance, allowing for much larger cam designs. This results in cams that not only maintain low and mid-range power, but have incredible high rpm performance as well, all while maintaining the benefits of cam phasing. As noted by the COMP Cams engineering staff during extensive dyno testing, these camshafts provided the biggest power and torque improvements of any cam series they've ever tested in the Ford Modular 3V engine.
