Billet Specialties LS Modular valve covers offer a unique solution for hiding your LS coil packs. The valve covers are a 2-piece design that bolts together to make one cover. The base features mounts for the ignition coils, a hidden oil fill, and a 1/4 in. NPT provision for breathers or PCV in the rear of the cover. The top piece bolts to the base with polished ARP fasteners, perfectly covering the coil packs for a seamless look. Holes are provided in the side of the covers for the spark plug wires. These covers are machined from a solid piece of aluminum and are available in a variety of finishes and top styles (ribbed, logos, etc.). LS Modular valve covers are ignition coil-specific to accommodate multiple styles of coil packs. Order the model designed for fitment with your vehicle and engine application.

COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.

Inspired by Dart's championship winning Pro Stock designs, Dart Pro 1 aluminum cylinder heads cover a wide range of applications from street cars and trucks to all-out racing. Heads designed for street performance and mild bracket racing offer excellent mid-range torque and power, and are excellent for heavier vehicles. Competition heads are ideal for maximum effort naturally aspirated, big boost forced induction, or nitrous applications. Dart Marine Pro 1 cylinder heads feature an exclusive chromate surface finish to inhibit corrosion and extend the life of the head. They are also fitted with Inconel exhaust valves to withstand the extended running time and temperatures typical of marine usage. Dart's as-cast ports flow more than many ported designs at a much more affordable price. But they also offer fully CNC-machined heads with every intake port, exhaust runner, valve bowl, and combustion chamber shaped by their 5-axis, computer controlled machining centers to produce compound curves and complex shapes that no human could duplicate with a hand grinder. Available bare or fully assembled, long-wearing bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard on most heads. Assemblies typically include stainless steel valves, premium springs, locks, retainers, guide plates, and seals. Many Pro 1 heads include race-proven features such as improved spark plug location, extra-long intake valves, raised exhaust ports, and fast burn chambers. They are offered an extensive variety of valve angles, intake port volumes and shapes, exhaust port locations, valve sizes, and chamber volumes.

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
