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

For certain applications, higher than normal oil pressure is required. Typically, the oil pan must be removed to change the pressure spring on an oil pump. The Holley oil system allows direct access to the spring through the access port on the bottom front of the pan. Holley's high-pressure spring for Ford 7.3L Godzilla engines with their oil pump and pan can be purchased and installed to increase oil pressure by approximately 10 psi at higher rpms. To change the spring, remove the port plug, spring, and plunger. In some cases, the plunger may stay in the port. Make sure when reassembling the plunger is on top of the spring and oriented correctly.

Holley offers LS swap 4WD truck off-road oil pan baffles for a variety of trucks, including many Chevy and GMC models from the 1970s and '80s. They take Holley's popular cast aluminum oil pans (P/N 302-4 and 302-4BK) designed to swap LS engines into K10s and other trucks to a whole new level. Vehicles that endure prolonged sessions of climbing, crawling, braking, turning, and accelerating need extra protection from oil starvation. That's where these baffle kits come in. They improve upon the baffle included with those pans, maintain proper oil level at the oil pump pick-up during vehicle elevation and grade changes, accelerations, both lateral and linear, and braking. This prevents loss of engine oil pressure during off-road excursions as well as during hard acceleration. Each baffle is fabricated from sheet aluminum joined by TIG-welded joints. Directionally positioned one-way trap doors allow oil flow toward the oil pump pick-up but not away. These direct bolt-in baffles are designed to be used in the Holley P/N 302-4 and 302-4BK LS Swap oil pan with the standard pickup, and are a drop-in replacement for the standard tray baffle. They're great for street, race, and off-road applications.
