Summit Racing™ Split Lock Bolt Kits

Summit Racing™ split lock bolt kits put a new twist on the theory of mechanical locking fasteners. These innovative bolts use a locking set pin built into the bolt itself—and when tightened, the set pin expands the bolt threads against the thread wall. This, in turn, provides a locking system without having to use any additional wires, locking compounds, or lock washers. To remove the split lock bolts, simply loosen the set pin and back out the fastener. They are available in a variety of thread sizes, for engine applications from the 1950s and up.

APR Engine Covers

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
