Fluidampr Harmonic Dampers

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers can control all crankshaft vibration--not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.

Diamond Pistons Sport Compact Series Pistons

Diamond Pistons Sport Compact Series pistons are ideal for either the street or the drag strip. These forged aluminum pistons are significantly stronger than the factory pistons allowing your engine to handle that extra horsepower. Diamond Pistons Sport Compact Series pistons feature: * 3D milling on piston crowns for "ready to install" finish * Side gas ports for better ring seal * Moly skirt coating for friction-loss and skirt-wear protection * Oversized valve pockets for "larger than stock" valve sizes * Forged 2618 or 4032 aluminum alloy (where specified) * Premium 8620 or H-13 steel wrist pins (where specified)

APR 3.0 TFSI Supercharger Drive Kits

APR 3.0 TFSI supercharger drive and crank pulley upgrade kits have been designed to dramatically increase the rotational speed of the factory supercharger. When combined with APR's Ultra-Charger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance! The supercharger drive pulley decreases the diameter of the factory pulley from 63.25mm to 57.75mm, which in turn spins the supercharger 9.5 percent faster. This results in a healthy bump in horsepower and torque across the entire rpm range with the supercharger operating at a higher rate of speed. The pulley is CNC-machined from billet stainless steel, E-coated factory black for an OEM appearance and is press fitted to the factory supercharger unit. The supercharger crank pulley increases the diameter of the factory pulley from 162mm to 187mm, which in turn spins the supercharger 15.4 percent faster. This results in a larger bump in horsepower and torque across the entire rpm range, as the supercharger is spinning at an even higher rate of speed. The pulley is CNC-machined from light weight billet aluminum with weight saving pockets throughout and has an anodized black finish and includes new crank pulley bolts. It retains the factory harmonically balanced crank pulley and bolts on top of the existing unit. Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning faster than stock, which results in an even higher horsepower and torque gain across the entire rpm range. However, at the airflow levels achieved with a dual pulley setup, maximum power is severely restricted by the factory throttle body unit. APR's Ultra-Charger Throttle Body Upgrade is necessary to take full advantage of the dual pulley configuration and is available in platform specific variations for the B8/B8.5 A4/A4/S4/S5, Q5/SQ5 and C7 A6/A7.

APR Catch Cans

APR oil catch cans are able to increase performance. They trap excessive crankcase oil vapors and gunk, eliminate possible performance-robbing boost leaks, and will reduce airflow-restricting carbon buildup, octane-lowering oil vapors, and oil pooling within the intake tract. APR oil catch cans are simple modifications to install, drain in seconds with the flick of a knob, and recommended at all stages of performance.

Standard Motor PCV Valves

Standard Motor Products replacement PCV valves are emissions-control devices that route unburned crankcase blowby gases back into the intake manifold where they can be re-burned. By totally eliminating crankcase emissions, the constant recirculation of air through the crankcase helps to remove moisture, which would otherwise cause sludge to form. Standard Motor Products replacement PCV valves will extend the life of the oil and the engine.
