These Professional Products SFI Spec PowerForce Plus dampers provide more applications for a wider range of engines. All Professional Products PowerForce Plus dampers feature a bonding process, which adheres the elastomer to the i.d. of the inertia ring and the o.d. of the hub.

Mishimoto baffled oil catch cans are designed to separate oil particles from the PCV air that would normally have just been routed back to your intake. They feature custom grooves in the catch can's inlet that turbulates the air longer and ensures that all of the oil sinks to the bottom, leaving nothing but clean air to pass through the 40 micron bronze filter to the intake. An internal baffle keeps the collected oil from splashing around under race conditions. These catch cans are machined from 100 percent billet 6061 aluminum, and accept AN fittings at the inlet, outlet, and drain area—allowing for over 27 possible configurations. For maximum fitment options, the top cog mounting setup enables the cans to be mounted from multiple angles. To make maintenance easy, the drain plug can be removed to allow for AN return to the oil pan. Mishimoto baffled oil catch cans are washable, unlike many other cans that require you to replace your filtration system, and they're available in a variety of colors. Order the model recommended to fit your vehicle, engine, and/or transmission application.
