Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 8,000 rpm if you do not have the correct springs. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. COMP Cams valve springs are offered in single and dual styles to meet your cam requirements.

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.

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.
