Skunk2 -10AN Valve Cover Vent Kit - K Series (K20 / K24)
Built a K-series and you're ready to plumb a real breather or catch can setup? This is how you do it clean. The Skunk2 -10AN valve cover vent kit gives your K20 or K24 two big -10AN ports right in the valve cover, so you can run -10AN lines straight to an external breather, oil separator, or catch can without hacking together fittings that don't fit. It's a straight bolt-on, two fittings thread right in, and your crankcase ventilation is sorted. If you're chasing more power and your engine's making more blow-by than the stock PCV setup wants to handle, this is the upgrade that keeps your crankcase pressure under control and your intake clean.
Why You Vent The Valve Cover On A Built K-Series
Here's what's going on inside your motor. The harder you push a K-series, especially once you're spinning it to high RPM or adding boost, the more pressure and oil mist builds up in the crankcase from blow-by past the rings. That pressure has to go somewhere, and if you leave it on a stock PCV system, a lot of that oily air gets pulled right back into your intake, gunking up your manifold and throttle body and costing you consistency. Venting the valve cover to an external breather or catch can gives that pressure a clean way out and keeps the oil out of your intake tract. This kit is the plumbing that makes it happen, two -10AN ORB to -10AN fittings that thread directly into your valve cover, sized big enough to actually flow the volume a serious build puts out.
Stainless Mesh Pre-Filters Keep Oil Out Of Your Breather
The kit comes with two stainless steel mesh filter inserts, one for each fitting, and they're doing real work. They sit in the fittings as pre-filters and catch oil mist on its way out, so less oil makes it into your breather system or catch can. That means you're not constantly emptying an oil-soaked catch can, you're burning less oil, and your whole ventilation setup stays cleaner and works better. It's a small detail that makes a real difference in how often you're out there dealing with the mess.
Made For The Skunk2 Magnesium Valve Cover
One important thing before you buy: this vent kit is built to thread into the Skunk2 Ultra Lightweight Magnesium Valve Cover for K series. That cover has the -10 ORB bungs these fittings screw into, so this kit and that valve cover are designed to work together as a pair. If you've already got the Skunk2 magnesium valve cover on your RSX, Civic Si, or other K-swapped build, this is the kit that finishes off your breather plumbing. If you don't have that cover yet, plan to grab it alongside this so you've got somewhere to thread these fittings.
Who This Is For
This is aimed at the K-series crowd running a real breather or catch can setup, high-RPM naturally aspirated builds, boosted K20s and K24s, and track cars that need to manage crankcase pressure properly. If you're plumbing an external oil separator or catch can with -10AN lines, this kit is the connection between your valve cover and that system. For a mostly stock daily, you probably don't need it, but for a built motor that's moving real air, this is how you ventilate it right.
