Skunk2's Pro Series Intake Manifold for Honda's K-series features a larger plenum and shorter, over sized runners when compared to the RBC, and is cast with thicker wall material, leaving room for further porting for high-horsepower applications. Instead of producing a manifold with a significantly over sized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series manifold was designed for the street enthusiast who want more power but doesn't want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

Pro Series Intake Manifolds offer horsepower and torque gains greater than the popular RBC manifold but without compromising mid-range power output. The design incorporates runners that are similar in length to the RBC's but with larger bores, a special tapered design, as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined and hand-finished to best match the cylinder head's ports. Skunk2's Pro Series intake manifold's shape and design also increases wave scavenging effects at the engine's ideal operating range, which allow for a broad increase in usable power.

Dress look, without paying, big dollars!
Size: XX-Large, Color: Khaki
Well worth the $. With a sweater, perfectly fine for winter wear. Without a sweater? Perfect for fall Nice look You’ll need to have it ironed, in that it comes in a very small plastic. Minor ironing! A good buy!!

Very nice jacket/coat for the price
Size: X-Large, Color: Black
This was purchased to wear with a tuxedo for northern winter wear. The size XL is what he normally wears. It fit well over a tux shirt, vest and jacket. The length is perfect for a man; it covers the tux but does not get tangled in knees. It is lined in a satiny fabric. The wool type material is a bit rough, not soft, but it does the job. The black is rich looking and provides warmth for really cold weather. This jacket can easily be worn for casual wear. Should only be dry cleaned, but doubt it will ever really need to be cleaned.

Actually violet color and looks nothing like picture
Size: Large, Color: Red
Bait-n-switch. What arrives looks nothing like the photo. Its purple/pink and a misshapen ladies coat. Really low quality. And why they make them 90% polyester is crazy - just waiting to explode in flames!

Better than expected
Size: Large, Color: Black
Nice weight and kept me warm in 20 degree weather. I recommend adding a scarf for your neck line but this coat gives a nice clean but dramatic look.
