The Skunk2 Ultra-Race Series Billet Intake Manifold, for Honda K series engines is the ultimate manifold for high-horsepower street and race engines. Unlike the standard Ultra Manifold, the Billet Ultra was designed for 8-injectors mounted top-side with a single fuel rail.

All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD and on the dyno. The short tapered high-volume runners combined with a large plenum favors maximum top end power over lower end power and response. Skunk2 Ultra Manifolds also incorporate a modular plenum design where plenum volume can easily be increased using simple spacers, and runners that can easily ported for additional flow and volume.

After rigorous in-house and third-party benchmark dyno testing, Skunk2 has yet to test an intake manifold that can match the performance of the Skunk2 Ultra Race Manifold. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their needs.

The combination of the billet coolness-factor with limited production makes the Skunk2 Billet Ultra Race Manifold special offering.

*Does not fit K20C variants

The Skunk2 K-Series Ultra Street manifold is designed with an early style (PRB) intake manifold flange. Engines with the later style (RBC) flange will require the use of an aftermarket water bypass adapter.

    Comfortable, soft
    Size: Standard (2 Pillows + 2 Protectors), Style: Soft, Configuration: Pillows + Protectors
    I bought this set of pillows and they have exceeded my expectations. They are pleasantly soft and provide good support for sleeping. The size is standard and fits perfectly with regular pillowcases. I like that they maintain their shape after use and that they don't feel too hard or too soft. In addition, the material feels cool and of good quality. Overall, they are a very good option if you're looking for comfortable, functional pillows at an affordable price. I would definitely buy them again.

    These are always the best pillows to buy! Soft and comfortable. They are a great buy for the price. I wish the material was more organic but that’s okay they are still nice.

    Very comfortable and soft
    Size: Standard (2 Pillows + 2 Protectors), Style: Soft, Configuration: Pillows + Protectors, Size: Standard (2 Pillows + 2 Protectors), Style: Soft, Configuration: Pillows + Protectors
    They are exactly what I expected. Fluffy, comfortable, and the size is perfect. They arrived quickly and were well-packaged. For the price, I doubt you’ll find anything better; I sleep much better now, and they really help me relax. Honestly, I love them—I highly recommend them for a good night's rest.

    Soft, Fluffy & Decently Supportive
    Size: Standard (2 Pillows + 2 Protectors), Style: Soft, Configuration: Pillows + Protectors
    These pillows are wonderfully soft and fluffy, making them great to sleep on. They hold their shape well, especially if you get the version with a protective cover. Comfort is good, and they moderately stay supportive through the night. Overall, a great pillow pick that works exactly as expected.

    Too firm
    Size: Standard (2 Pillows + 2 Protectors), Style: Soft, Configuration: Pillows + Protectors
    Too firm. Seems like there is too much filling inside the pillow. You can’t fold it in half or burrow into it. Otherwise the quality is quite good.
