Skunk2 Racing is proud to fill a unique need in the next generation of high-performance intake manifolds for swapped vehicles using the K20A/ K20A2/ K20Z1/ K24A1 engines or cylinder heads!

The much anticipated rear wheel drive Ultra Race Intake Manifold is the result of years worth of R&D and building upon the performance legacy of our Pro Series Intake Manifold. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The result is a design that is less restrictive, yielding both torque and power gains well over many of the competitors.

  • Modular 3pc. Design w/ Removable Plenum
  • 3.5L Plenum Volume**
  • 90mm Throttle Body Flange - Std. 5.0L Ford Pattern
  • 6.0” Tapered Hi-Velocity Runners
  • Raised 87mm Velocity Stacks
  • Generously Cast Runner Walls for Porting
  • Provisions Secondary Fuel Rail & Injectors
  • 4 x 1/8” NPT, 3 x 1/4” NPT, and 1 x 3/8" NPT Accessory Ports
  • Hi-Grade Mounting Hardware
  • Thermal Gasket Included

The K Series Ultra "Street" Manifold uses the EARLY PRB/ PRC style cylinder head and throttle body mounting flange pattern but can be installed on the LATE RBC/ RBB style cylinder heads through the use of an aftermarket Water Bypass Adapter and associated throttle body or throttle body adapter.

    I only use these pillows now
    Size: King (U.S. Standard), Number of Items: 2
    We’ll see if they keep their shape so far they have. They cradle my head well and I don’t wake up with neck pain anymore like I used to with my other pillows. Even my JC Penny feather down pillows lost shape so I switched to these and they are perfect. Extra large is great for me as I tend to roll around when I sleep. Perfect for back and side sleepers like me.

    Worth the money
    Size: Queen (U.S. Standard), Number of Items: 2
    So these pillows are for sure hotel pillows, great filling quality, support(not so much), no odor, they are worth the money, soft but just not the support I was looking for. Nice fluffy, hotel pillows

    The best!!!!! Don’t let the price fool you.
    Size: King (U.S. Standard), Number of Items: 2
    I don’t know how much money I’ve spent over the years trying to find the perfect pillow. I ordered these to use only as decor on my bed with some fancy pillow shams I had ordered and guess what- they’re my very favorite pillows I’ve ever gotten for sleeping. How in the world is that possible? So I switched my expensive pillow to my fancy sham and sleep on this every night. Buy it right now!

    Impressive Set of 4 King Pillows – Comfort Meets Quality
    Color: Black, Size: King (Pack of 4), Color: Black, Size: King (Pack of 4)
    Impressive Set of 4 King Pillows – Comfort Meets Quality I recently upgraded to this 4-pack of king-size pillows (20 x 36 inches), and they’ve been a fantastic addition to the bedroom. Certified by Oeko-Tex, they’re suitable for all sleep positions—whether you’re a side sleeper like me or prefer your back or stomach. The feel strikes a perfect balance between soft and supportive. The microfiber filling cushions your head and neck without going flat, so I wake up without the usual stiffness. They bounce back quickly after use and keep their shape well—just give them a quick fluff when needed, and they’re good to go. They do need about a day to fully expand once unboxed, but that’s expected. The design also deserves a mention. The subtle stripe pattern gives the pillows a clean, upscale look—definitely not your average basic pillow. They’d make a solid gift, too. Cleaning is easy: toss them in the washer on a gentle cycle with cold water, then either air dry or tumble on low. No hassle. If you’re looking for a dependable set of king-size pillows that feel great and look sharp, these are worth it. I also took a picture of it next to a standard pillow so that you could see the difference in the size from King to standard. Hope that helps, overall definitely buy these pillows if you are hesitant there is no need to be, these pillows are perfect in my opinion
