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
  • Fits MOST Popular Chassis Configurations - Not Just Race Cars - See Notes

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.

    Best chew toy we have ever purchased.
    Flavor Name: Classic, Size: Large
    My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with. It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end. All in all a fantastic toy!

    Happy Doggo
    Flavor Name: Beef, Size: Small
    He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

    Excellent product, highly recommend

    So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!

    Dogs love them
    Flavor Name: Beef, Size: Small
    My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!
