The engineers at Skunk2 Racing have worked tirelessly to develop the next generation of high performance intake manifolds and are proud to announce the release of the much anticipated Ultra Series Intake Manifold. Years of R&D have culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow.

Building upon the performance legacy of our Pro Series Intake Manifold, as well as using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy dis-assembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno and on-car testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors.

Ultra Series Intake Manifolds are made from high-grade 356 aluminum alloy for a strong and lightweight design, CNC-machined for a precise fit, and individually inspected for quality assurance. The large 90mm throttle body opening, 87mm velocity stacks, and hi-velocity intake runners with smooth transitions allow the Ultra Series Manifold to outflow the competition. Designed to be used with built, high-horsepower naturally aspirated or forced induction setups, the Skunk2 Ultra Series Intake Manifold helps provide a new level affordable high-end intake technology to the marketplace.

  • Ideal for turbocharged and naturally aspirated race engine build applications
  • 3.5L = high horsepower N/A & Forced Induction engine build applications up to 600hp
  • Skunk2 Ultra Series 90mm billet throttle body available separately

    Vehicle Applications

    The Ultra Series K-series intake manifold is race application and is NOT a direct fit for the 02-05 Civic Si or 02-06 RSX vehicles (both use PRB style heads). However, Skunk2 tells us the manifold will fit the following K20 or K24 swapped vehicles (using a PRB style head) along with the either of the following components:

     

    • Karcepts or  K-Tuned A/C & P/S Eliminator Kit (KP-UNV-385)
      OR
    • Electric water pump w/water block off plate (K-tuned kit# KWP-PKFJ-204)

      Will then fit these tested K-swapped vehicles:
    • 92-95 Civic
    • 96-00 Civic
    • 94-01 Integra

    Paid for new, received used.
    Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
    Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

    Decent Shoes with Misleading Description (Not Leather)
    Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
    I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.

    Perfect buy!
    Fit Type: Regular, Size: Large, Color: White
    This white denim jacket came today, and finally I bought the perfect jacket! It's actual denim, heavy but not too bulky. It fits perfectly, I bought a large, it's white not off white, and it is EXACTLY what I was looking for! I had to wait a week or two but it is definitely worth the wait! Beautiful jacket, well made and at a decent price! Thanks Amazon Essentials!

    Love denim and tired of cropped jackets?
    Fit Type: Oversized, Size: Large, Color: Medium Blue Vintage
    I like this a lot, it was what I was looking for as far as I'm so over everything you buy these days is cropped. Cropped styles are great, but are kind of getting old for some things in my opinion. The jacket is big as far as how it fits. I am 5'8" about 180 and I wish I would have got a medium, I got a large. The large is big and roomy enough that I could even wear ear a thick hoodie under it if I wanted to. However, the length is good as what I was looking for. The upper arms are large. However, this is a great quality denim jacket. Nice and thick, sturdy material (which I wanted). It's also at a great, competitive low price even if it's not on sale. Don't believe me, go ahead and search jean jackets. You'll see a ton, but I looked too and the quality did not look as good as this and plus the other jackets were a lot more for a lot less. If you're looking for a longer jean jacket, I highly recommend this. I'd say just think seriously about sizing down 1... even maybe 2 sizes. I would have gotten an XL before I read the other reviews. They recommended to size down, and after getting my jacket I could have sized down to a medium. I'm still happy with it and this is a jacket that is stitched well and will last a very long time. As always though, that's just my 2 cents. :)
