Jackal/Tweetler Ported Intake Manifold

We've teamed up with Jackal Motorsports on their ported intake manifold program. A ported intake manifold with our Flapper Kit gives these motors an excellent boost in power throughout the entire rpm range. This matched with the 90mm Throttle Body is a power couple (compare to Cory and Topanga, Season 7). 

These intakes are required for Jackal Motorsports Stage 2 software, gains are roughly 60-70hp over stock. This, keeping in mind that HP gains are variable and influenced by multiple factors.


  • Custom porting of intake manifold and throttle body elbow precisely matched
  • Tweetler Performance Flapper Kit installation (FOR FREE)
  • Heat tape & Reusable gaskets (all you'll need)
  • (Optional) Finishing options: Spray or Powder Coat

Add durability and appeal of your intake:

The porting process thins the metal from an already thin intake manifold cover. While offering an economical "no finish" option, we highly suggest powder coating your manifold, which is both impressive aesthetically and adds heightened durability. By opting out, you elect to be sent an intake in the condition it was received at our facility. 

Powder Coating Before & After 
Spray Painting

Alternatively, we offer a spray painting service that also adds to the aesthetic appeal. We offer this in black, grey, gun metal, or silver and is treated with multiple coats. 

Intake Manifold Core Deposit Program

The B6/B7 intake manifold is becoming increasingly difficult to secure stock that meets the porting service volume. As of the release of this product, the cost for used, un-ported intake manifolds can run well over $1,000, if you can find one. Additionally, as many of our customers use their vehicle daily, removing and sending their own is not a viable option. Tweetler Performance keeps a small stock of manifolds ready for porting, allowing us to deliver product faster to you, at lower cost, and in a sustainable way for the shop. A win-win. 

  • Option 1: I'll send my intake manifold (6-8 weeks)

  • Option 2: I'll return my intake manifold after receiving

    • You deposit $500 today, get your ported manifold, then return your vehicle's manifold within 60 days for a full $500 return. 

    • Returns outside of the 60 day window will result in a reduced refund of $150. 

If you're unsure if your manifold meets the standards, or you don't have one to return please call, text or email us to discuss solutions.
