6.1 HEMI Stage 2 Ported intake manifold

A 6.1L SRT8 HEMI ported intake manifold is a grate option if you’re looking to increase your horsepower but don’t want to upgrade to a 426 HEMI stroker just yet. Our ported intake manifolds are opened up to 90mm giving you the option to upgrade to a 90mm throttle body in the future. All of this work is done by Thitek performance, A2Speed’s partner for ported heads and intakes. Thitek is the creator of the GEN III HEMI’s first true 100% aftermarket heads. They are the premier head set up for the market today. When it comes to porting there is no one better than Thitek. Stage 2 ported intake manifolds feature a completely smoothed and polished interior, vs. just porting the runners and the throat. This helps increase overall airflow and reduces potential airflow disturbances, meaning overall airflow to your cylinder heads is increased.

  • About Us

  • How We Do It
  • Our Quality
A2Speed is an employee owned automotive performance parts company, specializing in the Gen III HEMI engine and the cars & trucks it powers. Just like you we are Hemi enthusiasts, and like you we are only interested in proven performance solutions. Good enough isn’t. People who invest in performance modifications want parts that last decades, not years. The effort is only valuable if the result is better than good enough, and frankly these days that’s hard to do.

A2Speed’s GEN III HEMI Background

Many of us at A2Speed have been working on the Gen III since its inception. As a team we are immersed in the Hemi world. We own, drive, modify, race and occasionally…break them. We use this experience to create SOLUTIONS, not just parts. Automotive engineering has advanced such that it is often difficult to improve on the work done by the OEMs. Difficult, not impossible. Utilizing advanced 3D modeling, CFD and stress simulations coupled with rapid prototyping, allow for the development of specialized parts that would be impractical at OEM volumes. Solutions validated with real world testing. Craftsmen level quality; and because we don’t have the layered overhead, our prices are often at or below the OEM price.

Advanced Aerospace Grade Machining

Production manufacturing is performed by partner companies that have proven track records for quality and timely deliveries. We look for certifications such as ISO-9001 and AS-9100 along with ITAR and GIDEP registrations. Several of the companies we work with regularly supply major aerospace firms and the DOD. Why use outside machining services? So that you get a better part at a better price. By utilizing only the machine cycles we need, and leveraging the superior skills and years of experience, A2Speed can give you exceptional quality at truly affordable prices.

Our company is guided by a set of core values and beliefs

  • We know that we are a community, not a “market”.
  • We recognize that we serve this community at the pleasure of its members.
  • We understand the passions, challenges and rewards that drive the enthusiast.
  • We believe that function drives form, improved performance improves appearance.
  • We know that one company can’t do it all, therefore we value partnerships.

How This Applies to Our Customers

  • We never settle for anything less than perfection.
  • All of our parts are put under intense testing before being released to you
  • You can feel secure because we use both our closest partners and our own cars to test A2Speed’s products
  • Finally we know that just having a great product isn’t enough, thus we strive to offer superior customer service, and the lowest prices. Giving you the best experience possible from start to finish.
