The Magnus Intake Manifold has become the standard in the Mitsubishi racing community. With a track record over 10 years of proven race use under its belt, the Magnus intake manifold has had many different iterations, a testament to our quest for constant improvement. Magnus has taken our design philosophies and applied them to the Subaru and Honda aftermarket, with staggering success.

Power and quick response has always been the main stay of the original Magnus Intake Manifold. Quickly it was adopted for not only street use, but drag, autocross and road race use as well.

Magnus Motorsports - Intake Features


Our exclusive tapered Plenum shape intake manifold has been the benchmark that imitators have always shot for. It has been the must have item for the enthusiast looking for top end power without sacrificing bottom end performance. Years of testing has netted us the optimum design which does not sacrifice torque or spool up, while still offering superior breathing in the higher RPM’s.

All Magnus Sheetmetal Intakes come with a limited LIFETIME WARRANTY. Please contact us for details.

We were the first to offer all of these features and are still the very best, the quality and fit and finish are second to none. Our on staff welders have a minimum of ten year TIG experience with aluminum; to them it is an art. Every weld is consistently challenged to be better than the last.

  • State of the art super high frequency welding equipment is used to accurately and consistently give artistically perfect beads on every Intake manifold.
     
  • Beautifully machined 180 degree velocity stacks are incorporated into all our intake manifolds.

  • Perfectly shaped runners blend into the port of our CNC machined Flanges.
     
  • Manifolds plenums are TIG welded inside and outside to improve strength.
     
  • The ports are hand blended to further improve airflow, and the base flange is accurately CNC flycut to ensure a perfect seal.
     
  • All intake manifolds are mirror polished at no extra charge.
     
  • Each intake manifold is hand crafted for the ultimate in Finish, quality, and power. You won’t find a better looking finished piece on the market.
     
  • Magnus also offers High flow Fuel rails for all of our intake manifold applications.
     
  • Heat barrier gaskets are also available, to further help reduce heat soak into the intake manifold, these are not only a performance increase, but also reusable.

We offer direct-nitrous plumbing and nitrous installation on, Nitrous bungs, Larger throttle body flanges, additional bosses, additional fuel rails for staged injection. Because all fabrication is done in house, Magnus can custom tailor your manifold to your needs. Special one-off intake manifolds can be created by request, and for different vehicles.

MAGNUS MOTORSPORTS INTAKE MANIFOLD WARRANTY POLICY

While we pride ourselves on having one of the lowest rates of failures in the replacement manifold industry, we do occasionally have a part that fails in use. When this is brought to our attention, our policy is simple. IF ANY MAGNUS MANIFOLD EVER FAILS BECAUSE OF A DEFECT IN MATERIAL OR WORKMANSHIP, SEND IT BACK TO US AND WE WILL FIX IT AT NO CHARGE WHATSOEVER TO YOU. THAT'S RIGHT – LIFETIME WARRANTY AGAINST ANY FAILURE THAT IS OUR FAULT – AND NOT JUST TO THE ORIGINAL OWNER – THIS IS A LIFETIME WARRANTY OF THE MANIFOLD ITSELF. But we go even farther. If you have a failure that was NOT due to a defect in materials or workmanship – like the common nitrous, meth, or alcohol backfire events, if you send the manifold back to us for inspection and testing, we'll sell you a brand new replacement manifold at a significant discount, even if it was damaged through absolutely no fault of our own.
