Magnus V5 Cast Aluminum Intake Manifold for Evolution IV to IX



History & Development

Over 20 years ago, Magnus Motorsports released its first Sheet Metal Intake Manifold into the market place and it quickly became the standard within the Mitsubishi Racing community. 10 years in we released the next big thing the Magnus Motorsports V5 Cast Aluminum EVO Intake Manifold. After two years of engineering and design the result had payed off with its performance results.

We designed this one from a fresh sheet of paper. Out of over a dozen prototypes, endless testing and perfecting, the Magnus Cast Intake Manifold was born. We applied our years of experience from crafting thousands of sheet metal intakes and once again have raised the bar for power and quick response. By applying a unique design and a massive 5L plenum, this cast manifold means big power and big power sooner!

The Design & The Results

Cast in A356 Aluminum with a wall thickness of 3/16″; the Plenum shape features a varying contoured tapered profile at a volume of 5 liters. The runners themselves are completely revolutionary in their design; featuring an integrated velocity stack that gradually transitions into the head port profile. It was designed entirely against the shape of the original cylinder head port, taking advantage of the 10° port entry of the EVO head and maintaining uninterrupted laminar flow. The Magnus Cast Intake Manifold will work with throttle bodies from stock right up to 100mm and have seen consistent gains from 30 AWHP to 52 AWHP with varying setups. Transient boost response is exceptional and it can bolt together in a stock location if required while still being able to be used on a full blown race application.
