I got a M2 (also known as Mostly Mazda) Aluminum Intake. The engineering of the intake was very well thoughtout. The intake is CNC cut and Tig welded. The fitment of the intake was good. I had to mangle it a little to get the bottom opening of the box, (where the airs get feed) to get it to fit. The unit is excellent in design and well built, but I am not sure if the opening on the bottom next to the radiator is big enough. It will be next to impossible to use this Intake system with a singel Turbo kit. The M2 (Mostly Mazda) Intake did make a big difference in performance and I feel is good for someone who wants to stay at a stage 3. I do want to explore my other options with Intake systems.
Other intakes that I am looking at are the SR Motorsports, Apex-I, Greddy, HKS, Blitz and Tri Point Engineering. I will be contacting them to see if they want their product reviewed.
