Cold Air Intake?

    Has anyone installed the Mountune cold air intake from FSWerks? Are there any others available besides the unit FSWerks has under development? I'm curious about the installation of the Mountune unit with the secondary air supply. The pic on the website shows a partial install but not the completed unit.

    It looks stock, all it does is add a tube for more cold air below the stock airbox.

    I have a question about the Mountune intake also. Does it require CARB certification since nothing is modified past the MAF?

    That tube is directed to below the car.
    This way it draws cooler air then from inside of the engine compartment.
    It works very well however you will not hear any additional intake noises.

    I do have it installed on my car.

    The stock system doesn't draw from inside the engine compartment. It draws from in front of the radiator (next to it). It's hard to see because it has a splash shield in front of the opening.

    I am aware of this.
    As I said, I have one.

    I was referring to most other CAIs that draw from the engine compartment.

    The Mountune CAI keeps the OEM snorkel as well.

    It helps if you use a lift during the installation. As Dave said, it does not increase the noise level but does draw cooler air from a secondary tube near the left fog light.

    Actually I installed mine with just the car jacked up laying on my back but a lift would always be better.
    Remember that there are only two professions where people get paid to lay on their backs; mechanics and hookers.
    I also ended the tube on mine in the center of the car.
    With a large zip tie, I tied it to the intercooler hose on the bottom.
    I thought it would get a better flow of cool air in that location.

    If the stock intake is a already a "CAI", what's the benefit of the Mountune unit?

    The only thing I can figure would be higher volume of cool air.

    Dave,
    I already have the Cobb AP and I'm kinda on the fence on getting the short shift kit or the Mountune intake next. Since you have all of them, what would you do next if you were me?

    The Mountune kit is a K&N filter, an air box with a hole in the bottom and a flexible duct, how hard would that be to reproduce?

    The short shifter seems like the thing to do.

    I installed the short shifter in mine before I had 100 miles on it!:)

    The short shifter is great and feels good, it has nothing to do with the tune so this should be no issue.
    If you want it, get it.

    I have chosen the Mountune parts for a number of reasons.
    They have been working closely with Ford for a number of years.
    They have great engineering backing with Roush.
    I do believe that they WILL work out the details with Ford and preserve all OEM warranties on the US cars as they have in the UK.

    The air box does not change the mas air flow meter or sensor therefore it WILL pass a California Smog Check.
    I like that it does draw air from outside the engine compartment and there is no additional noise.

    I like the Mountune intercooler because in MY OPINION it will recover from heat soak faster.

    I too have the Cobb AP and am very happy with the performance so far,
    I am sure that soon Tune Maps will be available that bring all of these into play.

    What you do with your car and money is of course, your choice, these are only MY OPINIONS,

    Hmm, 300 bucks for an extra cold air inlet? I think I'm going to hold off on this for a bit. Also are there any dyno numbers available for the Mountune intercooler? It would be interesting to see if the Cobb AP maps would help with the Mountune cold air intake and/or the intercooler.

    Each car responds differently to mods. It really depends on how good or bad the OE filter housing is.

    Take for instance the 2.3L duratec mk1 focus. They were seeing 13+HP from an intake as the original box was so restrictive. Some cars will fair better than others.

    Likely the OE Fiesta ST one is good enough from the factory and thats why we havent seen a rush of options or dyno #s from the manufacturers.

    That was a fun video. I was ready to say they hadn't considered true driving ambient conditions, but their Frankenstein setup more or less did.

    Only oil preference threads have more religion than intakes! I'm a fan of the CAI, and I think that real world testing proves it (but I also think the FiST air box is a very good design).

    One last point is that tubing material, length, and use of a venturi setup can make a difference. Back in the days of our SR20DE/T tuning, we stumbled on beneficial harmonic resonance. It sounded great, and made power you could measure!

    I would like to see a comparison between the OEM and a Mountune CAI.

    By keeping all of the OEM air inlets as well as keeping the OEM heat shielding and letting in more air from a cool source.
    I believe that the Mountune really is the best of both worlds.
