    This sounds promising and good for you in the fuel economy section!
    I was wondering if you can write up an instructions for a DIY (or PM me for more info).
    I am interested in testing this on my 2.5L. Would it be different since I have a SRI?

    I drive a 2.5L automatic. I use the Road Trip app on my phone and find I have been averaging 8.3 l/100km. According to the app, I should be able to get 720 km. going from full to fumes. I drive 60% highway, and don't go more than 10 km/hr above the limit. When I am on the last bar on my gauge I have usually gone about 550 km.

    Has anyone tried Eco Fuel Saver additive? Heavily advertized during Stanley Cup. Probably bogus but wondering if any actual experience here.

    Go to a site such as imgur or imsgeshack. Upload your pictures there and then post the direct image link here. You can also use Flickr or picasa if you have a yahoo or google account, respectively.

    So let's see of this works. I think the air intake setup is similar for the 2L and the 2.5 L engines.

    Above foto shows air dams to force air up into Mazda built-in "S" air scoops to air intake to breathe better as speed increases. The right side (from driver's view) one goes directly to intake. The left hand side goes up to LHS grill then across under the hood to the RHS grill/grating to feed the air intake. I cut out the air dams like a wide upside down tea cup to hold them in place from a windshield washer jug.

    <table style="width:auto;"><tr><td><a href="https://picasaweb.google.com/lh/photo/P4mfHGUPjqcpsYSy0t2c5ZTMtfySaJJp2PbdrK3xtd0?feat=e mbedwebsite"><img src="https://lh3.googleusercontent.com/-Lyq58wCfr2M/UA39zr6HBAI/AAAAAAAAABA/UT3hmyitAuc/s144/DSCN0882.JPG" height="108" width="144" /></a></td></tr><tr><td style="font-family:arial,sans-serif; font-size:11px; text-align:right">From <a href="https://picasaweb.google.com/117185088934875878522/Mazda3?authuser=0&authkey=Gv1sRgCL6E77aQ_YS2xQE&fe at=embedwebsite">Mazda 3</a></td></tr></table>


    The second foto shows the insulated air intake duct to shield it from heat from the engine, radiator and rad hoses above it. The air intake comes out in parts with some elbow grease. You can get a roll of 12" wide foam duct insulation with aluminum foil on one side and adhesive on the other from Lowes, or get 1 -1/2" foam pipe insulation. Cut it to cover the duct sections as best as possible and reinstall it. Afterwards, Add 1 to 2 layers of aluminum foil over the pipe insulation to reflect the heat all around.

    This does what K&N Filters do for $200 but it takes cool air from outside rather than hot air inside the engine bay. I am getting the rated 5.9L/100km hwy for the GX in hot 401 top and go commuting. It works good for about $30 and some elbow grease! Good luck!

    with regards to photos and picasa, you need to go to actions, album properties and edit visibility to 'anyone with link'. as for posting actual image url, just right click picture and copy image location.

    It's a far cry from the 9.4L/100km that I started out with, but I've been getting better mileage consistently, with the exception of my previous tank. City driving is an absolute killer for my 3, despite my good driving habits.

    Not planning to be there. ask any questions or PM me. It is fairly easy to do, just takes some time using basic materials. It took a couple tries to get it where it is now but any decent attempt will show some gas savings improvement. the Air dams are easy and may give instant improvement as the faster you drive the more air it forces which doesn't happen as much without them. My first try I got down to about 6.3-6.5 L/100km. I improved it- better insulation plus alum foil, better and 2nd air dams and I am getting 5.9-6.2 L/100k in 401 commuting and may be better in more hiway driving conditions. I also anticipate and coast maybe 10-15% of the time also.

    I did another mod to keep the cabin air intake a lot cooler from exhaust heat which helps a lot now that it is hot and I don't have to use AC hardly at all which saves a lot of gas also! Let me know how to post the pictures in the blog as I tried but couldnt and you did (where do I copy image location, in Picasa?), and I can post for this mod.

    How can I complain about fuel economy? I have been driving trucks for decades... with this I get 35 mpg and I don't baby it. One time I did, I kept it under 65mph on the open highway and I was getting 40 mpg

    I'm balancing out at 8.9L, which isn't great

    Any point in adding a cold air intake on an automatic?

    you can add it. but it wont make the fuel econ better, might not change or make it worse. im running about 9L avg right now up to mid 8s - 10.5l per 100km from my 5.8-7.5l per 100km i was getting in the summer. cant wait for some warmer temps
