    I finally am getting to some upgrades for my zetec wagon. I just test fitted the Iceman tube and found out the stock MAF unit is only 3 3/4 inches OD and the TB is only 2 5/8 Iceman is 4 inch OD on the inlet and on 3inch OD on the outlet. So what did you guys do to match them up? I figure a reducing coupling on each end is in the works Maybe 4 x 3 1/2 and 3 x 2 1/2. Also, any suggestions on the IAS mounting... Just drill a hole to fit a gromet for the factory sensor?

    Thanks

    Thanks,
    Just making sure I am not missing something. I plan on insulating the intake also to help keep the intake temperature down in city traffic.

    sounds like you are planning to use the maf without the factory air filter housing. This is not the best plan of action as the factory airbox is better looking and is a true cold air setup. Also, if you are planning to do this then you will be better served not using the iceman. The iceman is one of the best because it is a direct bolt on for the factory airbox

    i also recommend not drilling a hole in the iceman. Most people dont drill it right, dont use the right fitting for it and it does not always look good once done this way. The better way to do this would be to upgrade the MAF to the 6-wire version. Doing this will eliminate the need for the additional sensor and simplify your wiring. If you do it this way get the wiring harness for the 6 wire and a couple inches of the connector for it. The connector for the 6 wire is the same color scheme as the 4 wire before the harness. It is just a matter of matching the colors and it works and will give you a cleaner, simpler install

    the coupler for the throttle body can use a 2.75. A 2.5 will also work but it is a real tight fit on the iceman

    I'm using the stock MAF housing and air filter housing with the Iceman intake tube. I cut the filter housing to open up the air filter inlet to 3 inch and attached a 3inch PVC pipe to bring the end back into the fender well to draw cool air. I've radiused the end of the 3 inch PVC pipe ( schedule 40) to help reduce the turbulence at the air inlet. Cutting the end of the air filter housing also got rid of the other resonator. I hope to have pictures in a week or so.

    Any other advantage to the later MAF housing other than the combined air temp sensor? Is it already 4inch at the coupling connection?
    I am starting to look at what the possibilities are for a bigger MAF and bigger TB. I've read that the MAF housing off a 96 mustang would work ( 70mm) , but the ECU would need to be tuned. It probably won't make much difference going bigger until I get a bigger exhaust on there ( trubenz 2 1/4). From what I've read from a focus ZETEC tuning book, a high flow cat makes a lot of difference, even though it seems like it really shouldn't at these relatively low power levels.
    Right now the engine will have/ has a pacesetter header ( emission legal), 25% underdrive pulley ( lighting is nearly all LED and the car is insulated/soundproofed so heater fan runs on lo in winter), and the Air Intake upgrades. I am also going to insulate the intake to help reduce heat soak during the summer and in city traffic.

    I agree with 4cylinder. Get the 6 wire MAF. It'll make life much easier. Inlet and outlet diameters are the same as the 4 wire.

    I would stick with the OEM MAF and TB. Adding a larger pipe diameter will certainly give it more CFM usability but that really depends on how much air the engine needs and the stock one seems to pull all the air the engine needs unless you're running a turbo at high compression.

    Not sure how much benefit you'll get from insulating the intake as the air going through it moves pretty quickly so not much time for it to heat up. More important is the source air temp. Wheel well is a good location for drawing fresh air and allows the stock setup to stay intact.

    High flow cat will make a marked difference, I know this because, at one point, the monolith in the stock cat I had got clogged up. I removed the cat and poked out the monolith and essentially cleared the cat as a straight pipe. Definite jump in torque and HP. After the stock exhaust manifold cracked I installed a stainless 4/2/1 header with straight pipe. This upped the torque and HP even more.

    Well I have had a chance to drive the car a couple hundred miles with the new Iceman intake and the opened up air filter housing. It has really upped mid range and upper end power. I had it out on a cold rainy day and jumped on the gas at around 50mph. I think I nearly broke the tires loose when the trans downshifted...between the intake upgrades and the cool damp air it was a little scary. The gains weren't unexpected, considering the stock filter housing opening is only 1 1/2 inches and now is 3 inches and the better intake tube too. This 1 1/2 inch is still much bigger than the intake to the 1.9 on my 93 wagon.... it was only 1 inch and opening that up while still retaining cold air intake really helped that engine. That engine would run out of power at about 2,800 rpm stock and opening the intake to the airbox allowed the engine to pull well up to about 4200 rpm. I've heard from a number of sources that just this mod to the 1.9 can make it pull stronger than the 2.0 SPI in the later wagons.

    It should be really interesting when I upgrade the exhaust from the stock 1 7/8 and standard muffler to the 2 1/4 inch trubenz with magnaflow. With the intake already opened, I be this will really help the high end
