While you won't get higher boost simply from installing this intercooler, you will get lower intake temperatures. This will allow the Mazdaspeed's ECU to be a little more aggressive with timing and make a little more power. It will also be useful when you turn up the boost and start making more power - and more intake heat. The new intercooler core measures 15" x 8" x 3". The stock one (shown here for comparison) is 8.5" x 8.5" x 2.5" - the new one has twice as much the volume.
Easy installation using the stock Mazdaspeed piping. A short section (4" on the inlet, 2.75" on the outlet) needs to be cut off the stock pipes. The kit includes upgraded hose clamps and the same high-quality "grippy" silicone hose used in all the FM turbo kits.
We're using this same intercooler in our turbo kits for "normal" Miatas. This means we can buy in greater volume and lower the cost to you. Please note that we cannot ship this product to California as it will not meet emissions regulations.
