Eliminate the heavy stock fan and free up power and gas mileage! Our kits include a black powdercoated laser-cut shroud, a high quality SPAL fan, a harness, hardware, appropriate brackets, and instructions for installation. Our shrouds also have flapper valves cut into them (included) for improved highway cooling. Typical gains are about 15hp on a V8 and about 10hp on an I5. Gas mileage gains are typically 1-2mpg. 2008+ H3’s will need a patch in the ECM to operate the fans, this kit includes a FREE voucher to have your ECM patched by us. This can also be done by anyone with HP Tuners. With the 2006-2007 H3’s, the fan will run off of our harness, which gets signals from a temperature sensor you will install into your radiator hose, and also from the A/C. Typical gains are about 10hp on an I5. Gas mileage gains are typically 1-2mpg. Click here for main installation instructions! Subharness instructions (04-07). Subharness Instructions (08+).
