These billet compressor wheels are much stronger than cast compressor wheels and are designed to flow more air. With a more aggressive blade design and the nose and hub designed to be significantly smaller allowing for larger blade size. The increase of blade surface area allows them to flow more air into the engine. This more efficient wheel lowers the intake temperatures to give you more horsepower and allowing you to stay in the throttle longer.
•Will not fit 2004.5-07 (build date 11/04 and later). The 03 style wheel measures about 59mm and the 05 style measures about 56mm.
****If you do not have access to a caliper or micrometer, the part number of the OEM wheel is printed onto the back of the wheel. Remove the wheel and look for the part number. You may need to use brake parts cleaner to clean off any oil to read it. Do not use anything other than brake parts cleaner. Acetone or similar cleaners will remove the part number. The '03 wheel part number is 722142-0020M. The '05 wheel part number is 722142-0025M.
Special Note: This turbo has a reverse thread - meaning you turn the compressor wheel to the right to loosen. No need to torque the Wicked Wheel on. Simply snug the Wicked Wheel until it fully seats. It will self-tighten to full torque.
