Want to add power and looks to your V6 Mustang? Look no further, we have the coolest air intake for the 05 up 4.0L. We didn't just build a bigger version of the stock Mustang intake we designed a new system from a clean sheet to take advantage of the new front mounted throttle body. Awesome test results with the 4.0L - power gains of 10-14hp across the rpm range without a programmer. Further gains can be had with a programmer tune.
