Turn your 11-17 Mustang GT into a high RPM Screamer with ZERO power loss at low RPM while retaining factory level driveability with the 2018 Mustang GT Manifold Kit from JDM Engineering. This kit retains the use of the IMRC’s installed from the factory on all Mustangs 2015+ leading to stellar fuel economy, driveability, and POWER!!! Compared to the GT350 manifold N/A, we find a gain in low end and midrange torque with barely any difference up top. We have seen a 3 horsepower difference, which is marginal when comparing the horsepower per dollar value of the 18 GT manifold. Compared to an IMRC deleted GT350 manifold, we gained 8 MPG crusing around town and saw zero power loss on a procharged 2017 mustang. Let the pictures speak for themselves, we consider our swap kit to be the cleanest install on the market. CUSTOM TUNE REQUIRED.
At JDM Engineering, we did an install on a 2011 5.0 mustang and hands down it was the cleanest install on the market today. Want to see the customers impressions? Click here to see our blog post and read about the power gains from a 2018 manifold swap.
