PDI Big Boss Performance Packages are put together with performance, efficiency, and savings in mind. The Stage 3 Performance Kit combines the popular Big Boss tuner with our high performing intake and exhaust manifolds to ensure the engine can not only take in the most fresh air but also get rid of exhaust as efficiently as possible. Paired with our Big Boss Dual Oil Cooler, this is by far the best it can get on your X15 or ISX. Save now by ordering in a single kit instead of individually!
