The OEM cold side intercooler pipe is known to crack and leak under high boost pressure. Our premium upgrade solves that issue with a durable, high-flow design built to perform. Crafted from mandrel-bent aluminum tubing, this charge pipe ensures smooth, unrestricted airflow for maximum efficiency. It's finished in our signature Sinister Blue powder coat, adding corrosion resistance and a bold, custom look under the hood. With a larger diameter than stock, this charge pipe increases airflow to the engine, reducing turbo lag and improving throttle response. The result? More horsepower, better fuel efficiency, and a noticeably quicker spool-up—whether you’re towing, daily driving, or upgrading for performance. Each kit includes high-grade silicone boots, stainless steel T-bolt clamps, and all necessary hardware for a secure, leak-free installation. We even include a new O-ring and retaining clip for a complete (unlike most of our competitors), reliable setup right out of the box. Best of all, it’s CARB-compliant and 50 state legal—so you can enjoy real performance gains without compromising emissions compliance. Experience improved reliability, airflow, and engine response with the Sinister Diesel Cold Side Charge Pipe—engineered for serious Ford owners who expect more from their truck.
