Blessed Performance has the SPE Motorsport Explorer ST Cold Side pipe.
The factory cold-side pipe on the Explorer ST is one of the biggest airflow bottlenecks on the platform. Ford crimped the OE pipe down to nearly one inch in the tightest section, which kills flow and becomes a weak point as boost increases. We built our SPE Cold Side kit to correct that restriction, improve reliability, and give owners an option to run a proper bypass valve on later model STs that no longer include one from the factory.
This is a direct-fit upgrade for all Explorer ST model years and replaces the fragile plastic OE pipe with a high-quality 5-ply silicone assembly designed for higher boost and improved throttle response.
