The JBR HKS BOV Cold Side Charge Pipe Kit for the Ford focus ST is constructed out of 2.5" mandrel bent aluminum. It incorporates a CNC machined flange for a HKS blow off valve and a 1/8" NPT bung for methanol injection. Whether you're upgrading your turbo or just want that distinctive sound of a external blow off valve, we've designed a kit that includes everything to simply and easily defeat the OEM bypass valve and add a HKS external BOV.
The increased diameter and smoother radius tubing of the JBR kit allows for the cold air exiting the intercooler to make its way to the engine faster and more efficiently than the OEM piping.
Making the connections are our custom, 5-ply reinforced silicone couplers. These couplers will not expand under boost and are fuel and oil resistant. Keeping the couplers and piping firmly in place, we've included 19mm wide stainless T-bolt clamps.
In 1994, HKS introduced the first Sequential Blow-Off Valve featuring a unique, pull-type, sequential valve structure and a differential pressure control system. This advanced pull-type relief system allowed for stable operating ranges from low to high boost pressures. Reliable functionality of the Super SQV 4 is unchanged and utilizes the same mounting flanges as all previous generation SSQVs. Super SQV 4 features include a nickel-plated, die-cast metal secondary valve, which is swaged to the primary valve, a stainless steel C-Clip and spring to increase sealing and durability.
The end result is a kit that looks, fits and most importantly...Performs!!
