If you can get air out the turbo, through the intercooler and into the engine faster, you will get the benefit of increased spool-up. Along with the quicker spool-up you will also get your torque peak sooner. This is why these pipes help dramatically. They are much bigger and less restrictive, and provide the path of least resistance. You will notice better boost response immediately after installing them on your vehicle, guaranteed! All of our pipes are TIG welded and then finished on the inside to help smooth out airflow. All SFR intercooler pipes are bead rolled or barbed on the ends to prevent your silicone hoses from slipping off under boost.All SFR hard pipe kits come with all factory fittings, a silver finish (polishing is additional), silicon hoses (in red, blue or black) and stainless-steel hose clamps. You have your choice of 6061 aluminum or 304 stainless-steel intercooler pipes. The Speed Force Racing intercooler pipes take the place of the small diameter, restrictive factory pipes. These are how the pipes should have come from the factory. You also remove the 45 degree rubber boot on the turbo discharge that shrinks with age/heat and causes a major restriction on airflow. Another problem area that is alleviated is the reducer hose that connects to the throttle body and causes so much grief. SFR pipes have a gradual transition that meets up to the factory throttlebody perfectly.These pipes come with all factory fittings, a silver finish (polishing is additional), silicon hoses (in red, blue or black) and stainless-steel hose clamps. NOTE: These pipes will not fit on cars with the airflow meter in the stock location.
