Top Feed Port Injection with Included Fuel Rail The CSF Manifold includes an extruded fuel rail which can be attached to the outlet side of the manifold. The AN-8 fuel rail comes with feed and return -8 internal hex plug fittings from Radium Engineering for a plug and play installation. - Fuel rail aperture for each cylinder is an optimized 7mm opening for compatibility with most commonly used high performance injectors - CSF recommends using Injector Dynamics (ID) injectors for the best performance – the most commonly used injector for this engine has been ID model # 1050.34.14.14.6 (qty 6) - Anodized CNC machined injector hats (qty 6) are included in the supplied hardware kit to accommodate short height injectors aka “shorties”

Individual Nitrous / Methanol Injector Ports A 1/8th NPT port on each cylinder runner can be used for nitrous or methanol injection. The CSF manifold allows for maximum spray control and even spray distribution throughout the engine. Vacuum and Parameter Pad CSF has included a 3 port pad into the machining of the tank on the manifold inlet side. The ports can be used to measure additional parameters or as an additional vacuum source. The three 1/8 th  NPT ports can be plugged with the included hardware kit if they are not used. Easy Access to Spin-Off Oil Filter With Counter Balanced Design CSF incorporated a recessed design towards the back of the manifold that allows easy access to the spin-off oil filter. This means you do not have to remove your manifold every time you want to change your oil. While this design feature isn’t unique to the CSF manifold, CSF is the only company to account for the airflow issues such a recess can create. CSF Engineers designed and tested a counter balanced protrusion using SolidWorks CFD software. This protrusion sits above the recess to offset the airflow tabulations. This feature ensures smooth air delivery into the rear of the core for the best possible cooling. Air Inlet Divider The inclusion of an air divider welded into the inlet side tank of the manifold is another exclusive feature of the CSF manifold. With the length of the manifold, the engineers at VF Engineering wanted to make sure that the volume and velocity of air was consistent to all cylinders. After extensive simulations in SolidWorks CFD software, an air divider was added to the design to ensure the best possible and equal cooling performance to each cylinder of the engine. Airflow to the back of the manifold (cylinders four, five, and six) should be equal to the airflow to the front of the manifold (cylinders one, two, and three) for the best possible performance. Breather Ports for Inlet/Outlet of Water Tanks Two 1/8th NPT ports are located on the top of the back water plate. These ports can be used to measure inlet/outlet water temps as well as used as breather ports to help in the bleeding procedure. 1/8th NPT plugs come included in the supplied hardware kit. Please follow OEM BMW or Toyota bleeding procedure which takes roughly 15 minutes to complete. Thermal Rejection Competition Spacer Made from KIYLEX®, a patented revolutionary high-performance final stage polymer. KIYLEX® is as strong as aluminum and can withstand temperatures up to 1100°F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier reduces manifold temperatures which helps lower Intake Air Temperatures (IATs), improve charge air cooler efficiency, and combats heat soak. CSF is the exclusive distributor for the KIYLEX® Intake Manifold Spacer for the B58 Motor. The addition of the Thermal Rejection Spacer is especially useful for Drag/Roll-Racing Events where vehicles typically sit in staging lanes in-between racing. This causes extreme heat soak to the liquid-to-air manifold as there is not sufficient airflow passing over the front mount heat exchanger when the car is idling (which is responsible for cooling the charge air fluid that runs through the manifold). This causes the starting IATs on subsequent runs to be higher than on the initial run. The CSF Manifold is made from Billet Aluminum and 100% TIG Welded for strength, which allows it to be able to withstand higher boost pressures compared to the OEM plastic manifold. Aluminum has higher thermal conductivity than plastic resulting in a higher rate of heat transfer between the cylinder head and manifold. Adding the Thermal Rejection Spacer reduces heat transfer between the two metal components (cylinder head & manifold). The spacer absorbs the heat from the cylinder head and dissipates it rather than transferring it to the manifold. The CSF Thermal Rejection Competition Spacer was designed for vehicles competing in motorsports who demand the absolute best cooling in order to gain a competitive edge. However, including this spacer offers significant advantages to any vehicle. Hardware Kit, Well Thought-Out Instruction Manual The supplied hardware kit includes several brackets, bolts, washers, and fittings for installation. This is an industry-exclusive feature to the CSF x VF Engineering design, and was extremely difficult to not only engineer, but to manufacture as well. An array of items come vacuum packaged with corresponding letters listed on an easy to use Bill-of-Materials List (BOM) along with exploded diagrams and a simple order of operation procedure list to follow for installation. Made with mechanics, technicians, racers and DIY enthusiasts in mind. Rear Water Plate Breather Ports & Overflow Tank Fitting CSF added new -6 ORB 90 Swivel fitting with the ability to clock. This gives the installer more options for running the overflow return line. The line can still be run directly to the OEM overflow tank like the factory configuration. This new fitting also allows you to hide the return line for a “clean-tucked” return route to the OEM overflow tank located at the front of the engine bay. The kit includes 40 inches of overflow line hose that can be cut to size based on preference of water line routing. CSF also sourced and includes an OEM quick connect fitting for the factory overflow tank. This makes the connection to the overflow tank more secure. The fitting comes pre-installed on the overflow line for an easy and quick to installation. Slotted Mounting Tabs Positioning the manifold in the engine bay is fairly straightforward. However, it can be a little frustrating to get the bolt holes on the intake side mounting tabs lined up perfectly. After doing a few test fittings CSF realized this could be resolved my slotting the mounting tabs. This allows the bolts to be installed before final positioning adjustments and makes installation a bit easier.
