Performance Design Carbon pTR intake manifolds combine high-quality materials into a flexible and powerful tunnel ram architecture. PA6GF30 glass-reinforced nylon (lower) and 5-layer carbon fiber (upper) shells combine for lightweight, strong, and heat-resistant performance. Offering unique modular velocity stacks enabling 6 1/2 in. to 9 in. runners, multiple accessory port and sensor options along with other custom features, these high-performance manifolds offer easy configuring for a variety of hot rod builds, and can even be reversed on the engine. The plenums feature high-strength carbon fiber with high-temperature epoxy for improved strength-to-weight ratio and reduced heat soak to the fresh air charge. The polymer lower runner pack resists heat soak from the cylinder heads and hides all the ports/sensors in the valley. This combination of materials offers a 10 lbs. weight savings over competitive aluminum tunnel ram manifolds. These custom assemblies are designed for resto-mod, off-road race trucks, race boats, and hot rods where hood clearance is not an issue (they will not fit under late model vehicle hoods). Other product features and specifications include: * Modular velocity stacks for 6.5 in., 8.0 in., and 9.0 in. runner lengths * Raised velocity stack runner entries * Foam-core flange * Anodized billet 105mm forward-facing throttle body flange accepts 90-105mm throttle body * Two MAP sensor locations (front and back) * Two 1/4 in.-NPT ports for PCV, purge solenoid, etc. * One 1/2 in.-NPT port for brake booster or IAT * Tested to over 50 psi of boost * Nitrous nozzle bosses on outboard and valley side of each runner (16 total) * Includes stainless steel hardware for installation * Provisions to run 3 different injector body lengths * Includes molded port, plenum and throttle seals * Optional Carbon pTR ultralight billet -8 AN fuel rails (sold separately) * Optional medium or short velocity stacks (sold separately)

Stick on horsepower! Heatshield Products I-M shields reduce heat radiating from the top of the motor significantly. This creates a more dense fuel and air mixture, in turn creating more power. Think of them as intercoolers for your intake, with the same physics and chemistry, but just a different execution. They include heavy-duty adhesive that will stick to any clean, semi-smooth surface. Simply degrease and clean the surface, wipe it with pre-paint cleaner or isopropyl alcohol, let it dry, and then firmly press the Heatshield Products I-M shields onto the underside of the intake manifold. Features include: * Withstands 1,100 degrees F radiant continuous, 2,000 degrees F intermittent * Adhesive good for 300 degrees F * Lower intake temperatures * Increases up to 12 RWHP
