pTR Carbon Intake Manifold

The Lingenfelter Carbon pTR Intake Manifold is a tunnel ram architecture engineered for LS3 and LS7 engines, combining premium materials for flexible and powerful performance. Its construction features a PA6GF30 glass-filled nylon lower manifold for reduced heat soak and a high-strength carbon fiber plenum with a foam core flange for improved strength-to-weight ratio and reduced heat soak to the intake charge. This intake offers unique modular velocity stacks with configurable runner lengths of 6.5", 8.0", and 9.0", allowing for tuning to optimize the engine's power curve for specific applications – shorter runners for high RPM, longer for mid-range torque, and mixed lengths to smooth the curve. It includes two MAP sensor locations, two 1/4" NPT ports (for PCV, purge solenoid, etc.), and one 1/2" NPT port (for brake booster or IAT). Additional features include provisions for three injector body lengths and sixteen NOS bosses. Installation is facilitated by included stainless steel hardware and molded port, plenum, and throttle seals. The intake manifold can be reversed on the engine, and it boasts an anodized billet throttle flange available in standard red and black, with optional custom colors. Optional PD ultralight billet -8 fuel rails are also available. The combination of materials results in a significant weight saving compared to traditional aluminum tunnel ram manifolds. Important Note: This manifold does not fit underhood on late model vehicles and is best suited for resto-mod, off-road race trucks, race boats, and hot rods.
