APR carbon fiber intercooler ducts for the Porsche 992 3.0T dramatically lower intake air temperature (IAT) by increasing airflow through the ambient air path of the intercooler cores. In doing so, the engine makes more power and sustains power levels for longer—as IAT is kept away from the knock threshold of the engine and IAT-based power reduction safety routines of the factory ECU. Multiple back-to-back wide-open-throttle acceleration tests proved APR intercooler ducts reduced IAT as much as 9.6 degrees C (17.3 degrees F) or 15 percent better than stock! The APR intercooler ducts are made from carbon fiber, allowing the cooling ducts to be formed to the exact shape necessary to fit into the tight engine bay within the 992's rear-end. The vents allow for maximum flow through the system, while continuing to connect the system to the rest of the factory ducting. Everything simply slides into place with no extra hardware required. A gorgeous matte finish with a gloss APR logo adorns the system, giving it a motorsport-inspired feel, which is unfortunately tucked out of view with the rear bumper installed. Testing: The 911 must be tested on the street, rather than a dyno, to capture real world cooling data. This is especially true because of the rear engine design. In real world driving, air is forced through the cooling ducts differently than it is on a stationary dyno, even with excellent cooling fans. During development, APR engineers fully instrumented the engine to find the limitations of the factory hardware. It was quickly determined the factory intercoolers struggled with airflow through the ambient cooling paths. By redesigning the cooling ducts, more high-pressure ambient air could be forced through the system to maximize effectiveness of the coolers. To illustrate their importance, wide open throttle acceleration tests were conducted for roughly 11 seconds, both with stock cooling ducts and APR cooling ducts. IAT was measured post-intercooler with high-quality thermocouples. Ten back-to-back tests were conducted with each setup, and the results were averaged together. With the stock ducts in place, IAT rose to 66.2 degrees C (151.2 degrees F). This is above the factory knock threshold of 60 degrees C (140 degrees F) and is approaching the ECU power reduction limiter at 70 degrees C (158 degrees F). Once this IAT threshold is crossed, the ECU will begin aggressively reducing engine power to protect the engine. By simply swapping to the APR intercooler ducts, IAT dropped 15 percent, or 9.6 degrees C (17.3 degrees F), leveling off at 56.6 degrees C (133.9 degrees F). This is below the knock threshold and safely away from the power reduction threshold! APR Intercooler ducts are a simple and cost effective upgraded to the 992 3.0T and should be considered by any customer, at any stage of performance, looking to maximize the performance of their 911! Product features: * Improved intake air temperature (IAT) by 15 percent over stock * Organic matte carbon fiber design with gloss APR logo * Lightweight material and design * No extra hardware required * Plug-and-play upgrade * Retains factory intercooler post-housing ducting * Excellent performance per dollar upgrade for the Porsche 911 * Emissions compliant

Holley is the new standard in EFI! The Holley EFI LT1 Gen V Ultra Lo-Ram intake manifold kits are designed for GM Gen V LT engines equipped with GM LT cylinder heads. They will work with OE or aftermarket cylinder heads. The Ultra Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications. The front-feed base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood. The Ultra Lo-Ram provides a very low-profile modular intake manifold along with various fabrication flanges to aid the fabrication of special throttle body adapters or inlet ducts for custom installations. Whether you're engine swapping your classic car or need to manage added horsepower in your twin-turbocharged drag radial race car, Holley EFI has the solutions you need to get your project up and running better than ever! Features: * Designed for GM Gen V engines equipped with GM LT type cylinder heads * As-cast aluminum (satin) and black powdercoat finishes available * 105mm diameter throttle body opening accepts OEM 4-bolt LS/LT DBW or Holley LS/LT throttle bodies * Engineered for forced induction (supercharged or turbocharged) engine applications with peak power at 7,000-8,000 rpm depending on the application * Only 0.97 in. taller than a factory LT1 manifold provides maximum clearance under a stock or mildly modified hood * Modular design and front entry plenum flange allows design and fabrication of special throttle body adapters or inlet ducts for custom installations—base manifold, plenum top, throttle body adapter available as separate kits * Clears C7 Corvette cowls and hoods without modification * Available for OE direct fuel injection only or with added port fuel injection provisions * Kits with port injection provide high volume fuel rails with 3/4-16 O-ring ports (8 AN). Mounting hardware is included * Ultra Lo-Ram kits with a burst panel flange are available, Ultra Lo-Ram billet burst panel duct is offered separately (PN: 300-608 clear anodized, PN: 300-608BK black anodized)
