High-Performance LS Engine Intake Manifold Summary<\/h2>\n

Chasing 800+ horsepower? The intake manifold<\/b> is purpose-built for serious high-RPM racing, delivering reliable top-end power from 7,000\u20138,500+ RPM. This heavy-duty LS engine intake manifold<\/b> features extended-length tuned runners and an oversized high-rise plenum designed to maximize airflow at extreme RPM. If you are upgrading your LS engine<\/b> with a premium fuel injection manifold<\/b> that balances structural durability with maximum volumetric efficiency, this LS aluminum intake<\/b> provides the ultimate race-proven platform. Engineered as a heavy-duty EFI intake manifold<\/b>, it includes matching aluminum fuel rails for a true bolt-on installation on high-displacement V8 street and strip setups.<\/p>\n

Whether you are plumbing a large turbo system, building a supercharged track weapon, or executing a max-effort naturally aspirated race engine, this LS intake manifold<\/b> eliminates the restrictive air bottlenecks common with factory composite units. Choosing this specific LS3 intake manifold<\/b> ensures that your rectangular port configuration receives uniform air-fuel distribution across all cylinders. Upgrade your factory top-end today with this LS high ram intake<\/b>, engineered explicitly to handle the intense pressure and thermal demands of high-combination forced induction.<\/p>\n
