The LS1/LS6 cathedral port intake is the answer to your low hood clearance woes when dropping that Gen III 4.8, 5.3, or 5.7 liter* into your classic ride. Either of these legends is the perfect choice for your general cruising needs, BUT if your looking for every last pony for your weekend warrior you'll enjoy a 6 to10% gain in peak power numbers from the venerable LS6 intake. A key package component to placing the C5 Z06 into the history books.  Complete intakes include OEM fuel rail, and refurbished OEM injectors.  NOTE: While we strive to provide our customers with the highest quality product possible, these are used refurbished take offs. They will show signs of installation, and use. We highly recommend the use of fresh gaskets.  * This would include early 6.0 engines, or any LS platform with GEN III cathedral port heads as shown in the photo below.
