Utilizing the proven short runner tunnel-ram style, the Edelbrock Performer RPM Air-Gap LT4 provides the next step up in performance for LT4 engines. This manifold is a direct stock replacement for OEM equipment with all required emissions features. The patented Air-Gap™ design delivers a cooler and denser air stream for maximum power output, and helps with the "hot soak" problems that LTx engines are known for. The Performer RPM Air-Gap intake manifold is designed to work with either our 52mm or 58mm throttle bodies with no modification. It also accepts early and late OEM LT1 style throttle bodies and fuel rails. This manifold is ideal for upgrading your LT1 with LT4 cylinder heads or AFR style heads with raised intake ports.
NOTE - DOES NOT FIT LT1 WITH OEM HEADS!
