SEMA 2015: Edelbrock Unveils Their Cross-Ram LS3 Intake Manifold


The LS-series engines have been called everything from the new Flathead Ford and Small-Block Chevy, the greatest overall engine of all time. You can make a case for each; with the LS’ compact, lightweight design to its expansive aftermarket and enthusiast support, its popularity isn’t going away anytime soon.

Edelbrock has certainly been there for the enthusiast, but despite the LS3’s recent departure from the GM lineup, the timing for their new Cross-Ram LS3 intake manifold couldn’t have been better. They’ve unveiled it during SEMA 2015, and we were simply awestruck by its design. Learn more about it from the official release below!

Official Release:

Edelbrock Cross-Ram LS3 Intake Manifold

TORRANCE, CA – Edelbrock is known for the Cross-Ram intake manifolds since the 1950’s. Now, Edelbrock has taken that same idea and applied it to modern Gen IV engines with LS3, L92 and L76 rectangular port cylinder heads.

The Cross-Ram LS3 intake (#7141) is ideal for anybody ready to combine dynamic looks with outstanding performance between 1,500-7,000 rpm. The unique dual-plenum design features 13” long runners with flanges that will accept 90mm GM LS3 throttle bodies. This manifold design is also ideal for twin turbo applications under the hood. When matched with high flowing air filters and inlet tubes, the dual-plenum system gives neck-snapping performance with plenty of options for engine builders and tuners.

Matching the performance are the great looks with powder coated red plenums contrasted with a light silver base. The machined highlights and bright zinc fasteners are added details to this unique assembly. Fuel rail kit (#3654, available separately) is conveniently located under the manifold base eliminating obtrusive plumbing and resulting with a cleaner appearance.

Dyno testing resulted with gains of 27 horsepower and 28 ft-lbs. of torque over a popular aftermarket intake manifold when used with Edelbrock hydraulic roller camshaft (#2219, available separately), stock GM LS3 cylinder heads and 60 lb. fuel injectors.
