Fuel Rail Throttle Body & 102mm Low Intake Manifold LS1 LS2 LS6 4.8L 5.3L 5.7L

Fuel Rail Throttle Body & 102mm Low Intake Manifold for LS1 LS2 LS6

This fuel rail, throttle body, and 102mm low intake manifold kit delivers the air and fuel path components for 4.8L, 5.3L, and 5.7L LS series engine builds used by builders and swap installers.

Overview

This intake manifold kit bundles a 102mm low-profile manifold with a matching throttle body and fuel rail set for LS1, LS2, and LS6 engines. The manifold routes intake air into the cylinder heads while the throttle body meters airflow and the rails feed fuel to the injectors. It suits engine swap projects and performance rebuilds where a low-clearance intake and larger throttle bore are wanted.

Built For Performance

• 102mm throttle body bore supports higher airflow than smaller stock openings
• Low profile manifold helps clear hoods and swap bays with limited vertical space
• Fuel rail set feeds eight injectors on LS-series V8 engines
• Fits 4.8L, 5.3L, and 5.7L displacement LS engines
• Compatible with LS1, LS2, and LS6 cylinder head layouts

Fits These Machines

• for 4.8L LS series V8 engines
• for 5.3L LS series V8 engines
• for 5.7L LS1 engines
• for 5.7L LS6 engines
• for 6.0L LS2 engines

On-The-Job Use

• Engine swap builds needing a compact intake and throttle body package
• Performance rebuilds seeking a larger throttle bore than stock
• Boosted or cammed LS builds upgrading the intake side
• Project cars with tight hood clearance

Specs At A Glance

Good To Know

Q: Do I need a tune after fitting this intake and throttle body? A: Yes, changes to throttle body bore and airflow usually require ECU calibration to run correctly.

Q: Will the stock fuel lines connect to these rails? A: Fitment depends on your specific engine and chassis setup, so confirm line routing and connection style before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
