BTR LS Trinity Intake and Matching Fuel Rail Package

Select one BTR LS Trinity intake manifold and one matching BTR fuel-rail kit. Each option names both exact part numbers; quantity is one manifold plus one rail kit.

Head-port selection: TRA-1 is cathedral port; TRA-3 is LS3/L99-style square port; TRA-7 is LS7-specific. These are not interchangeable and are not Gen V LT intakes. Confirm your cylinder heads, not just the vehicle name.

Rail selection: Standard single-injector choices use FRK-02 or FRK-02-12. Dual-injector (-2I) choices include FRK-2I only, following BTR’s individual manifold instructions. Dual-injector package prices are the manifold plus the correct FRK-2I kit, not the manufacturer configurator’s incompatible standard-rail selection.

Not included: Injectors, throttle body, throttle-cable bracket, fuel lines, or tuning. FRK-02-12 and FRK-2I require separately sourced adapter fittings. Burst-panel (-BP) choices have burst-panel provisions; panel/frame hardware is not included unless separately ordered.

Installation: Check injector dimensions, fuel-line routing, throttle-body pattern, hood clearance and ECU calibration. BTR warns that the LS truck accessory drive does not fit Trinity intakes; truck/swap installations require compatible accessory arrangements. Dual-injector bodies must not exceed 0.8125 inch diameter.

Manufacturer photo is illustrative; finish, runners, and fuel rails follow the selected part numbers. This is a manifold-and-rail package, not an assembled complete fuel system.

Shipping estimate: Provisional combined component weight is 30.8–35 lb, depending on the selected manifold and rail kit. This adds BTR’s individual weight fields, provisionally interpreted as pounds because the source does not label units; it is not a measured packed shipment. Planned combined carton is approximately 30 × 16 × 16 inches with a 1 lb packing allowance (estimated packed weight 31.8–36 lb). Final carton, packing weight and dispatch availability require confirmation before shipping.

Vehicle references and required intake selection

Vehicle search matches this package family, not every option. Select the manifold that matches the installed cylinder-head ports. These are performance installations requiring the clearance, accessory-drive, injector and calibration checks above.

• 2010–2015 Camaro SS (LS3/L99), 2008–2013 Corvette Base and 2010–2013 Corvette Grand Sport (LS3), 2008–2009 Pontiac G8 GT (L76), and 2009 G8 GXP (LS3): select a TRA-3 square-port option.
• 2006–2013 Corvette Z06, 2013 Corvette 427 Convertible, and 2014–2015 Camaro Z/28 (LS7): select a TRA-7 LS7 option.
• 1997–2004 Corvette Base (LS1), 2005–2007 Corvette Base (LS2), 2001–2004 Corvette Z06 (LS6), 1998–2002 Camaro Z28/SS and Firebird Formula/Trans Am (LS1), 2004–2006 Pontiac GTO (LS1/LS2), and 2004–2007 Cadillac CTS-V (LS6/LS2): select a TRA-1 cathedral-port option with compatible factory-style heads. Do not select TRA-1 for LS3/L99/LS7 heads. Vehicle listings identify the engine family; hood, throttle-body, fuel-system and accessory-drive compatibility still require installation checks.

V6 models, stock 2014-and-newer Corvette LT engines, and other Gen V LT applications are not covered by these LS intake choices. Modified or swapped vehicles must be evaluated by their installed engine, heads, accessories and available space.
