BTR Equalizer Intake and FRK-01 Fuel Rail Package

Choose one BTR Equalizer intake manifold and receive one BTR FRK-01 fuel-rail kit. This listing offers the four base manifold-and-rail combinations from BTR’s BTREQ package.

• Equalizer 1 cathedral port: IMA-01 natural or IMA-01-BLK black.
• Equalizer 3 square port: IMA-03 natural or IMA-03-BLK black.
• Every selection includes one FRK-01 fuel-rail kit.

Not included: Injectors, throttle body, steam-vent crossover, and throttle-cable bracket. This is the base package, not BTR’s full optional-add-on configurator. Images are illustrative.

Fitment: Select the manifold for your cylinder-head intake-port design. Cathedral and square-port variants are not interchangeable. Engine swaps require matching heads, throttle body, injector dimensions, fuel lines, hood clearance, and tuning; this is not universal bolt-on fitment.

Availability: BTR’s black manifold choices are marked backorder as of September 22, 2026. Contact SMGspeed for current lead time; no ship date is guaranteed.

Injector hardware: Truck-length injectors require four BRKT-02 rail brackets, sold separately. Equalizer 3 with LS1-style injectors requires BTR lower O-rings INJ-ORING3-8.

Engine reference: Equalizer 1 is for LS1/LS2/LS6-style cathedral heads; Equalizer 3 is for LS3/L99-style square-port heads. A vehicle-year match alone does not select the correct manifold. Camaro references require the appropriate LS V8, not V6; Corvette Z06/LS7 heads are not covered by the square-port option; G8 V6 is excluded. Check engine and cylinder heads before ordering.

Provisional shipping weight: Natural combinations 32.5 lb; black combinations 34.5 lb, calculated from BTR’s individual manifold and rail catalog weights. Pounds are inferred because the catalog omits units. A provisional 30 × 16 × 16 in outer box with a 1 lb packaging allowance is used for shipping estimates (estimated total 33.5 lb natural / 35.5 lb black). These are not manufacturer-confirmed packed measurements.

Factory-engine vehicle references

Vehicle search identifies this package family, not every manifold option. Verify the installed heads, hood clearance, throttle body and fuel system before ordering; swaps and modified engines require individual checks.

• Equalizer 1 (IMA-01 or IMA-01-BLK): 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), with compatible cathedral-port heads.
• Equalizer 3 (IMA-03 or IMA-03-BLK): 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), with compatible square-port heads.

Not for factory LS7 heads, V6 engines or Gen V LT engines. The 2001–2004 LS6 Corvette Z06 reference applies only to Equalizer 1; later LS7-powered Z06 and Camaro Z/28 applications are excluded.

Equalizer 3 installation limits: BTR states that truck accessory drives are not compatible. C5 cowl clearance can require minor modification to the intake. Do not assume stock-accessory or no-modification installation from an engine-family match.
