Mercury Grand Marquis Parts & Accessories

Shop Mercury Grand Marquis exhaust, intake, transmission and axle parts at Black Ops Auto Works. Compare BRExhaust replacement kits, Stainless Works exhaust options, K&N filtration and FTI converters. Choose components for the exact generation, installed powertrain and service or upgrade you have planned.

BRExhaust and Stainless Works Exhaust Options

For exhaust maintenance, compare BRExhaust kit 106-0618 and the separate kit for the stated 2003–2011 Grand Marquis 4.6L application. For a larger project, review Stainless Works header and chambered-muffler exhaust options independently. Match body, engine, connections and supplied sections, and confirm the exact emissions application where relevant before planning installation.

FTI Transmission Project References

Compare FTI converter choices by the installed AODE, 4R70 or 4R75 transmission application, flexplate and mounting bolt circle. Review engine combination, intended use and supporting build requirements with your installer before selecting a stall specification. Plan transmission and converter compatibility together rather than choosing by a rating alone.

Axle and Brake-Service Applications

Match Eaton or Yukon differential, gear and service parts to the actual axle housing, spline count, shafts, bearings and ratio. For brake maintenance, identify the installed calipers or drums and match complete Grand Marquis coverage, axle position and dimensions. Review supporting hardware for each repair before combining components.

K&N Intake, Filtration and Engine Service

Compare the K&N Typhoon intake for the stated 2010–2011 Grand Marquis 4.6L application with drop-in filter coverage for earlier production. Match the exact engine, airbox or intake system and installation needs. For engine rebuilding, choose Clevite, Windsor or COMP Cams components by the actual engine variant and measured assembly specifications; confirm ignition applications separately.

Frequently Asked Questions

How do I choose an exhaust kit for my Mercury Grand Marquis?

Match the kit to your Grand Marquis’s year, engine and body configuration. Check connection locations, the sections supplied and any required installation hardware before ordering.

How do I choose a catalytic converter for my Grand Marquis?

Verify the manufacturer’s exact Grand Marquis application, engine and exhaust configuration. Check the converter’s emissions application and installation requirements separately; a listing for a related model alone does not confirm suitability.

How do I choose a torque converter for my Grand Marquis?

Identify the exact installed transmission, engine and flexplate, then match converter mounting and bolt-circle requirements. Discuss the build and intended use with your installer before selecting a stall specification.

How do I choose axle parts for my Grand Marquis?

Identify the installed housing, shaft dimensions, spline count, bearings and gear ratio. Match each differential, gear set and supporting rebuild part to that assembly and the planned work.
