About BBK
BBK develops and manufactures bolt-on induction, exhaust, and engine-airflow components for American performance vehicles. Its Mustang throttle-body family uses matched throttle-body and EGR-spacer bore sizes for the intended intake configuration.

- No related store product is linked because the matching throttle body must be verified by exact part number and current ACTIVE status.
FAQ
What is the 1502?It is a 70mm EGR spacer plate for the listed Ford Mustang 5.0L application and matching BBK 70mm throttle body.
Why must the spacer match the throttle body size?BBK requires the same bore size so the intake path does not step down between the throttle body and spacer.
Which throttle body is the matching BBK part?BBK identifies 1501 as the corresponding 70mm throttle body for the covered Mustang application.
Are gaskets included?Yes. BBK states that new gaskets are included with the spacer plate.
What material is used?The spacer is CNC-machined from a high-quality 356 aluminum casting.
Is the part covered by a CARB Executive Order?Yes, when used in the covered configuration described by CARB Executive Order D-245-4.
Will it fit a 75mm throttle body?No. A 75mm throttle body requires the matching 75mm EGR spacer rather than this 70mm part.
How long does installation take?BBK lists an approximate installation time of one to two hours and requires appropriate safety equipment.
Installation Instructions
- Confirm the package label shows BBK 1502, the vehicle is a supported 1986-1993 Mustang 5.0L, and the throttle body bore is 70mm.
- Allow the engine to cool, disconnect the battery, and review the current BBK instruction sheet before disassembly.
- Remove the intake tube and disconnect the throttle-body and EGR-related connections identified by BBK.
- Remove the existing spacer and clean the mating surfaces without allowing debris into the intake.
- Install the supplied gaskets and 70mm spacer in the orientation shown by BBK, then reinstall the matching throttle body and connections.
- Tighten hardware evenly to the current BBK specifications, reconnect the battery, and complete any required idle relearn.
- Start the engine, inspect for vacuum leaks, coolant leaks where applicable, binding, or diagnostic faults, and recheck the installation after the first heat cycle.
