70mm EGR Plate - 86-93 Mustang

The BBK Performance 70mm EGR Plate for 1986–1993 Ford Mustang with small block engines is a precision-engineered aluminum component designed to optimize exhaust gas recirculation flow and thermal management. This OEM-style replacement restores proper EGR function on second-generation Mustangs, where factory plates commonly develop carbon buildup, warping, or gasket failure over extended service intervals. The 70mm diameter opening is sized specifically for small block Ford applications, ensuring correct valve seating and emission control compliance.

Manufactured from natural-finish aluminum, the BBK 1502 plate resists corrosion in typical underhood environments and maintains dimensional stability under thermal cycling. At 2.98 lbs, the component integrates seamlessly into the existing EGR valve assembly without requiring engine modification or auxiliary tuning. The plate's flat sealing surface and precision machining ensure repeatable gasket compression and leak-free operation—critical factors for maintaining stable idle quality and preventing vacuum leaks that degrade drivability on carbureted or early EFI powerplants.

This replacement is essential for owners restoring Mustang engine bay integrity, diagnosing rough idle conditions traced to EGR system failure, or upgrading from cracked OEM plates. Whether performing routine maintenance, engine bay reconditioning, or troubleshooting emission-related drivability issues, the BBK 70mm EGR plate delivers the fitment accuracy and material quality required for worry-free reinstallation. Fits 1986, 1987, 1988, 1989, 1990, 1991, 1992, and 1993 Mustangs equipped with small block Ford V8 engines.
