Throttle Body Adapter Kit for Enhanced Performance

Breathe new life into your Ecotec with the BK Racing 4.3 Throttle Body Adapter Kit — the best complete plug-and-play adapter for bolting a larger 72mm 4.3L V6 throttle body onto stock 2.2L or 2.4L Ecotec intake manifolds. Replace the restrictive factory 58mm throttle body with the bigger 72mm bore for dramatically improved airflow, quicker throttle response, better top-end power, and enhanced efficiency — all without major fabrication or custom intake work.

This all-in-one kit includes everything needed for a clean, reliable conversion: adapter plate with mounting bolts, throttle cable bracket, Cavalier-to-4.3 TPS pigtail adapter, and wiring harness — no extra parts or guesswork required. On 2.4L manifolds, the top-left bolt hole may not align perfectly due to minor casting differences; the remaining hardware secures the plate firmly without issue.

Perfect for naturally aspirated, supercharged, or turbo Ecotec builds chasing straightforward gains — whether you're in a Cobalt, HHR, Cavalier, Ion, G5, or custom swap.

Kit Includes:

• Precision CNC-machined adapter plate with mounting bolts
• Throttle cable bracket for secure routing
• Cavalier-to-4.3 TPS adapter pigtail
• Wiring harness for plug-and-play TPS connection

Performance Benefits:

• Increases intake volume for noticeable throttle response and top-end power
• Supports higher airflow demands in tuned or boosted setups
• Eliminates the need for custom intake or welding
• Maintains drive-by-wire or cable compatibility with proper tuning
• Simple bolt-on upgrade for real-world gains without complexity

Compatibility:

• 2.2L Ecotec manifolds (L61, LAP)
• 2.4L Ecotec manifolds (LE5, LE9, LAT)
• Vehicles: Chevrolet Cavalier, Cobalt, HHR, Malibu; Pontiac Sunfire, G5, Solstice; Saturn Ion, Sky, Vue, Aura; and custom Ecotec swaps
• Fits GM 4.3L V6 throttle bodies (72mm bore, 2003-2014 style)

Installation Note: Direct bolt-on with included hardware. 2.4L manifolds may require using 3 of 4 mounting holes — secure fit guaranteed. ECU tuning recommended to optimize for larger TB and eliminate any drivability issues. Off-road and competition use only.
