Product Details

The BBK 1536 Power-Plus twin throttle body delivers a significant boost in airflow and horsepower for 1985-1988 GM vehicles equipped with 305 or 350 cubic inch Tuned Port Injection (TPI) engines. This direct bolt-on upgrade features 58mm bores that dramatically improve throttle response and engine breathing over the restrictive factory units.

Premium Construction and Features:

  • Cast from high-quality 356-T6 aluminum alloy for strength and light weight
  • Precision CNC-machined on state-of-the-art equipment for perfect fitment
  • Double-sealed bearings ensure smooth, reliable operation
  • O-ringed throttle shafts prevent vacuum leaks
  • Precision die-stamped linkages for consistent throttle control
  • Twin 58mm bore design maximizes airflow to both cylinder banks

Installation is straightforward and can be completed in under an hour with basic hand tools. This throttle body is designed as a direct replacement for the factory TPI system, requiring no modifications or tuning for most applications. Experience improved acceleration, better top-end power, and enhanced engine efficiency with this proven performance upgrade.

Ordered a rim at 11am, I had it the very next day, unbelievable delivery time by Autoplicity. I'm very pleased with how smooth they operate, I will be ordering again from them in the future.

Convenience

Prices were good and the order shipped promptly. The email notice of shipment was a little late. It came after the order had arrived.

Product delivered as expected within 4 days. Lowest price on the web. No complaints.

This was an easy transaction, keep me notified thoughout the entire shipment. Price is what got my attention in the first place. I will be back for future needs.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
