Product Details

The Allstar Performance ALL25991 is a high-flow carburetor spacer designed for 4500-style flanges. Constructed from durable polymer material, this spacer provides thermal insulation between the carburetor and intake manifold while improving fuel atomization and throttle response.

Key Features:

  • 1 inch thick spacer height for optimal plenum volume
  • Open center design maximizes airflow
  • Lightweight polymer construction resists heat transfer
  • 4500-style flange pattern for Dominator-style carburetors
  • Reduces heat soak to keep fuel cooler
  • Easy installation with standard carburetor mounting hardware

This carburetor spacer is ideal for racing applications where maintaining consistent fuel temperatures and maximizing airflow are critical. The open design allows unrestricted air passage while the polymer material acts as an insulator to prevent heat from the engine from reaching the carburetor.

so far so good!

Easy to navigate. Good pricing

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

I wish they would put the car models it may fit

They had exactly what I wanted (Cyclo Max Clean Orange Powered, and the price was the lowest of any other sight).

Ordered my b pillars for my rsx. Pretty quick shipping and perfect fitment. This was by far the Cheapest price I could find and I am very satisfied. I recommend ordering from here
