Holley 2300 4150 4160 Annular Booster Insert 12 Hole .500 I.D. Black QFT AED CCS
Description
  • Annular booster inserts with 12 discharge holes to improve fuel atomisation and throttle response
  • .500 inch internal diameter suitable for performance Holley-style carburettors
  • Billet construction supplied as a complete set of four inserts and four banjos

These annular booster inserts are designed to upgrade or replace existing boosters in Holley-style carburettors, improving fuel atomisation and drivability across the rpm range. Each insert features twelve precisely sized discharge holes to deliver a finer fuel spray, helping reduce flat spots and improve throttle response.

The inserts press into the booster banjo and are supplied with matching billet annular booster banjos. Installation requires a swedging booster installation tool to correctly seat and secure the banjos.

Specifications:

  • Insert internal diameter: .500 inch
  • Discharge holes: 12 holes, .062 inch each
  • Press-in surface diameter: .80 inch
  • Overall insert length: .88 inch
  • Colour: Black
  • Material: Billet aluminium

Kit contents:

  • 4 x annular booster inserts
  • 4 x annular booster banjos

Notes: A swedging booster installation tool is required for installation, or contact us for fitting service. Always confirm compatibility with your carburettor before purchase.
