EFI 4150 DBW 16" AIR CLEANER

Fits GM LS3 Style DBW Throttle Body

Part Number: HO120-501

RetroFilter air cleaners cleverly hide an LS drive-by-wire throttle body inside to maintain a low height and classic looks. Utilizing a hidden opening in the base to hide unsightly wiring from the throttle body, this trick air cleaner allows you to experience all the benefits of modern technology and keep the vintage look you want. Pair with any Holley intake manifold with a 4150/4610 square bore flange for maximum aesthetics and performance.

The opening is 92mm but any 4-bolt pattern LS throttle body will physically fit. We recommend the LS2/LS3/LS7 style but the L33, L76, and L92 should also fit.

Features:
- Allows full EFI functionality stealthily hidden within a traditional looking air cleaner package
- Each kit includes a 3-inch tall, pre-oiled, washable and reusable premium cotton gauze filter element
- Adapts to LS style drive-by-wire throttle bodies found on the LS2, LS3, LS7, etc.
- Can be installed on any vehicle running a top mounted 4150/4BBL EFI capable intake manifold with LS3 DBW wiring components
- Stamped aluminium lid and base for optimal durability and light weight

* Requires adapter to connect to 4150/4160 square bore flange style manifold - Holley EFI part # 17-93 is recommended.
