Universal 4" Turbo Inlet Spool Billet Turbo Guard
The Spool billet turbo guard fits 4 inch turbo inlets and keeps large debris out of the compressor on setups without a filter.
Why you need it
On open or unfiltered intakes, a loose bolt or rock can wreck a turbo in an instant. This guard is machined from a single piece of billet aluminum with a hexagonal mesh that stops larger debris while keeping airflow disruption low. An inner cutout seats on the turbo lip and a set screw locks it tight.
Fitment
Universal. Fits turbochargers with a 4 inch inlet. Check your inlet size before ordering.
Features
- One-piece solid billet aluminum construction
- Hexagonal billet mesh pattern
- Inner lip cutout that seats on the turbo inlet
- Set screw lock for a tight, secure fit
Good to know
This is not an air filter and does not stop fine particles. It is a layer of protection against large debris. The turbocharger shown in the photos is not included.
