Injen Aluminum Air Filter Heat Shield Universal Fits 2.50 2.75 3.00 Polished

A Universal Aircraft Grade Aluminum Shield That Blocks Engine Bay Heat From Your Air Filter

This Injen polished aircraft grade aluminum heat shield is built to keep radiant engine bay heat away from your cold air intake filter. Hot air robs an engine of power because it is less dense, so blocking that heat helps the intake draw in cooler, denser air. This universal shield uses adjustable mounts to fit most air filters with 2.50 inch, 2.75 inch, or 3.00 inch tube diameters, making it compatible with a wide range of Injen intakes and other aftermarket cold air intake systems. The polished finish adds a clean, factory built look under the hood while the solid aluminum construction stands up to years of heat cycling and engine bay exposure.

FAQ

The HS5000P is a universal polished aluminum heat shield from Injen Technology designed to protect a cold air intake filter from engine bay heat. It fits most air filters with 2.50 inch, 2.75 inch, or 3.00 inch tube diameters and is not vehicle specific.

Because it is a universal part, this heat shield fits based on the tube diameter of your air filter rather than a specific make or model. Confirm your filter measures 2.50 inch, 2.75 inch, or 3.00 inch before ordering.

It is machined from aircraft grade aluminum and finished with a polished surface for both durability and appearance under the hood.

Yes, all hardware needed for a complete installation is included in the box.

Most installations are straightforward and can be completed in under 30 minutes using basic hand tools.

Because the mounts are adjustable and the shield is universal, it can work with many aftermarket cold air intake systems that use a compatible filter tube diameter, not just Injen intakes.

This heat shield is backed by the Injen Technology Limited Lifetime Warranty against defects in material and workmanship for the original purchaser.

By physically blocking radiant heat from the engine bay from reaching the filter surface, this heat shield helps the intake draw in cooler, denser air, which can support more consistent airflow and power delivery.

Yes, the polished aluminum finish resists corrosion and is designed to maintain its appearance under normal engine bay conditions over time.

Install Instructions

1. Confirm your air filter tube diameter is 2.50 inch, 2.75 inch, or 3.00 inch before starting installation.
2. Loosen the existing filter clamp and position the heat shield around the filter housing.
3. Adjust the mounts on the shield to match the filter tube diameter.
4. Secure the shield in place using the provided mounting hardware.
5. Tighten all bolts and clamps to ensure the shield is stable and does not contact moving engine components.
6. Check clearance around the shield and intake tube before starting the engine.
7. Start the engine and inspect for rattles, looseness, or interference, and re-tighten hardware as needed.
